How Hard To Remove/Reattach Engine Mount?

[gasman]

"Fortunately, both times, it was pretty easy to hang the engine (1.5 hrs the 1st time and 1 hr the next day). I could have done it faster on day 2, but it was a PITA to remove the cotter pins."

To remove cotter pins.... From the head of the bolt, rotate the bolt and the nut till you have access to straighten the cotter pin. Then turn the bolt and nut 180 degrees and pull out the cotter pin. This can be done with the bolts fully torqued.

Thanks, everyone, for some pretty helpful advice. I haven't decided to do it ye, leaning in both directions, actually. I'm going to have to make up my mind.

The fuselage is still in the jig. It's an RV-3B fuselage and the jig is essential. I have an opportunity to get the mount finished better than I can do it (the white paint scratches easily) but the only color available is not white, and I like white for this part.

The engine is currently on the mount and the mount's on a pallet/frame assembly. I have a, engine hoist for it if I decide to go ahead. If I do, the engine will go from the frame to the hoist, the mount to the finishers and back, and then everything replaced as they are now.

That is what I ended up doing. Even then, I found it tough getting to get at the lower pins to cut them and pull them. Operator error, I'm sure

Looking at your picture it appears that you are still to drill the legs. If you decide to remove the mount from the engine , then I suggest you fit the mount to the fuse and set and drill the legs. It is near impossible to drill the legs with the engine fitted. Once you have done that you touch up any marks on the mount put it back on the engine and fit hoses and the like without a firewall in the road.
Good luck

Thanks, Steve. It'll be a while before the fuselage is far enough along for that, but that does help with the sequencing of things. I was planning on having the better finish done shortly.
