Unbelievable....just got a complete NOS synchro assembly ...I removed the two end syncro`s by removing the snap rings without any issues....then replaced them back into the drum assembly making sure that the syncro`s turn nicely after I installed the snap rings again and left them overnight soaking into a container of 90 weight mineral oil for transmissions.
Today I went to continue assembling the tranny and find that the syncro`s will not turn even tho I can turn the snap rings. They are frozen. ...Could the bronze liner that the syncro`s sit in have swelled causing this problem ???
