Not that I have one to offer but what part # are you after? I'm sure there are at least two possible. Steve (CTR)

I used the Minispares C-22A1731 with their 22G1100 laygear for my 333 build with no issues during assembly.

Just make sure if using the new longer type needle roller bearings that you get the retainer circlips in the right place.

Thanks for the replies, think I need the gear too. Only very minor pitting but better safe than sorry while it’s stripped down.

May I ask is it only 22G1100 laygear need those circlips to retain the bearings? As I just assemble my 3-synchro straight cut laygear and can't recall I used or needed any circlips at all!

22G1100 helical laygears from MS etc. have both grooves machined, so either arrangement of long bearing, or short bearing + spacer, can be used. I don't know about other laygears, but there seem to have been two basic styles.

The earlier laygears used an inner circlip, then a spacer, then a short bearing, then an outer circlip to capture the bearing inside the laygear as a complete assembly. Most of the workshop manuals and websites show this arrangement in their assembly diagrams.

The later type used the inner circlip with a longer bearing and no spacer. These longer bearings 'float' against the thrust washers on the outer ends, and do not use the outer circlip. I posted a corrected diagram on this thread: viewtopic.php?p=227859#p227859

Caution: When the laygear with the longer floating type bearings was first introduced, it had no outer circlip groove machined. Those laygear used a slightly different longer bearing type but with narrower cage ends and rollers that extend almost to the end of the cage. Don't use those transitional bearings on a modern laygear which has the outer groove, because the rollers running over that groove can cause premature bearing failure.

[There was a discussion about it previously from someone else on here I think... most of the currently available longer bearing have wider cage ends and slightly shorter rollers, so they don't run into the area of the unused outer circlip groove. It's pretty obvious when you come to assemble whether you have the correct bearing type.]
