Hello all,
I have aquired a Suzuki SP370 and have found that the cylinder head is worn on the inner camshaft bearing surface and the camshaft is worn also at this point of contact, possibly caused by the timing chain being too tight and dirty oil. The other bearing surfaces are fine. The cam runs directly on the bearing surface of the alloy head and not on any removable bearing/bush.
It is funny that the camshaft being made of steel is worn as well as the aluminium bearing surface.
I am thinking of building up the worn part of the cam with weld and then machining to a determined size on my lathe.
Clamp the head onto the compound slide and fly cut the bearing housing between centres oversize to suit the built up cam.
My question is what type of rod/ wire should I use to build up the camshaft bearing in mind that it runs on oil on an aluminium surface and that I would like to turn it down on a lathe?
I have also considered building up the aluminium bearing surface and machining back to standard but I don't have the suitable equipment.
Any thoughts/comments would be appreciated.
Cheers
