Montgomery Ward chainsaw (TMC24060A - 88cc)

Crank bearings are needle type with separate thrust washers. Check your crank play. Should be no up and down and a little side to side. I haven't generally found rod bearings loose on these saws. They tend to be understressed. For the case orings, just clean everything up and coat them with motoseal or yamabond or Hondabond or a gas safe sealer and reassemble.

That muffler may require a spacer like here.

Ok, I was looking online for a while and I can't seem to find anything on the crank bearings or crank seals. The bearings might be okay, but I'll need to replace the seals for sure. Any ideas or sources for seals?

I'll keep that in mind for the o rings. I'll be careful removing them. I've heard good things about Yamabond. Maybe I'll give that stuff a try.

Did some digging online. Found a guy would went through a Remington Bantam and rebuilt it. He had some part numbers up there. His used the same crankcase as mine (35254). I'm assuming it would also use the same crank bearings and seals.

Crank bearings are Federal Mogul SCE 1211
Crank seal (flywheel side) is SKF 7443

Unfortunately he didn't list the clutch side seal part number. I'll have to do some more research on that.

Seals are CR9838 and 7443. Common sizes.

Great! Thank you!

Another question:

Should I attempt to clean the original cylinder and install the used Ebay piston/rings/rod into the original cylinder? Or should I just use the Ebay cylinder with the Ebay piston/rings/rod so it's all matched up?

Only downside I can see to using the Ebay cylinder would be the paint color would be a little different.

I'd rather not take the rings off of the piston as if they break I'm screwed. I can't seem to find any used or NOS rings on Ebay. Was hoping I could just toss the Ebay cylinder/piston combo into the saw, button it back up, and call it a day. While I'm at it I could install new crank bearings and seals, etc. Just wasn't sure what route would be the best for the cylinder.

That will depend on how your original cylinder looks when you disassemble it. My inclination it to keep as many original parts as possible
