R22 drive belts
The drive belts on my R22 have been excessively tight ever since its rebuild 2 years ago. The adjustment is on its end stop and still they turn the blades at start up. I have tried the usual remedies of shutting down with clutch engaged etc and discussed the problem with the factory without any real resolution. I eventually evolved a technique where I engage the clutch motor for about one minute and leave it like that for 30 minutes or so before running it to fully disengaged immediately prior to starting, thus pre stretching the belts. This has given moderate success. However yesterday my starter motor failed by cracking its casting at the ring gear end, no doubt due to the excessive drive train loads over a two year period.
Has anybody found a proper solution to this problem?
