Clutch problem L26 in 240z

Recommended Posts

Just hooked up my L26 hooked to my 240z flange type gearbox and it appears that the clutch/flywheel is too thin

 

The clutch fork hits the bellhousing before/as it starts to depress the clutch

 

Is there any differences between 240z/260z in the gearbox/clutch area that would give this problem?

 

Likely has a 260z clutch.

 

Very frustrating

 

 

Thanks, Ryan

Seems there are differences, may even be 280 clutch

 

Does anyone know the longest thrust bearing carrier of the different models? Carrier needs to be a good 15-20mm longer to work properly

There are at least 4 (I know of) bearing carriers with different heights; try to find a zed wrecker or parts place that have several for you to compare your original and try to find a longer one. Bearing carriers and clutches are usually matched.

I had a similar problem with mine after fitting a new box and clutch, it was sorted by replacing the bearing carrier for a longer one. If you measure the one you have as a starting point, Stewart Wilkins Motorsport can supply them if you can't find them else where.

Sorted. Got one 10mm long, would have been nicer if it was a bit longer but was free and works so can't complain.

i had the same issue recently when I (apparently foolishly) used the carrier from the new gearbox instead of the old one.

I wouldn't necessarily recommend it, but as a bit of a bodge to get the clutch to engage correctly with the shorter carrier I just made a longer push-rod for the clutch slave. Possibly not a great long term solution for the clutch, but mine was stuffed anyway, I just wanted to test the box  ;)

 

That and I didn't fancy spending another hour doing gearbox-pushups!

FWIW there are 13 different height thrust bearing carriers listed on the Nissan parts database...
