TO30. I just replaced both the crank and cam timing gears (new ones were Tisco and A&I brand respectively). There appeared to be "some" backlash between them but very little (I did not actually measure it with a feeler, but turning the crank did show a wee bit of delay in the cam gear turning). There is a loud whine when running the engine which is worse at lower speed. Does this indicate too little timing gear lash?
I replaced the old gears (which had a huge backlash) to try to get a minor clucking sound under control. Now I have a bad whine. The crankcase has an "S" stamped on it and I assume I used standard gears because they were not otherwise designated. So I thought the lash would be about right. Could the gears manufactured by different companies be incompatible?
I could put one of the old gears back in to increase the lash...or...could I just run it and hope the gears wear into each other?
Has anyone had this issue? Any suggestions would be very much appreciated.
