This question relates to the installation of crankcase oil seals in a 2 stroke engine, but I thought there would be knowledge available from members of this group.
I’m replacing a damaged oil seal behind the flywheel of my ‘78 Yamaha DT175E enduro bike. Took it apart, ordered a new seal and but read on line that I should be reinstalling the oil seal with the lip facing outward and the “flat side” towards the crank bearing inside the crankcase. Now this has
thrown me off because I’ve never installed a crankcase seal in that orientation. I’ve always positioned the lip of the seal inward towards the bearing (with the seal spring located inside the crankcase). The seal I removed had the flat side with the numbers and markings facing outward.
I’ve attached a picture of the old oil seal beside a new one (the new one is a camshaft seal, for the 650) for reference.
Please let me know what you know about this. Thanks
