If you're feeling really ballsy you could replace the torque tube bearings while you're in there too. Getting it in/out is a bitch, but removing the guts of the tube and replacing the bearings wasn't as bad as people make it sound. It was time consuming, but that's about it. I can't report on putting it back together yet, but I bet it won't be that bad.

"installation is the reverse of removal"

impact gun and big air tank saves a lot of time.

I'll bet it does. My impact gun says not to use it for extended periods of time, so I did it by hand with the threaded rod/wrench method. It took a good 30-45 minutes and a million turns of the wrench to get the carriers out, but it beats burning up my impact gun.

Well because the car is built in a much smaller amount of numbers then toyota or GM. so replacement parts are not built in the same bulk as for GM. So yes prices will be higher. The quality changes too when paying for brands like VDO or Bosch.

So when changing a factory clutch to one from another car. Think about this. It's time to sell.. the new owner wants to change the clutch. they find a hack job of some other type of clutch, probably end up costing him more to get it done properly.

Sure, quality changes - but Sachs makes clutches for a bunch of cars. Porsche also uses parts from a bunch of different manufacturers in their cars.

I have to disagree with your second statement - if an owner wants to experiment with some other parts, then more power to them. Don't tell them it's time to sell just because they don't accept paying for limited production run parts. There is NOTHING special (construction wise) with the 944 Sachs disc. Heck, if these clutches work then great. I saw that the Ford clutch actually had a wider contact patch than the Porsche clutch did, it might even be theoretically stronger.

The only scenario that I don't condone this is flipping a car. Don't skimp on parts when flipping - that is shady.

Hey guys,
I'm brand new here. I own 88 944na and I'm up for a clutch work. I'll go with the Ranger disc, I also found out that ARP 171-2801 flywheel bolt kit should work just fine with the Ranger disk. Anyway, my question is about the clutch release bearing, after quite a research I found out that SKF N1850 which costs only $20 on ebay fits 83 and 84 944 na. do you guys think that this will fit 88 as well? The clutch release bearings that they sale everywhere fit all vehicles from 83 to 91 but the description on the SKF bearing is very specific about the fitment only 83 and 84. Thanks

FWIW
I had a local shop reline my clutch disc, $60. I'll "clean up" the flywheel and pressure plate surfaces, they look good, no heat discoloration that I can tell. Supposedly this car only has 17,000 miles on it. I don't know about that but the clutch looked pretty good. The release bearing's spring washer had failed, probably be cause it was all siezed up from sitting around until pressed back into service and it just couldn't take it. I'm keeping this job cheap since it's my son's car and he has no money, I have a shop and tools so worst case scenario, we go in after the clutch again, no big deal. If I"m wrong, I'll admit it.

After I pulled my engine, I pulled the clutch off as well..I had the disc relined for about 50.00 or so. Reground the flywheel, and the pressure assembly looked great. Had that bead blasted then clearcoated it to slow down any rust. Replaced the T/O bearing with a new Sachs one. Hope that it will perform nicely..once the engine is back in it and hooked up. The T/O bearing was the most expensive part of the entire arrangement...my .02 cents....

That looks like a clutch release bearing for the 924 non-S with the VW Van engine. They are confused by the RoW production of the 924 that overlapped the early 944 with the Porsche engine.

Still...have to wonder if the main bearing of the 944 TOB is a replaceable piece...
Anybody got a junk TOB they could send my way for investigation?

I'm wrapping up this project now. It's taking me a month on the weekends. Why.? Because while your in there you might as well rebuild the torque tube, and while your at it lets change the crappy heater valve to a metal one so my new clutch job doesn't go kabluee when the plastic valve fails. That means I have to drain the coolant. And I hate, I mean hate putting coolant and bleeding the system. Let's not forget that I need to bleed my brakes because when I pulled the TT out I had to disconnect the rear break lines!

The bad thing about "experimental" clutch discs, is that they tend to vibrate more than the stock units. The factory Turbo S disc has more springs in it than the NA for this reason.
