Metal spraying

[Spark plug]

I'm helping a friend fettle up his newly acquired layland 255 tractor. The steering is dreadfull even by old tractor standards.

On investigation the steering centre pin is badly worn causing lots of play and also stopping the power steering working properly. New pins are available but are expensive so looking for a cheeper solution.

The worn area needs building up by about 0.011" at the worst part to 2" and the area is aproximatly 3" long, obviously requiring machining after.

Anyone got any idea what this world cost?

This is a very common problem, have a look on here to see what's typically done: http://leyland.conforums.com/index.cgi
I think the thread you need to find is on Nuffields so bear that in mind when searching.

Nice tractor the 255 btw

Hear is the pin in question:

It's worn bettwen the underside of the circlip grove and the start of the taper, it has two BX type split bearings running on it. I could turn a new one but realy it should be heat treated then ground after to get a good fiton the taper.

Sold a flame welding torch and a load of powder to a member from here yesterday, and powder welding and grinding to size would be perfect way to repair that. Some of the powder was used to build up worn rail rolling stock wheels, and might be ideal for your repair?

Can you not just protect the tapers, build the worn area up with weld, then remachine. Sure you could do it with some kind of hard rods and a stick welder.

It would work but welds would effect the existing heat treatment.

Or machine a new one of course. How much is the new part?

I have used the above in the past for parts, They used to do "used" parts, but the prices were vey reasonable.

Have you popped into your local AGI services and asked if they have pattern parts? Or advise on breakers. Down here we have 2 tractor breakers.
