I've got a couple of 668 heads, old dirty and a bit corroded, that I can't get the cam follower buckets out of. In the other heads I have got them out of it normally requires the removal of the burr caused by cam wear in the journal, and once cleaned up, with plenty of Inox and movement, and rare earth magnets, I can get them out.

But these 2 heads, short of welding nuts on the top of the cam backets, I can't think of any other way.

Any tricks?

Regards, Greg

 
Can't get air pressure under, the stud welder may work, but will destroy the buckets as per my idea of welding on nuts, rare earth magnets are a lot stronger than a valve lapping suction cap.

Heat, and differential expansion. Haven't tried that. Missus hates it when I bake engine parts in the oven, makes it smell. Oh well, here we go again.....

I have a heat shrink tunnel here at work, you are welcome to bring them over and we can wack them in there without the belt running, can get it to 200c.

If we pull them out of the tunnel, once cooked, and then use a blast of compressed air onto the buckets and use the magnet to reef them out. Worth a try, better than having your Mrs on your back.

I will be here Saturday or Sunday sometime as well, pulling my forks apart, ready for the Snowy.
PM me if you wish.

How does oil get in and out?

Hmm ?  Thinking about it has me wondering how pneumatic valves get oil to the valve guides.

If you have the space in your shed, it might be worth scrounging an old stove that has a working oven.
