Oliver 1655 pto leak

Josh in Pa · Mar 9, 2019

I have a 1655 that leaks around the pto shaft. When I take out the snap ring and pull the pto, maybe a cup? Of gear oil runs out. The o ring around the bearings could stand to be replaced, but I thought it should be dry behind the pto shaft? I can see that it does have the plastic plug in the back of the gear. Is there a seal leaking oil? Maybe that plug? Or is there some oil in there and the o ring around the bearing keeps it from dripping? It doesn?t drip a ton, but getting it ready to paint and this is one last annoying drip.

I have found 2 sources: 1. the seal behind the spanner nut. #30 on the parts breakdown. My 1650 didn't have that in there. 2.) the cap at the end you referenced. My 1650 didn't have one at all and my 2-70 I just bought the cap is cracked. The 2-70 has the same deal you are talking about and this summer I'm pulling it and replacing the cap. The 1650, I put a new cap on it first, still leaked, put the seal I talked about in, still leaked, now have figured out that it is leaking around the cap that I put in.

Not sure how to keep that from leaking, but I filled it with RTV, put the snap ring on it, and it's still there, but leaking... Another time.

Long winded answer to check the cap and the seal.

Got it apart and the cap is cracked. Going to do the seal too. But I think it?s mostly coming thru the cap.
