Hi all,
Need your take after removal of my S130 gearbox at the weekend, which mates to my L28 engine with 280ZX 2+2 clutch.
Gearbox was removed in order to upgrade the clutch as it was slipping, now on removal I measured the collar out of curiosity and found it to be 30mm from the top of bearing to the top of the collar, please see attached photo.
My limited understanding is that when you are using a 280ZX box with a 280ZX 2+2 clutch, then you need the longer collar as the 280ZX pressure plate is shorter then the 240Z plate and hence you need the longer collar to make up for the length.
However if this were the case then why is mine the shorter one, and I had no issues changing gear whatsoever. Now I need to replace my thow out bearing and don't know whether I should source a 40mm collar and use that or stick with the collar I already have and just renew my bearing to that.
Also, does anyone think that my slipping clutch, when i hit 5,000rpm, can be attributed to the shorter collar being used?
Rob Gaskin wrote a very useful post on collar lengths but the attacment in his post has since expired, Rob could you shed some light here please if possible.
Thanks all.
