Gearbox input shaft bearing failure?
Posted: Sat Oct 09, 2021 1:14 pm
The guilt and the curiosity were eating me alive.
I couldn’t wait any longer to receive the address and deliver the gearbox (sorry Mr. S), so I decided to use the museum shop to open the gearbox myself and try to find out what is wrong.
Following the Barrington, if you don’t have one you should get one immediately, with the help of Dave and Peter I open the gearbox.
The Barrington shows a very simple tool to separate the cover and Dave used the vertical mill to fabricate one.
Since the kick starter lever was stuck in place, we couldn’t move it out of the way as instructed by the Barrington, but with a lot of patience we manage to separate the cover.
It took a lot of heat, a little violence and the pulling of the outmost bearings to remove all the shafts.
It looks like cage of the input shaft bearing failed. It broke apart tangling itself in the drive gear preventing the shaft from rolling freely, seizing the gearbox. All the balls are shift together to one side.
That is what I can see, I don’t know is this is the cause or the consequence of something else.
What do you think?
