G'day all,
I've come to a standstill with my T5 conversion.
Some of the bearing faces on the input shaft have breakages in the machined surfaces. They cant be felt with a finger.





I am thinking that i might be able to skim a couple of thou off the worn surfaces, build back up with powder spray, then re-linish to size.

Has anyone done this, or is there a flaw in my cunning plan?

I have full access to a machine shop, & am currently chasing down contacts in the metal spraying game, so the labour content will be minimal. Certainly cheaper than spending $400 on a new input shaft.

I damaged the front of a crankshaft when the harmonic balancer worked loose and had it repaired this way.

It was 100% successful.

Cant see why it wouldnt work for your application.

Like this,but different.

metal is applied using a fine tipped heating torch with a hopper on top. Similar to a gravity fed spray gun.

The metal is in powder form.
Preheat the item, rotate at a constant speed, apply the spray powder with concentrated heat.

My concern is that the preheat might be above the plastic limit of the parent metal.

Kinda like a one-step Powdered Metallurgy process, cool. Cheers!

I have considered shrinking a bronze bush in the internal.

Wonder if that would work on the flange...
