First major problem with 50cc HT (first build)
1 week and 3 days old.
Problem: HT Bearing disintegrated to a flat square !
First 5 days, everything seemed fine excpet for the constant adjusting of clutch cable. I thought it was "normal" stretching, but it got beyond the beyond of adjustments.
Removed cover and notice no ball bearing.
Probed with magnet and nothing.
Inserted another bearing and then the pin seemed too long.
Shortened pin, replaced cover, all worked fine for a day.
Today a fellow MB builder helped out and we used compressed air to blow out the first bearing, stuck inside after all this time. It was flat and squared !
Replaced with new hardened bearing till I got home and simply tried to replace the correct length standard HT pin.
The standard HT pin now seems too long.
So it ( the clutch ) works somehow with the new non HT bearing and shorter HT pin.
Why won't the correct length HT pin fit in far enough to bolt back on the clutch lever cover ?
Has anyone else had the same problem of the ball bearing disintegrating to flatness ?
Do I now include the ball bearing in the, quality upgrade kit, thread to ?
