My Posts This: Topic Forum | the measurements were done with the motor out of the heli. The glow plug was also removed from the heli.
The clutch was removed from the flywheel, and the flywheel was removed from the engine.
The engine, still bolted to the engine mount, was plased horizontally in a vise (just snug in the vise). The runout was checked at the base of the crankshaft (no runout here); then the flywheel was screwed on to the crankshaft. The runout was checked on the outside of the flywheel, and then on the inner rim (1 thou). The prop nut was replaced (it helps if you remove the backplate and use one the OS crankshaft locking tool - rick's had one for the 50, 60 size engine). The clutch was then installed onto the flywheel, and the runout was checked at the base on the clutch shaft, and the tip of the clutch shaft(1 thou).
I am glad it all worked for me with just cleaning the parts. I brought a file and sandpaper with me, thinking I would have to do some work.
It would be great if others share how they got a bad runnout reduced.
BTW, I flew today, and it was smooth as silk.
