Spoiler - Installing Front

I just put one on my car. These are the steps I took:
1. Put some masking tape on the front edge of each fender where the two studs will go through.  Carefully mark where the studs will go. Center punch and drill the holes.  Take the tape off.  Put the studs through and put the nuts on.
2. This next part is tricky to describe.  The holes in the spoiler are slotted, so you want to mark at the end of the hole closer to the center of the car so that if you need to stretch the spoiler to make it fit, you have some lattitiude.  Mark, punch, and drill the next bolt holes on each side. Bolt them up.  Using big washers here keeps the spoiler from slipping overthe nut as you stretch it.
3. continue this way, one hole on each side at a time, putting the nuts on to hold the bracket/spoiler, but loose enough so you can stretch the spoiler if needed.
4. Go back and prime/paint the holes and then repeat the process to bolt everything up.

Sometimes I found the bolts didn't seem long enough to get a nut on, but if I put a block of wood on edge under the bolt and then jacked it up a LITTLE, it would compress the rubber enough to get the nut on.

Having somebody to stretch the spoiler while you mark and bolt it up is helpful; it's hard to do all by yourself.



Sunroof - Height adjustment

This is covered in the Haynes Porsche 911 Repair manual, Chapter 10, Section 15 (pg 247 in my edition).   A somewhat clearer description is in Morgan and Porter's 'Porsche 911 Purchase and Restoration Guide', pg 129-131.

The  height adjustment for the front of the sunroof is done by two knurled knobs on each side, which are located under the front guide bolts - these are at the front of the panel, parallel to the windshield, and are supposed to be covered by a black plastic trim piece which slides off (I assume you have slid back the upholstered inner frame of the sunroof and are looking at the metal panel). 

Take of the trim, and you will see two bolts on each side.  Beneath them are the adjustment knobs.  Adjustment is a simple process of raising the passenger side of the panel until it is flush with the roofline.   Rear adjustment is possible by fiddling with the rear bolts that hold the panel to the cables.  Generally the cables should not need adjusting; try this first and see if it works.  Also, make sure that the cable guide are attached, and that each has a thin, U-shaped rubber or plastic insert to smooth operation.

There are 4 adjustments to your sunroof if it the same as my '82 (pretty good chance).  One in each corner.  The fronts are different than the rears.  The first thing you have to do is remove the inner cover that has the matching head liner material.  To do this:

1.Open roof about 3-4 inches.
2.Gently pry the front edge of the inner cover downward and away from the sunroof.  You might want to use a dull putty knife, but be very gentle.  There should be about 6-8 snap in connector things to unsnap from the sunroof.  Mine were really stubborn to get out the first time. Then again, I had no headliner so I could be a little rough. After you have detached the inner cover it should be able to slide all the way back. 

In the front you will have a guide for each side.  Each guide is attached to the sunroof with two screws.  In-between the guide and the sunroof where each threaded screw hole is, there will be a knurled (grooved pattern to help grip things that are round) round spacer.  There should be two per individual guide.  If you twist this spacer it will change the height that the guide is from the sunroof. Try to keep both spacers relatively even and adjust them appropriately.

The rear adjustment is more troublesome.  At the end of the cable is a part that slides within the rails attached to the body of the car.  This 'slider' has a short post sticking straight up from it.  The post has a vertical slot and is horizontally grooved on one side.  You will understand when you see it.  There is a corresponding grooved nut that fits this little post.  If it were on a shaft I would describe it as splined, but here it is only the mating of two grooved surfaces.  By moving this nut up/down to different groves you adjust the rear height of the sunroof.  To get at it you basically have to take your sunroof out to loosen the screw that screws into this grooved nut. 

To remove the sunroof:

1.Close the roof almost all the way.
2.Remove the two guides from the front of the sunroof.
3.Remove the two screws holding a flat spatula looking piece to
the sunroof at the rear (both sides).
4.Gently push the front of the roof up and out a little.
5.Slowly move the sunroof forward and out.  There will be some
long metal clips from the sunroof that run under some small diameter rods connected to the 'slider'.  They will make a loud 'snap' when they get out from under those rods.  Dont be too alarmed.  Be careful not to bend the rods or the metal clips.
6.The roof should come out relatively easily.

Now you can get at the screw to loosen the grooved adjusting nut. Adjust appropriately.  Installation of the roof is basically the reverse of the above process.  You must be careful about getting the long metal clips under the small diameter rods and it is probably the trickiest part of the whole thing.

I can remove and replace my roof in about 10 minutes now.  Took me about an hour the first time as I was trying to figure out the function of every thing.  Just be patient and you will conquer the sunroof easily.

I would rank this a 3-3.5 on a scale of 10.

Shift Linkage - Adjustment

1. Remove the cover plate on the tunnel, behind the front seats.
2. Place gearshift in neutral.
3. Loosen the shift rod clamp.  Turn the shift rod (by grasping the
coupler) to the right, as seen in the direction of driving.
4. Move gearshift lever to the left until it touches the stop, and
move it fore-and-aft until the lower section is vertical when viewed from the side (the fore-and-aft adjustment can be modified
to suit the driver, provided sufficient length of the shifter rod remains inside the clamp).
5. Lightly tighten the clamp.
6. Check if equally long travel is evident in gears 1-4, and that 5th
and reverse can be easily engaged.  Correct as necessary.
7. Tighten the clamp securely.
8. Shift into 5th gear, and check the shift rod for rotational play.
A definite (slight) amount of play must be evident.

This is also a good time to inspect the shift coupler bushings.  Be aware that some fore-and-aft play in the coupler bushings is required.

So for those who have trouble with type 915 transmissions and shifting, based on a broad statistical sample of 1....I conclude the following which is of no validity nor supportability.
Given that the synchro's are in good shape and they are adjusted right....the suckers are not hard to shift at all. Yes they baulk on forced shifts....but that is what they are supposed to do. If you shift smoothly and crisply  there are no problems...no need to run it through other gears at stop lights etc. The key is proper shift linkage adjustment.

So for those who are having problems, here is the "trick"

1. Check the bushings in your shift linkage. This includes the 2 at the coupler between the rear seats, the one under the housing which is in the hoop retained by the 2 smaller bolts on the shift housing and the cup at the bottom of the shift rod. Make sure they are in good shape, they are cheap and easy to replace.

2. Make sure that if you have a later housing, that the longitudinal pivot pin is nicely snug, not too loose. You can tell if you have this housing as it will have a lock nut on the front (visible when you peel back the rubber boot around the shift lever. Consider upgrading to the later (post '78) housing and factory short shift kit if you haven't already.

3. Make sure your clutch is adjusted right. It should engage about 1/4 to 1/3 up from the floor board (IMHO) and have about 20mm of free play, measured by pulling the clutch pedal back...as there is a spring which is pressing it towards the floor board, hence the bit of tension.

4. Follow the factory shifter adjustment procedure. It is as follows:

a) Take off the cover between the rear seats which exposes the shift coupler. Pull up the shifter boot, particularly so you can see the lower part of the shifter lever where it bends from "angled back" to more vertical.

b) Loosen the retaining bolt which pinches the shift rod on to the spline on the shift coupler. Let it be very loose.

c) WITH THE TRANSMISSION IN NEUTRAL, rotate the shift coupler clockwise when viewed towards the front of the car. You should be able to feel the coupler rub against the various shift stops as you rotate it back and forth. Rotate it to the furthest clockwise position, as seen when you are facing forward. Don't pretend you are Tarzan and turn it with huge force....lightly is all that is necessary..

d) Keep your hand on it and hold it there. Don't let it wiggle, if it does, turn it back to the furthest clockwise position.

e) Move the shift lever so that the more vertical part of the lever is vertical (ie 90 degrees to the level...sticking straight up so to speak). Move it so that it lightly touches the side of the shifter housing which is on the 1st/2nd gear side.....closest to the driver.
Again, gently.

f) They should now be properly aligned.....lever closest to the driver with bottom part vertical, coupler clockwise in the neutral plane.

g) Carefully tighten the pinch bolt. Make sure it is quite tight.

h) Check things out. You must be able to engage reverse clash free (give the gear a little bit of time to stop after you stomp on the clutch), shifting should get to all the gears easily when driving.....things don't work as smoothly when stopped and lastly,  there must be a little bit of rotational play when 5th gear is selected. This is checked by shifting into 5th, and feeling whether you can wiggle the shift coupler with your hand. It should just click back and forth slightly...not much, but clearly discernable play.

i) Assuming all is well, put all the covers back. If it is not
well....my fervent suggestion is that you START OVER at b. ....I have never had any luck fiddling with the linkage.

Drive and be happy.

Short Shift Kit - Install

Following are painfully detailed instructions on installing a Factory Short Shift into a 1978 911SC. They should be applicable for model years 1974 to 87.  This particular car had a "lesser" (crappy, not the Weltmeister) short shift kit already installed.  If yours doesn't, just disregard all references to the "aluminum spacer block".

Parts Involved:

Things the Factory SS kit includes:
1.Shift lever (longer below the pivot, slightly shorter above it)
2.Metal top plate
3.Rubber buffer plate
4.(2) Springs
5.Spring guide plate
6.Pivot cage
7.Pivot pin

Things you WILL also need:
1.New "crush sleeve" to fit shift knob on new lever

Things you MAY also need:
a.Shift lever ball end bushing
b.Shift rod front pivot bushing
c.Bushings for shift coupler
2.Shift knob, if you break the old one (I did)

Note:  Shift coupler can be easily inspected before you order anything. You may want to order the other bushings in case you find out the old bushings are bad once you have the shift tower apart.

Tools needed:
-5mm, 6mm allen wrenches (for shift tower bolts)
-10mm wrench (for shift tower top plate nuts)
-22mm socket (for late-style shift tower locknut)
-(2) 13mm wrenches  (to adjust shift coupler, can also use 13mm wrench and a low prolfile 13mm socket))
-Needle-nose pliers (for lockrings)
-Grease (for everything)
Beer comes in handy too, particularly in the adjustment phase.

Step-by-step instructions:

1.Remove center console if you have one.  4 screws around the perimeter of the back cover piece (where it joins the main console piece), pull off cover piece, then 2 screws holding down the back of the console and one (under the carpet) holding down the front.  The front screw can be tricky because the parking brake handle will be in the way.

2.Remove old shift knob.  If this looks to be difficult you might be wise to order a new one to keep handy & return if you don't need it. Mine was loose, so no problem removing it, but I broke the end of the sleeve part when reinstalling it on the (slightly larger diameter, apparently) new lever.  You will need a new "crush sleeve" (interference fit sleeve) either way since you'll probably mangle the old one getting the knob off.

You can probably avoid the breaking of the shift knob by waiting until afterstep 13, given that you have a vice in which to hold the old lever whilst you tap the knob gently off. You could also use a gear puller with a bit of wood or something under the centre "push" part to prevent damage to the knob, but likely a soft faced hammer or a bit of wood used as a buffer will do the trick.

3.Remove shifter boot.

4.The "late-style" (don't know exactly how late) shift tower has a locknut and allen bolt that position the forward end of the longitudinal pivot axis.  If you have this type of tower, use a 22mm socket to loosen the locknut BEFORE you remove the tower from the car.  I had to reinstall my (empty) shift tower just to get enough leverage to crack the nut loose.

5.Apply the parking brake and shift into neutral.  This will allow you to pivot the shift rod side-to-side as needed to reinstall the shifter later.

6.Remove the 3 big Allen-head screws (6mm wrench) that hold the shift tower to the car - two on the front side of the plate, one on the back.  At this point the tower should be loose, though it won't come off yet since it's still attached to the bracket that holds the front bushing for the shift rod.

7.Remove the 2 smaller Allen-head screws (5mm wrench) that hold this bracket to the shift tower.  On my car, these screws went through a 1cm-thick aluminum spacer block (part of the old SS kit) and then into the bracket, so the bracket was "hanging" from the shift tower base plate. 

8.At this point you should be able to lift the tower and shifter free of the shift rod.  The end of the shift lever is press-fit inside a rubber bushing that fits inside a cup on the shift rod.  You may need to tug a bit, but the bushing should pop out eventually.

9.Take the shift tower to a workbench (or a newspaper-covered kitchen counter for the workbench-challenged among us) to work on it, since it's got some small pieces you don't want to lose.

10.Remove and save the two 10mm nuts and lock washers that hold the plate to the top of the shift tower.  There are 2 strong springs inside this plate, on the left (1st/2nd gear) side.  If you have a vise or large C-clamps, you might want to clamp the plate before you remove the nuts.  If not, loosen the nuts first and then maintain pressure on the plate as you remove them by hand.  This keeps the assembly from "exploding" - which looks unprofessional, although you won't need to keep the springs anyway so it's no great loss if they wander off.

11.Remove the top plate, springs, the rubber buffer pad (shaped the same as the plate & directly beneath it), and the piece the springs run on, and set them aside.  The new kit has replacements for all of these.

12.Looking down inside what's left of the shift tower, you'll see the pivot cage that attaches the shift lever to the tower.  This cage has a pin running laterally (side-to-side) on which the shift lever pivots for fore-and-aft movement (i.e. 1 to 2, 3 to 4), while the cage itself can tilt relative to the tower to give side-to-side lever
movement.  Remove AND SAVE the two lockrings (C-rings) that hold the lateral axis (side-to-side-running) pivot pin in place, one on either side of the cage.  Remove this pivot pin and set it aside.

They are quite cheap from Porsche (like maybe a buck) if you do break them, however, there is usually a delay of a couple of weeks as the need is not all that common.

13.Pull the shift lever free of the pivot cage.

14.Remove the pivot cage from the shift tower.  On the late-style tower, you unthread the allen bolt that forms the front longitudinal (fore-and-aft running) pivot, then press out the interference-fit piece for the rear pivot.  I suspect an early tower would just have the interference-fit pieces on both ends.  To press out the pivot, I slid a breaker bar through the pivot cage, placed its flat edge against the pivot, then grabbed both ends and squeezed against the top and bottom ends of the shift tower.  This just pushes the pivot back enough that you can get the cage out.  On my tower, the interference piece had a spacer washer on it.  Save this washer too.

15.    Set aside the pivot cage.  Keep the allen bolt and/or pivot piece(s) and the washer(s).

16. Clean up the bits you'll be reusing:  lock rings, cage pivot piece(s), cage pivot washer(s), shift tower, 10mm nuts and lock washers.

17.Cut the bottom end off the bag that the shift lever's in.  Try to leave this bag over the top end of the shift lever until you have installed it in the tower;  this reduces the chances of scratching the paint.

18.Check the fit of the new shift lever in the new pivot cage.  I had to bend the cage walls out a bit and file the edges a little to get it to fit.  I suspect some drag is OK but you don't want it to bind.

19.Grease the pivot end of the shift lever and the pivot pin, then assemble the lever to the pivot cage and replace the lock rings.  With the shift lever positioned so it bends toward you, the pivot pin should extend out of the left side of the cage so it can engage the spring guide plate once the pivot is installed in the tower.

A good grease for this is Dow 111 silicone, non staining and won't drip off in hot weather, plus it doesn't smell.

20.Grease the cage's fore and aft pivot points (holes) and install the cage and lever into the tower.  If you have the late-style tower, replace the allen bolt and lock ring and adjust so the pivot cage has no fore-and-aft play.  I didn't tighten my locknut nearly as tight as it was originally;  I didn't see the point.  Use your best judgement.

For those who do not have the adjustable pivot, it is well worth getting an old housing or even a new one if you can justify the expense. The housing was changed in 1977 so all SC's have it. On adjustment, one trick is to not tighten the lock nut too tightly,
but rather leave it snug until you find the right tension for you. BTW, it never has to be too tight, as it doesn't get much stress.

21.Grease and install:  new spring plate, new springs, rubber buffer plate, metal top plate, 10mm lock washers and nuts.  A vise or an extra set of hands would be helpful in mounting the metal top plate, since you need to compress the springs while lining the plate up to (a) the studs for the 10mm nuts and (b) the two tabs of the metal plate on which the springs run.  It can be done solo, but it's not particularly fun and you'll need to curse a bit.

22.Clean and grease the inside of the shift lever bushing (if you're reusing it;  mine was fine) and press it onto the ball end of the shift lever.  This is a hard fit.  I held the lever vertical and pressed the entire tower assembly down against the table to pop it in.

23.Return the tower to the car.  Locate the bracket that holds the bushing in which the front end of the shift rod pivots.  Clean and re-grease the shift rod where it runs in this bushing.  Position the bracket so its tab (with the threaded holes) sits ABOVE the tunnel.  The big, non-threaded hole should line up with the threaded hole in the tunnel (where the big Allen bolt goes).  Note that if you are replacing a previous SS kit that used a spacer, this is a new location for this bracket - before it would have been hanging below the level of the tunnel.  If not, you're putting it back right where it came from originally.

24.Clean and re-grease the cup at the front of the shift rod that the shifter bushing fits into.

25.Lower the tower into place and fit the shift rod bushing into the cup.  This takes some finesse and luck.  It seems to work best with the shift rod held vertical.  If you have small, long fingers, you can reach in through the access hole in the side of the tower to help fit the bushing into the cup.  It should slide easily to the bottom.

26.Line up the holes that mount the shift rod bracket to the plate and reinstall these bolts.

27.Line up the holes that mount the plate to the tunnel and reinstall these bolts.

Make sure that you have the shift lever in the cup at this point, I have seen it shift a bit on its own.

28.Reinstall the shift boot and knob, using a new "crush ring" for the knob.  I think you want to put the ring all the way inside the knob, then press it onto the lever.  I tried putting the ring on the lever and forcing the knob over it, and managed to break the sleeve off of the knob.  Good luck on this bit.

You can put the shift knob on when this is all on the bench , where you can get at it nicely and not have to worry about damaging your interior.

29.See if you can get into any gears.  If you can't, don't despair, we still have to adjust the shift linkage.  But, it's helpful to figure out how "close" you are.  Return to neutral.

30.The cover for the shift linkage is on the tunnel just forward of the rear "seats."  Pull up the carpet, remove 4 screws and take off the cover.

31.There should be a rubber boot covering the shift linkage.  On my car, this boot was missing, so I don't know exactly how you pull it back, but I expect it's obvious.

32.Loosen the clamp holding the shift rod to the coupling.  I believe these are 13mm nuts.  I was able to put a box-end wrench on one and my crappy 3/8" drive socket wrench on the other, and just left the wrenches on while I did the adjustment.

One is 12 mm, the other is 13mm.

33.The Haynes manual recommends the following procedure for adjusting the linkage:
a.Pivot the coupler so it's in the 1/2 plane.  Facing the rear of the car, this is the counter-clockwise limit.
b.Position the shift lever against the left-hand stop and move it so the lower part is vertical.
c.Tighten the clamp and check the adjustment.

34.You may need to fine-tune this adjustment a bit to easily get into all the gears.  I had to move the clamp one spline over from this starting point so I could get to 5th and R.  Once you can see the coupler move as you move the lever, it should be obvious what you need to do.

35.As a final check, shift into 5th gear and make sure there is some fore-and-aft play in the coupler and linkage.  There won't be any play in 1st or 3rd; this is normal.

You must be able to get into reverse without grinding, and when you have selected 5th, you should be able to move the coupler between the rear seats slightly, otherwise things are too tight. Not much, but just a bit of rotational "wiggle" is necessary.

34.Button it up and go for a test drive.

Be prepared to adjust a few times if you are a fussy sort.

Good luck,
Scott Booth
