Title: '54 Plunger B31 - should I have a ball bearing
Post by: Fraz on 06 May, 2025, 19:01
My bike has a ball bearing that sits in the clutch adjuster (part #31) and is pressed on to the push rod by part #30 when the clutch is activated.

The parts diagram attached doesn't show this ball bearing

Should I have a bearing or not?
That's my question (having mushroomed two push rods)

Thanks

Can only comment on the s/a version but the ball is set into the adjuster screw on the lower pivot arm
