need a camshaft for a 82 yamaha seca 400cc xs motor.
 

So i sold my 1982 yamaha seca that had a motor problem i did not know it had a brookin cam shaft. the guy i sold it to was a ex harly tech that now is a sub teacher. he was the coolist guy i have met in a long time
and i would love to help him fined one. so i reach out to you guys to help us. that motor was only made for two years so it is hard to fined.
he found one in ohio but he would like a better price. I dont know the price he found.

thank guys

Can the cam be welded and turned? Know anybody with skills and equipment like that?

I don't.

Not sure on this piece but if it's cast iron and broken in two good luck!

Although I think the Jap's did like steel, but even still I think that would be difficult to do.

You can't weld a cam, just not gonna happen.

Ok, didn't know.

I know that some cam grinders have welded the lobes to subsequently grind a new profile, but I wasn't sure if a broken shaft could be repaired. BTW, I've read that the Japanese have excellent quality steel, rivaled by the Swedish.

Might be pricy but have you looked on bikebandit?

I didn't work on enough Volvo's to get a feel, but the Japanese steel parts were always quite nice...made pretty sparks. On the flip side, Dodge had some really ugly looking steel pieces and could be like taking your life in your hands picking them up without gloves.

D, you're correct on building up a lobe. It is much like crankshaft welding where if the journal is chewed down below bearing sizes you can weld the journal back up and regrind it to spec.. but if the shaft was in two pieces or even cracked, no go, it's in the scrap heap.
