Prop governor mounting question

[Charles in SC]

I am in the throws of mounting the prop governor. My question is that the Lycoming website shows a spacer between the governor and the engine. Is this needed and if so where can I get one?
Also, the studs that are used for the governor and throttle body mounting are coarse thread like 5/16-18. Is this correct? Maybe they just have not changed them since the 1920s because of liability. What about the nuts for these? Should I use the little thin ones they put on it at the factory?
Thanks in advance!

What you need is a lycoming prop governor drive adapter (do a google image search on the phrase and the first few photos will be of what you need). Another part of the system is a line or hose that goes between a fitting on the drive adapter and the front nose section of the engine case.
If you don't have these parts on your engine, it is possible (but not a certainty) that your engine is not capable of using a constant speed prop.

Don't forget to check the crankshaft for presence (or absence) of the appropriate plug(s).

This is a new Lycoming IO 360 M1B that I ordered through Van,s. The line to the front of the engine is in place. Maybe I am seeing things on the Lycoming site. I will go check again.

I just took the Hartzell governor with the instructions with it and bolted it on. I used the Lycoming torque on specifications provided with the engine. Just be sure to use the gasket with the screen and point it in the direction that it fits nicely and does not crush the screen. M1B and governor from Vans. The engine case is bolted together with nuts , "the little thin ones", that came off the cover plate. Is there some reason for concern?

What are you missing?

Then it should be all set for installing a gov.

My question came from reviewing Lycoming SB 1438A for installing propellor governors on dual magneto engines that states that P/N LW-12347 is required with some prop governors. It does not say which ones. Since nobody else seems to have worried about this and just bolted it on maybe that is what I will end up doing but I think I am going to give Lycoming a call anyway.

Here is a thread I just started to clarify this. YOU NEED THE PLATE!
