Hello, I have a Tecumseh av520 engine that needs crank seals I want to do the flywheel side and pto side. Does anybody know the part numbers for these I have looked at some websites but it seems like there is a million different seals, Thanks.
You will also need the spec or type number to narrow down your engine variation. Should be on a tag along with the model number. Depending on year could be a metal tag affixed to the block. Or stamped into the rewind housing or a sticker on the side of the rewind housing
