Shaft drive slack question?

[lrgguy]

I was having some nasty knocking sounds coming from my bottom end . However they went away after doing a oil chanfe and a few adjustments to my clutch cable . Also replaced my tack cable and the raddle went away ..

Crank endplay........ The drive gears to the trans are angled, so on or off load will cause the crank to move along the axis of rotation.

As the motor loads and unloads the crank moves back and forth.

With the ignition cover off I can watch the crank move in and out as the motor is revved. Spec is .5 mm, it's moving more than .5. Manual says replace case or crank, which ever is further out of spec, there is no thrust washer.

Ride it until it blows, if it does, keep an eye out for a spare.

Fortunately, at decent rpm,the magnets in rotor act as damper to this movement plus you got the 60psi oil pressure squeezing out along crank bearings- no problem!

Unless one of your oil passages is blocked by a few wayward blobs of RTV.

Highly doubt it.

Somehow this doesn't surprise me.
