Stuck/fused pedals. What’s the solution?

[was8v]

I had a saga like this once, I was most excited until I realised the pedal thread had brought the thread from the crank with it.

Duh. I threw the lot in the bin.

The DMR v8s on the bench were the test. They went in just fine with some grease. Please I am.

I can tell you straight ... this was well worth 14 pages.

Well done.

Judicious application of force - the engineer’s friend

I hate to say I told you so...finally you tried it hard enough!

If it’s steel and aluminum they weld together with time and sometimes they just won’t come loose. The corrosion welding prevents any lube from penetrating. Liberal grease on assembly is the prevention. A weak lye solution is supposed to work on a steel/aluminum corrosion bond but I’ve never had success with this method. I’ve used ultra sound and Blaster, over and over again for days with supplemental hammering and this works sometimes. I once welded in an Allen key because the keyhole was rounded. It came out easily as the heat busted up the corrosion. The problem was that the weld arc vaporized part of the aluminum giving an ugly appearance but it was still functional. I filled the vaporized part with JB Weld and used chrome paint, then clear epoxy. Heat, followed by wet rags also can work as the steam can penetrate. I’ve only used the acetylene torch, wet rag and steam on steel car suspension parts and it worked. Try soaking them all fall and winter as I’ve had a little success here on alloy nipples to steel spokes. Apply new penetrant weekly. How about trying the shipyard last resort to get a stuck propeller off it’s shaft, high explosive. A firecracker wrapped with a lot of tape? I suspect you may be out of luck.

I think you missed the last pages. I won!

climaxing wildebeest…

Yeah, but we're now all wishing the firecracker was attempted before you won.

 

[novocaine]

You have not won. You have mearly delayed the day you come against an immovable object and fail. Fair well good man, for that day will come and it will be a reckoning.
