Chainsaw Repair

I have one of those type saws with a lot of time on it.

If the bearing gets bad, the clutch drum will occasionally make a ding sound at idle.

The shaft is as hard as the bearings. I doubt it is worn? Get a new bearing at the Dolmar dealer. Be careful, there are two different bearing sizes in those saws. You will have to take your old bearing in with you. The clutch drum may be worn? You could try a new one but there are two different sizes to match the different size bearings. The later, bigger, bearing lasts longer.

The shaft is the crankshaft. The chainsaw will have to be taken completely apart to to change the crankshaft$$$$$$

+1 on the above. If the bell and bearing are both worn and not the crank, I would replace the bell and the bearing with the larger bearing and matching bell.

Put some grease or oil on it when you put it back together. As you use it the chain oil will keep it oiled.

Use the saw when you need it for now.

The two bearings had the same inside diameter but the newer larger bearing was bigger on the outside. Apparently they had trouble with the original bearing?

The new bearing has larger needles. There are fewer needles and a more sophisticated cage.
