Al and Ethan successfully removed the clutch assembly from the Ruston Crankshaft.

Removal of the flywheel, however, is another matter entirely. We are thinking we will support the crankshaft with roller assemblies that the machine shop uses for monster work (like polishing our 8 foot Atlas crankshaft!).

we can spin it and polish it on the concrete pad, and check for straightness.

In the meantime, I will pick up the clutch assembly for cleaning / sandblasting / painting / and re-assembly next time I'm at the museum.

I tried Ironworker's method of trying to pull the key out, still to no avail. Even with tension on the puller, heat from an o/a torch, and a slide hammer on the end of the puller bolt, it doesn't want to budge. The weather has not been kind to this engine! I think i'll end up drilling this key out if it doesn't move after a couple more attempts.

One possible way to remove that key is with a modified slide hammer. I have a2 cylinder Straubel inboard ca.1910 which had a 1/2" key which had defied all attempts using wedges and scimitar shaped wedges all to no avail. I drilled and tapped a 3/8-16 hole and used a conventional slide still no luck. Talked to a friend and got his slide hammer which was a piece of 5/8-11 threaded rod with a short coupling nut which was threaded for 5/8-11 on one end and 3/8-16 on the other end . I used a short piece of grade 8 3/8-16 about 1.5"long which threaded into the key and coupling nut snug. One wack withe the slide and the key came out. My first attempt using a long piece of 38-16 threaded rod was simply a high rate spring and all of the slide hammer went into the spring and not into the key.

Hope this works for you

Dick

Unfortunately this key is about 1/2 x 1/4" cross section, so that leaves very little meat to drill and tap a decent size hole. I was messing with it today, and broke off the stub that i welded on for the bolt puller. I think the next step will be to drill the key out and hope that it collapses enough to let the cam off the shaft.

I have successfully removed 1/4" keys using 10-32 grade 8 and making a special coupling nut.

Cheers

Dick
