Propeller Governor Mounting Hardware

[OneTwoTree]

I PROMISE I’ve used the search function: here is my problem. No mounting hardware came with the governor. The instructions say follow the engine manufacturer. FOR THE LIFE OF ME I can’t find that in lycoming literature. Probably because they don’t support experimental like that. So I called van’s and they said use what is on the block holding the blanking plate on. So then digging through random bolts, nuts, ect supplied with the engine I can find the same items (but new) that are holding the blanking plate on. Great. HOWEVER I don’t love this. First off, why not use a metal locking nut (I know better than to use nylon in the engine bay) but a metal nut seems smarter than a locking washer. Also the locking washer is ever so slightly larger than the stud so it clocks a bit off. If this is what everyone does, I’ll go along with the tried and true method, but is this really how ever is mounting govenors?

Well if you don’t like the lock washers, I suggest you not look at some of the other bolts on your Lycoming……

Standard method of mounting accessories like prop governors, vacuum pumps, oil screen adapters, etc.

Paul, I certainly trust your option a lot. So thank you!

Looks fine to me as long as they torque is right. If uncomfortable, double nut it. That is about the most secure locking arrangement out there.
