Steering rocker shaft - chemical rebuilding

Hoping someone with a worn sealing surface and a lathe will try rebuilding with Loctite Fixmaster metal rebuilding product.

Steve, Looks like good stuff. Do you think it is any different that JB Weld? I onced fixed a cylinder head on an MG Midget some 25 years ago with JB Weld. I know the car and owner and it is still on the road with no additional repairs. But I must say that the repaired area was not subject to movement or a rotating force such as a running shaft on a seal. But it was on the underside of the head right next to a combustion chamber. I meticulously filed the profile so the combustion chamber would seal.

Don't know about JB Weld for that. Would it contain enough steel to be properly hard against the wiping of the seal. The Loctite product is made for this use.

In the past, I'd seen something about this Loctite product being used to repair large shafts in place, maybe at power plants or pumping stations.

One's lathe would have to have the ability to grip the rocker shaft with the rocker inside the chuck. Or maybe one could make an extension to grab the threads so that one could turn down the affected sealing area and install the product, then turn it down to the original specs.

Surely once one got the surface properly finished, the action of the steering seals would be fairly low-stress compared to a whirring shaft on a pump.

I just got an email response from one of my esteemed colleagues who noted that JB weld will withstand up to 500* and this stuff not near that amount. Maybe that's why the JB Weld worked on the cylinder head.
