Lycoming O-145 Parts

Re: Lycoming O-145 Parts

I know the original exhaust stubs were swedged in, but I think there was a service bulletin to have them threaded and screwed in.

My mechanic and I pulled my o-145 today and I need to find parts. I need the aluminum head gaskets and the copper crush head gaskets. One of my exhaust stub is also cracked. Can it be replaced? Any direction on where to go for parts, and advise on he exhaust stub would be appreciated. I also need to find new rubber motor mounts. I would love to get this bird back in the air. It is a nice little Taylorcraft. I am in Arizona.

The exhaust, check with Wall colomony

I don't think he needs exhaust work. I thing it is the exhaust nipple in the cylinder head that is the issue.

Has anyone got some pushrod tube seals from Hackenburg recently?

Hello All.
I was reading this post on the O-145 and wanting to get some more information about soild copper fire rings. What are the drawbacks of them and Why?
Also I am making gaskets thru a local gasket shop in my area. So far I have top, oil sump, accessory and valve cover gaskets readily available. As well as the aluminum head gaskets. I am currently working on a push rod tube seal this the outfit. They seem to fit great, but my project is not done yet so I haven't been able to test them. They are made of Viton and are about $225ish, for a set of 16, to have made, however I cannot find any NOS ones. Also any leads on cam bearings or any bearings for that matter. Thanks

Need some valve cover gaskets and some dual plug cylinder heads for a Museum engine I'm building. Not going to be airworthy but needs to run. Let me know your prices. Maybe Eric will chime in on it. Tried to leave a PM but was unable.

Pure copper does not last as long as a stainless or steel fire ring, that is why a lot of race cars have wire orings grooves into the blocks and heads when the run the soft copper gaskets.

Hello, again.
I may have found a supply of the copper crush gasket. But I need a NOS one to compare it to. Mostly for measurements. They are about $10 a piece, but readily available. I am wondering if anyone has one unused that I may borrow or buy to make a side by side comparison. Thx
