Trying to find a part number for the gasket that is between the oil tank and chain case cover . Had the whole assembly off the sled this summer and when I put the chain case cover back on and refilled the sump with engine oil it was leaking all over my shop floor. Upon inspection a fairly steady drop was coming from the bottom of the oil sump between the sump and the chaincase cover. I took the cover for the sump off and inspected it for cracks but it is fine. I think the gasket may have dried up a bit over the summer. The weird thing is I have never separated the sump from the chain case cover so was surprised to find that it was engine oil that was leaking and not chain case oil. Chain case was torqued properly to spec as well. Anyways I cannot find the gasket that fits the profile of the sump. It's not in the chain case assembly or the oil tank assembly fiche either. Dealers around here don,t know where it is. Anybody actually replace one of these?
