Pre 101 Clutch side bearing

    The transmission clutch side bearing for the 101 is a deep groove ball bearing, code 6207.

    I am looking for a bearing for the pre 101 i.e. early scout and that bearing needs an offset (inner offset one side and outer offset other side) for the correct fit of the smaller clutch basket into the transmission housing.

    A vendor offers a 7207  angular contact thrust bearing with this offset.

    Should i be affraid that this bearing can cause the clutch basket to wobble and premature wear the clutch basket driven gear set or should i just reduce the aksial play on the main shaft to a minimum.

    Since the basket gear tooths are angular cut, the force will be trying to pull the basket outwards, same direction as if the clutch is activated.

    Kind regards Henrik

    Hi Henrik. Walkers offers a bearing and spacer replacement. The advice i was given by someone with more experience than me with these early motors was to set a minimum end float. He said that whatever you do, after a few miles, the end float wil have increased by 2 or 3 thou of an inch, so set them up as just free, with a minimum end float as is possible, barely measurable, lets say 0.001”. May take a few tries to get it right without significant preload on the bearing, and you will need to be fully tightening the nut to check each time, but the couple i have done seem to be working fine so far. Will be interesting to see what other people say.

    Please let us know how you go, and what other advice you receive from elsewhere.

    Tim
