Old Mule 2010 Oil Change Help

Recommended Posts

I have a 1990 Kawasaki Mule 2010 (KAF540C) with 535 cm3 air cooled single cylinder engine. Need help locating the oil fill location, dipstick location and drain plug location for an oil change. Was told that the engine oil and rear differential share the same fluids. Is this correct? Found the rear end fill plug, sight glass, and drain plug, but the level in the sight glass is several inches below the engine crankcase. How can there be any oil in the engine if the oil level is lower than the engine? Please help! Bruce

That's what they call an "Oil pan" the pump sits down in it and the pump pumps the oil through the oil passages, the entire engine (Crankcase) is not filled with oil.

Sounds like you need an owners manual. If you plan on working on it yourself, then maybe a shop service manual.

My mule is a diesel model, from a different year, so my information wouldn't help. But the oil drain can be found on the bottom of the oil pan. Mine is hidden by the skid plate. The dip stick, and the filler cap should be topside.

No, rear end and engine oil fill isn't the same.  Pick up the seat and look for  a round plastic plug probably 4 inches around. Pop it out and you will see a dipstick, it has a rubber end, pull it out and that is where you put the engine oil in. The drain plug or plugs are under the engine. You can remove either one and drain the engine oil. You will have to jack the mule up. I put mine on jack stands for better viewing. You will see the oil filer in front of the engine and the oil plug is in the general area to the side or below. I cannot remember at the moment. But, no, engine and rear end oil aren't the same on the Mule. Most of the smaller 4 wheelers are, but not the Mule.  Hope you didn't get this to late.

      Once i get the cylinder honed, the only remaining problem is the crankshaft shim..  And i have a few questions.
      1. In the manual it gives a solution to the problem i'm having of the crank NOT spinning when the cover on (by hand).
      2.  And i just can't wrap what's left of my brain around the instructions, i guess use a caliper to measure? (instructions  circled in red)
       (my brother has been helping me, he's fairly knowledgeable with this stuff, but more Diesel engines than anything) and he says to use a dial indicator set up, and to use this* as a spec for end play. and that would help us get the measurements needed in picture #2.
      1st pic is the runout. But is it the same as crankshaft end play? 🤔

      2nd pic is of the instructions (solution) to get the correct shim.
       I don't know, maybe this makes sense the way i wrote it.
       Thanks, Travis.

      Hello everyone. I’m looking into getting a UTV to mainly use at the hunting lease. Need to be able to haul around gear and decoys and at least one dog kennel. Would also like to use occasionally around the neighborhood (Golf carts and UTVs are allowed in my area). I know I want a 4x4 and don’t necessarily need something that’s gonna go 40-50 mph.  I’m an engineer and enjoy maintaining all me vehicles/ toys so I can give something a once over and notice any glaring defect but I have a few UTV questions  
      Is there anything I should watch out for? Any specific questions I need to ask the seller? How many hour/ miles is too many? I want something used but not used up. Anyone feel their UTV has been underpowered- should I get at least a YYY cc engine?
      Theres a 2014 Kawasaki Mule 4x4 XC with a nice 5x10 trailer for sale that I’ve been eyeing, anyone have good/bad comments about this particular vehicle?
      Thanks!!

      Hell to the group. I am new to the forum and have been searching everywhere for some information about the KAF950 engine. I have 2 of these engines and I am wondering if there is any performance upgrades that can be done to these engines relatively easy. I dabble in the metal fab worl and I really enjoy build rat rods and such. I plan on building a rat rod style trike and I am wanting to use one of these engines as the power plant. The engines I have are the older mechanical style no computers or any of that. Any tips and info will be greatly appeciated.
      Thanks!

      I've got a 2006 mule 610 4x4 that was inherited by my wife. It has 1300 hrs on it & was in pretty bad shape cosmetically. It did however run but was hard to go into gear. It never seemed to get up to max speed.
      I cleaned it up & replaced a few plastic parts, seat covers plus the front mounted winch. It ran for a few miles, then when I stopped & put it in reverse it would not move. You give it gas & it seems like it has the brake on.
      I pulled the primary cover off & the primary clutch turns but the secondary clutch will not move when you try & turn it by hand.
      Any thoughts?
