Question on main clutch disengagement bearing???

I have taken apart two differnent 22s and a 15 and the release bearing for the main clutch are differnent. One 22 is a thrust and the other 22 is a reguler ball bearing. The 15 is a ball bearing. The thrust would make more sence but not sure. The parts book does not say if its a thrust or ball. What is the right bearing??? Mike

Well I did some checking and cat use a regular ball bearing in the early models and then went to a thust bearing in the late models.

I always use thurst bearings.
