I just reciaved my New wear sleeve for the lower seals in the lower crankshaft end cap. The seals are brand new as well. After pressing the sleeve on yesterday I noticed that the sleeve has a vertical or horrizontal indented line that does not run the width of the entire sleeve. I am pretty sure that this is supposed to be there and allows the smallest amount of fuel oil past the inner seal to lube the second outter seal. Am I correct in this assumption? Also I would figure that the best lubricant to put on the seals would be 2 stroke oil. Is this also the best thing to use on them? I have other questions pertaining to cylinder sleeve removal (Tools and proccedures) Were talking limited accomidations to get this cylinder sleeve out without dammage. Also compatibility of two different horse powers being a 40 and a 70 both 1979. The only difference I can see is the 70 has a ported piston and the 40 HP does not therefore the 70 HP cylinder sleeve has a well port cut out and the 40 HP does not have this cut out. They use the same connecting rods and the same ring diameter. I believe thet both have the same stroke ratio as well. I have inserted the piston from the 70 into the 40 HP block cylinders with seemingly the same fit. I can post pictures of this later today.
