[QUOTE="greg brillus, post: 148711, member: 597"] Craig, I've seen a couple of Alton's used on Comet engines were they become very noisy, the shaft bearings gone........this was almost certainly due to the gear meshing being too tight........It can be tricky as the magnets in the Altons are very strong and perhaps the back lash check is not done correctly because of this.......Given this issue, you should avoid using too large a crank gear, as this will ultimately lift the large idler assembly further up, this will take away any clearance for the meshing of gears including the Alton........had one do this recently and the Alton was brand new less than 12 months ago........ Cheers. [/QUOTE]
