I just went through my 73 gearbox to check/change the Layshaft bearing. I found a NJ 203 "double lipped" roller bearing that was fairly worn. I replaced it with the FAG 6203 TB C3 bearing I had bought ahead of time. My question is about the shimming for the roller bearing. I did not disasemble the Kickstart shaft as the Pawl was new looking & this was not a "complete" rebuild, just being safe getting redy for a trip. Should I have looked for any shims that were there due to the old Roller bearing and or removed them? I had not thought about it until it was all back togeather, my limited understanding is the shimming was only needed for Roller type not ball type bearings. There is a percievable amount of movement if I pull on the kickstart shaft so I know it's not to tight. Thanks.
