Atc125m front sprocket sliding side to side
I just tried to take this motir for a test run and as soon as I put it in gear and started going a lit of oil started leaking from around the front sprocket. I also noticed that shaft will slide side to side like in this video I took.
Is this movement normal? Also, I cant find that seal online anywhere. What is the specific name for it? Thanks!

I'd guess that's not normal. Maybe a spacer or circlip missing inside?

I think I found the seal, sort of. I looked on Partzilla. I looked at the "left cover spacer + sub transmission cover" diagram. I believ it's number 16. Partzilla says that it's "part obsolete". They list the size as 31x43x7. I would guess that means 31mm inner diameter, 43mm outer diameter, 7mm thick. You could probably take those dimensions and find an aftermarket seal somewhere. Hope this helps.

Thank you. I am going to pull the sub trans today and see what else I need. I hope I am just missing a c-clip somewhere on that shaft.

I am missing a c-clip.

The parts missing are 8 and 9. I ordered them along with the oil seal. I hope this will get me going. Can anyone tell me if this seal must be removed through the back of the case where the sprocket is? That would mean I will have to pull the cover off the output shaft.

According to the diagram, it looks like you need to pull the cover off to get the seal out, but DON'T take that as gospel.

I just pulled the cover off and am waiting on parts now.
