Repair a First Motion Shaft for a Austin Healey 3000

[racerbuff]

[h=2]New member so I apologize in advance for duplicating this thread. I just did not know where best to place it.[/h]

Badly need a usable first motion shaft for my 1964 BJ8 Centershift case. Or if anyone knows someplace that can repair the damaged syncro friction surface???
Is it possible to weld and regrind?

thanks,

There's a substance that Loctite makes for refurbishing seal grooves on power plant turbine shafts. Evidently you apply it on a lathe with a squeegee, then after it hardens, turn it down to size. If it'll work there, it'll probably work on the first motion shaft. Google to find this. I don't have any other info.

I was originally interested in it as a solution for worn-seal grooves in our steering shafts.

I suggest you contact local machine shops about who can/does flame spray build up of crankshaft journals. It is quite likely that they could turn down the damaged surface on your input shaft, build it back up with flame spray, then grind the correct profile back for the synchro seat. It won't be cheap but it will be metal on metal and most likely... have a hardness similar to what the original surface was.

I wonder if a speedy sleeve will work for that? I've used them in the past on my 50 Plymouth for the front crank seal, they work great.

Thanks, I am heading to Seattle Autosports (British specialist machine shop) this morning and will report back on my progress.

thanks but thinking this would be a reach to find a sleeve with correct taper and diameter. Hoping I can get it welded and reground.

In the past we have used two small seals to replace the original single one which by passes the old shaft's grove.???

Buff,

Did you get your shaft repaired (I need some work done on mine)?
