I have a 1991 LX186 with the Kawasaki FC540V AS10 engine. It is leaking oil from the crankcase gasket behind the oil filter and I need to replace it. In trying to locate a gasket, I keep getting two different part numbers, depending on source. One is M143232 and the other is M143234. How do I know which one I need?
In addition to the gasket, I know I also need the crankshaft seal that goes onto the crankcase cover. Is there any other parts I need to do the job that I am over-looking?
Thanks for the help.
