McCulloch Chain Saws

There is no such thing as a donor Mac - get em both running!

I am a proponent of the Viton fuel tank gaskets. I have had several problems with new (NOS) cork gaskets leaking and zero issues with the Viton gaskets on any saw with a full channel for the gasket to sit in.

The flywheel side bearing is supposed to keep the crankshaft from moving laterally in the saw, there should be a retaining ring on the bearing that fits a groove in the crankcase halves. If the bearing fits the crankshaft properly it cannot move in the crankcase.

The spacer washer between the oil tank and the gasket (69772) is normally a fiber washer, I have them in good supply.

I picked up a 595 recently. I believe this is the European equivalent of the 550 Super? It appears to have a “Super” piston and rings. I measured the bore as best as possible and it appears to be 56.6mm. The saw also came with a parts diagram. It has the piston part number listed as 62883 with rings 62422. The saw has some good bones with the exception of a broken lower handlebar mount. It definitely bothers me I think I will have to swap it out. Parts diagram has the fuel tank listed as 62154A. Would this be a common part?

I'm pretty sure that tank was also used on the US version of the Super 250, 550, and later production 450 saws. The 380A and early 450 saws also had a pulse operated automatic oil pump built into the fuel tank but it was a different design.

62883 is a thick ring piston and is also called out for the 790/795 890/895 models saws (2.211/2.210"), I have a few NOS piston assemblies (piston, rings, bearings). My inventory says I also have a few 62154 tanks if you are interested in either. As you know, shipping to Canada is more expensive.
