I haven't seen many of us working on these but I'll ask anyway. I need to build up the pads that contact the valve stems. What is the compound that the rocker arms are made of and what kind of TIG rod should I use to build these up?

 

[lilbill]

don't know about the alloy but the contact faces are hardened.

Welding will not last, need to be hard faced then ground.

Old time fix was build them up with Stellite rod and grind to shape.

 

[S.T.P.]

Don't you weld hardfacing materal onto the piece you are working on?
Seriously I ment to say what kind of hard face tig rod would you use. I've heard a few different things stellite being one. I talked to a Metaleargest/ machinest he said that if it were his he would just run some 312 stainless rod onto it. Also heard manganese bronze would work. I think I'll keep looking for answers for now.

Pan620 where in kansas are you?
Tattoo have you ever priced knuck rocker arms? I have.

yup

+1 on the hardface rod with the tig. Remember to use the least amount of heat possible, 1/8" arc rod uses like 50-60amps. Just clean the flux off obviously first. I'm gonna do my pan rockers soon.

Where are you located in Kansas? I'm in North Kansas City, MO. I have a Cronatron torch setup that uses oxy-acetylene to spray powdered metal and build up a surface. One of the powders is hard facing compound. If you're not close maybe you can find some in a weld shop somewhere local to you. I've never tried it on rockers, but don't see why it wouldn't work.

Wizzbang I'm 30 miles S of Topeka but I'm a local #8 plumber so I'm in KC every day. If I don't come up with something better I'd like to see what we can do.

 

[knuck39]

Keep us posted on the outcome...I'd like to see how it ends up lasting dependent upon what you actually use...

Tig rod - Stellite#6 or Stoody#6

 

[WhizzbangK.C.]

Well, I work 10 hour night shifts Monday-Thursday, and off on the weekends. Maybe we can work out a time to take a stab at it, on a Friday evening possibly?

 

[Early Iron Motorcycles]

Send them to Baisley Hi performance and have them do there roller rocker conversion.

 

[S.T.P.]

Alright, after much research I've concluded that the stellite 6 or stoodite 6 is the right thing to use. Now I'd like to buy less than 5 lbs. I only need a couple of sticks. Does anyone have a few I could purchase?

 

[old.wrench]

That is some mega hard stuff, you won't touch it with a file, must be grounded...

Yeah, it's a little rough on the file teeth .
Even with the right tooling it machines pretty tuff too.
But it grinds very nicely .

Look around for a welding shop that repairs drill bits for the oil patch or a rock crusher .
A welder that deals with heavy construction equipment . They weld wear strips onto the buckets of loaders and backhoes .
A place that builds teeth for farm tillage tools chisel teeth, cultivator sweeps .
Hope that helps you find some rod. Good Luck on your rebuild.

 

[S.T.P.]

The rod they use on heavy equipment is not as hard as stellite #6. Nor is it as resistant to metal to metal contact.
