After the debacle of my broken transmission clutch fork mounting boss, I search here on this board and some have suggested to upgrade to the new improved shaft with bronze bushing. I then order the shafy and bushing kit from PP. Although, when I received the new shaft it appears to be much longer than the OEM part. Am I missing something ???

Please help me determine which one should go in?
I have a G50/05 (1992 Carrera)

Based on this picture it is obvious that something is wrong,... what?

Thanks

Show me some measurements of the new shaft. I have a similar kit that my shop said they could not use because of it's size.

I have that kit installed on both of my cars. If you remove the bronze bushings and the end caps, the shafts should be the same size. To install, you use black bushings only, the bronze are not used. The black bushings replace the factory needle bearings.

Thanks Rob for the explanation, but even with the end caps removed the "New shaft" is still almost an inch longer than the other OEM shaft that I removed from my tranny.

I test fitted the new shaft with a new clutch fork without the brass fittings (since the new fork has its own poly bushings), and it is too long it protrude out of the bellhousing about 1 inch and the small angled bracket at the end will not mate with its fastning point.

I am at a lost and almost want to just re-install the OEM shaft and just buying new needle bearings. I need to reinstall the tranny and engine this weekend, so I need a plan quick.

Thanks
for all of the advise.

bump,..... Anyone at all has used this Shaft for a clutch replacement?

Here is a pic with measurement of the shaft that I picked up on Ebay a while back. How does that compare to yours? When I had the clutch replaced in my 92, the mechanic said that it would not fit, and promptly purchased a rather expensive replacement kit with bushings rather than stock needle bearings.

I was planning on ordering this? did anyone figure it out?

AS I said about, I have two of these kits installed, one in each car. I purchased my kits from EBS Racing. I used the shaft but not the bronze bushings. I have my tranny out and try to measure it or take a picture of it when I get home if you need.

Porsche resolved the problem the models prior to the 964 experienced by replacing the friction bearings with needle bearings in the transmission and using friction bearings in place of needle bearings in the release bearing. As long as you remember to lubricate everything properly with Olista Longtime 3EP then you should be okay. Every 964, 993 and 996TT/GT3/GT2 on the road uses them...

The bronze bushings replace the plastic bushings in the clutch fork, I would recommend using them.

As to the difference in the shafts, you do indeed have the correct replacement part. There is a cap that your old part is not showing. This new part does not use the plastic cap and is as a result slightly longer than the OEM part.

Give me a call if you have questions I will be happy to answer them in more detail.

I'm surprised Eric suggests running the bronze bushes - anyone know why he does?
Eric you have pm

Bronze should be both stronger and longer-lived than plastic.

jevvy964

The plastic bush that comes with a new fork is designed to grip and not slip on the shaft(aka factory setup with a shaft that pivots on needle bearings). The bronze bush is pressed into the fork instead of the plastic bush when being used on a solid shaft(aka the upgrade option).

Are you guys really just running the plastic bush with the solid shaft?

HiWind

No I'm planning on running the needle bearings - shd the shaft rotate freely once installed?

I have what looks to be Ali or steel bushes pressed into the fork.
