Roll pin on dizzy


Recommended Posts

The cam driven gear on my dizzy exhibits noticeable play on the shaft. I knocked out the roll pin and there is nothing that looks like damage, it looks like it was made like that. The id of the roll pin hole in the gear is however smaller than the id in the shaft by about 0.1 mm, hence the play. What do do? Put it back don't worry about it? Whack in a marginally bigger roll pin? Bore out the gear whole to be the same as the shaft? Abandon it and megasquirt? Suggestions welcome.

If it's only 0.1 difference on dia, I wouldn't have thought it would flop about that much. In my experience the wear occurs in the hole though the drive gear, in the form of an elongated hole. A new roll pin might help perhaps, then go from there.
