Engine get tight when prop nut is tightned.
frank mccune:
Hello All:
Whenever I tighten the prop nut, my engine, it becomes very tight and difficult to turn. The engine is a HP .40 Silver Star. I have 6 other HP .40 engines that I have, do not do this. What is wrong? I can not see any difference in the way that these engines are assembled.
Suggestions/comments?
Tia,

you have a bearing that is not in properly, or not seated, OR you have a collet on the front that is not pushed all the way back to touch the inside race of the front bearing, most likely 1 of the 2

Yes the HP-40's used to have some .4 or .5mm thick brass washer behind the front ball bearing.

Is this engine recently, just put back together ?

Agreeing W/Randy about the botched collet syndrome, I've improperly done this .
