what is the difference between the 23 spline and 18 spline throuout bearings ? I assume that the 18 spline throuout bearing has a bigger bore size.

If I switch from a 23 spline A833 to a 18 spline transmission, can I reuse the 23 spline throwout bearing and clutch fork or do both need to be bigger ?

thanks in advance up

thanks for the reply :-) 0.052" is not much of a difference. Would both input shafts use the same bearing retainer sleeve or do these also have different diameters ?

The big one will wobble on a 23 spline.Summit gave me the wrong one once.Tried it on my 23 spline and no way would I use the hemi one.The sleeves are different as the 18 has to be bigger to fit the shaft.Rocky

Clutch fork is the same, the bearing is different though as stated

Clutch fork, flywheel, pressure plate and bellhousing are the same - everything else is different.

Many thanks for your answers :-)

Would anyone have the actual diameter of the 18 spline sleeve ?
