Os Giken Clutch Install Question

[berzerkled]

For anyone here that has an OS Giken twin plate fitted in their car, did you have to cut down the part of the input shaft where the release bearing slides on? We finished the install and started the car and had some loud grinding, so ripped everything apart again and it turns out the brand new release bearing is pouched as it was rubbing on the pressure plate. I also found out the wrong part number was installed for the release bearing sleeve (well not wrong but a different one than what OS Giken says on their site). Could this be the reason why it looks like it was grinding on the input shaft sleeve?

The car is an '89 GTR. Thanks..

To install the OS Twin ( Push Type ) You will need a different thrust bearing carrier being Nissan P/No. 30501-U0200 and use with Nissan Thust Bearing P/No. 30502-14601.

Make sure you also have the correct Flywheel to Crankshaft bolts ( shorter than the normal nissan ones by like 6mm ). You can cut yours to suit if prefered. You should not need anything else.

okay thanks

we'll get the bolts modified as well. it must have been the wrong clutch sleeve that casused the wear on the input shaft sleeve then i guess. would that be why?

Hard to confirm that without actually seeing it but I know mine was making the wrong noises and the clutch engagement / disengagement point was all wrong until I got the correct carrier / bearing combo. ( Note: those part numbers come directly from the O.S.Giken catalogue )

With the bolts, check exactly how much needs to be cut off.

I'm a bit concerned that you actually got to the point of running the car and possibly not having the bolts securely holding the flywheel / clutch on ! That itself might be where the wear came from.

yeah the bolts were all the way in, shouldn't be a problem there, but we're going ahead and taking 5mm off the input shaft sleeve

the bearing and sleeve are finally coming in tomorrow, should be installing it all again tomorrow night. will let you know what happens!

thanks again

[berzerkled]

well it turned out to be something else...so the input shaft doesn't need to be modified at all

So was there some "super strange" problem or was it one of those "super stupid" things that we all do ?? Remember, we all learn from eachother's mistakes.
