AncientGeek Posted February 23, 2011 Share Posted February 23, 2011 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.

mickeyw Posted February 23, 2011 Share Posted February 23, 2011 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.

AncientGeek Posted February 24, 2011 Author Share Posted February 24, 2011 New roll pin seems to have done trick for now... thanks. I suspect the play will eventually come back, but gives me a bit more time to pontificate about Megasquirt. Quote Link to comment Share on other sites More sharing options...
