Rennlisters,

My 92 964 Turbo is in need of a new clutch. I'll be doing the work on it, but wanted to check in with the brain trust before going ahead.

When I did the clutch on my SC, I took care of a few of the leak prone items as indicated in Wayne Dempsey's book. I'd like to do the same for the Turbo. I'm unsure whether most 930 seals will work on the same engined 964 Turbo.

Here's my "while you are at it" list. Please chime in additions:

911-606-230-00 Oil Pressure Switch, 911/911 Turbo 1969-89
930-107-791-02 Crankcase Breather Cover Gasket, 911/911 Turbo 1974-89
999-113-426-41 Flywheel Seal, 90x110mm, 911/911 Turbo 1978-89
999-704-172-50 Oil Pump Seal, 911/911 Turbo 1974-89, 2 req, each
999-704-173-50 Oil Pump to Right Case Half Seal, 911/911 Turbo 1974-89
999-707-314-40 Oil Thermostat O-ring, 911/911 Turbo 1965-89

999-119-017-01 Flywheel Bolts
999-510-015-02 Pressure Plate Bolts
950-116-813-06 TOB Guide Tube
950-116-080-08 Throw out Bearing
999-113-326-41 Transmission Main Shaft Seal, 911 Carrera 2/4 (1989-98), 911 Turbo (1989-98)
950-116-237-50 Slave Cylinder, 911 Turbo 1991-94
964-147-187-03 Power steering belt

Does anyone have experience with a lightened and/or single mass flywheel?

I've got new spark plugs, alt belt, AC belt and fuel filter ready to go in. I intended to adjust the valves while the engine was out as well. Pelican says that the release fork is NLA.

Clutch slave rubber hydraulic line is probably shot, get that too. And probably a new slave as well they are not that expensive.

good idea Jerry. Hose and slave. I'll get the engine sound pad too. Keep the ideas coming.

Get this soundpad, i bought the porsche factory one and it is a total piece of crap. This one is way good and tough enough to survive the install.

You might want to adjust the valves and put new plugs (maybe wires?) in it while it's out as well. Power steering belt??

i would install a lighten flywheel kit, they are getting hard to find, but worth the money....if the car has big horse power then you need to get the pressure plate from porsche off the 3.6 turbo...

JamesE

Full engine rebuild, might as well do the gearbox. Suspension is probably shot, so do that. If there are a few stone chips a full respray is the way to go,...

Yea.........this really is the best (most comprehensive) answer of all.

Just finished doing this on the 964 page, here is what we came up with:

Clutch, flywheel and fork
Check the clutch fork shaft and bearings
Clutch slave cylinder and cylinder hose
Valve covers check, replace seals
Valve adjustment
New spark plugs, plug wires
Power steering pump belt
Engine mounts
Oil lines (in rear wheel well)
Change the RMS
All seals
Secondary distributor drive belt
Power steering pump o-rings
Change the power steering reservoir supply hose
Crankshaft seals
Blow out the cooling fins
Fuel filter and alternator
AC and cooling fan belts
Inspect the rear suspension CV boots shocks, etc.
Check engine tin
Starter motor
Insulation blanket
Oil temp and pressure senders and seals
Crankcase breather line on top of engine
Alternator motor
Hot air lines from engine to chassis
Clean/replace injectors

JamesE's recommendations are perfect I had just done the suspension, so that might be the only thing that I could skip.

Boeing717 thanks for the tip on the soundpad.
Vincent, is there a recommended flywheel? Will I need a different clutch set up? I do not have more than stock HP, but was going to go with the Sachs Sport setup. According the Pelican, its the same pressure plate for the 3.6
Mada1 thanks for your list.

Is the hose that connects to the slave part# 964-423-477-00-M33 ?

Boeing 717

That is the part number i have in my records, although i didnt see an M33 in mine.

Vincent C.

you say the motor is stock, than you can get a sachs lighten flywheel, clutch kit, it should have most everything you need besides a guide sleeve. it will work just fine....if you were making more power than you will need to put a kit together, i always disagree with the commit that " its just the same"...if its not in a porsche box, its not the same, been there done that...i had to learn the hard way

Now this one makes me laugh....as I needed to do a valve adjust and leak down I ended up dropping the drive train and getting the trans refreshed, and had the bumpers repsrayed. Ya...watch out for the "while you're in there" scope creep.

Regarding the lightened flywheel...I'm running one but since the car came with it I can't compare. The pressure plate and clutch was a standard RS (996 part #) as I recall. I will say that the clutch effort is noticably stiffer over the stock unit. Enough to where you might want to try it first. It makes sitting in stop and go traffic even more miserable.

The M33 might be a Pelican tag.
