how do you get the prop driver installed on a nitro engine? Mine is a 60 size. Need heat on part or what is the easiest?

To put it back on?

Slide it on as far as you can by hand, then put a prop on and tighten it up like you're mounting the prop,, that should push it on the rest of the way until it bottoms out.

Good luck

Keep it simple and that is it. Thanks for the info , I will try that. Thing is super tight , can just barely get it on the shaft. Came off fairly hard too. Rest of the overhaul went sweet. I will get back. gphil

Heat will make it go on easier if you have a problem with it.

Tried heat but still was unable to even start it good in order to keep alighned. Came off there so should go back . Will see. gphil

Makes me wonder if it was damaged coming off, How did you remove it?

Ok fellas, the ole prop , nut ,washer and a little slow work got it back on. Thanks a lot for that idea,it worked great. So now I have a good .61 engine ready for a plane. No need for more input ,this place is the greatest. gphil
