Probably need a motor

Post by timsresort » Sun Nov 18, 2018 8:43 pm

Helping out a friend with his mule of about 20 years. He tells me he hasn't run it in a number of years, and when he did, it was leaking fuel out of the bell housing. So I bought and installed a fuel pump, drained the oil and filter, which was full of fuel. Put it back together, started right up, ran for a few minutes before bad metal on metal noises started. Shut it off. My take is he probably ran it too long with thinned oil and did bearing damage, which led to low oil pressure, and lost the motor. Sound plausible? Does it make sense to rebuild? Or is a new 2A042 generator motor more time and cost effective?

To me, the 2AO42 gen set engine is the best option, you get everything new. Saturn Surplus still has factory fresh gen set engines for $650., but you better hurry, they will be closing Dec 31.

If the oil pump failed or had low output along with diluted oil then the damage starts with the rod bearings, then piston skirt skuffing, then possible front camshaft bearing spinning and ect.

My opinion: use the 2AO42 powerplant engine. You get a new long block instead of a rebuilt mule block with unknown hours and damage. The cost of replacing cyls, pistons, rings, rods-bearings, crank, cam, oil pump plus G/S set and time will equal or be more than the powerplant or genset engine.

I have the genset engines in stock plus all the parts to rebuild the your mule engine if you choose.

Pics of the genset engine I converted to a mule engine. I cut off the oil filter mount from the timing gear cover to eliminate removing it and replacing with the mule timing gear cover. Saves time and a gasket/seal.

Contact me via E-Mail see Contact Info for further help or parts.

I installed NOS or NEW mag, governor, carb, ignition cables, spark plugs, blower, fuel lines and a rebuilt original fuel pump.

Thanks guys! I think I will pursue the generator motor. As I've seen on here, maybe mount the old and new on stands and move parts over. Sounds like a fun winter project.

Having them side by side when you swap parts would be helpful with the shrouds. They are kinda of a puzzle. Not crazy difficult but just moving from one to the other would make it easier.
