I have a older Cushman Frontline mower that was given to me 4 years ago because the engine was ready to calve.It has blow by and it overheats or at least bubbles coolant and it seems to be coming out the crankase vent sometimes too(steam) so I suspect a head gasket(?)
Being cheap,I ran the engine 4 more years but pulled the engine a couple days ago to do an overhaul.When I call the dealer,he can't seem to figure out the engine model or even the make but suspects it is a little Mitsubishi diesel.
The model of Cushman is a Frontline 898804 and it was built sometime in the early 1980's.I wouldn't mind putting a few bucks into the machine because it's fast and spins on a dime which comes in handy for the 25 fruit trees in the yard.We had a 42" Craftsman but it took 3 hours to do our whole lawn,it's half the time with the Cushman.
Here are some pics of the 2 cyl diesel engine,first one shows the bottom of the crankcase
This second pic shows the back side of the engine with the injector pump.Notice the radiator is mounted directly to the engine.
And the front.There is a rubber damper that bolts to the flywheel to connect to the hyd pump.
Can anybody point me in the right direction for engine parts(rings,gaskets,manual etc)?
