Hi All, Does the main bearings move left to right in the case as your ride & motor is heat soaked?

Specifically on '73 T140 type motor.
Thanks, Don

Bearings fall out when you heat the cases with a blow lamp on the bench.

To my tiny mind, the safest assumption is that they are not held tightly when the running engine is fully hot.

" the TS ball handles the thrust and so does a 3 piece roller". . How does a timing side roller control thrust like a ball bearing? The crank is free to float between the two roller bearings, not clamped to a ball bearing,Yes?
