I almost hijacked another thread where key/keyway problems were being discussed, but decided to post my own.
Note, I also originally posted in 2-stroke engines instead of Transmission / drivetrain. I just deleted old post and reposted before anyone responded.
On the HT engines, the bevel drive gear from the crank fits on a keyed, tapered shaft.
It is secured by a thin lock washer and screw.
What is the proper assembly technique? Qualitatively, what should the clearances be like between the gear keyway and the key?
How much are we allowed to "tap" the gear onto the shaft without damaging crank seals and bearings?
Can't put much force into turning the screw without buggering the head on it, so I assume it is not intended for pulling the gear down much.
I figured we seat it onto the shaft with a few light taps, and then tighten the screw as much as possible. And then the torque is primarily transmitted by the taper-fit, not by the key, right?
Or wrong?
Thanks guys!
