Service jobs and parts
Engine oil and filter change

Known problems
Drum brakes need wheel cylinders
The Mule SX and 600/610 use hydraulic drums. Kawasaki asks for wheel cylinders and master cylinder seals every 2 years.
Two front oil sizes
The Mule SX 4x4 front final gear takes 0.35 L but the older Mule 610 takes only 0.2 L. Fill to the bottom of the filler opening.
High altitude
Kawasaki says the belt converter weights need changing by a dealer for use above 1,500 m.
Repair guides
- Drum brakes: pedal play, fluid and the 2-year seal renewal (Specialist, 15 minutes for owner checks; dealer for linings and cylinders): Pedal travels further than it used to, feels rough or catchy, brakes pull or grab, or the fluid level drops.
- Flat battery: electrolyte, sulphation and slow charging (Easy, 30 minutes plus charging time): Slow cranking or nothing on the starter after the Mule has stood, battery will not hold a charge, or the electrolyte is below the lower line.
- No power or belt slipping: converter water, dust and drive belt (Specialist, 30 minutes for owner checks; dealer for the belt and pulley): Engine revs but the Mule is sluggish, especially loaded or uphill; slipping after deep water; or a burnt smell from the belt converter.
- Starter will not turn, or engine cranks but will not start (Easy, 30–60 minutes): No response on the key, starter clicks, engine turns but will not fire, or it stops and will not restart.
- Steering play, joint boots and wheel nuts (Easy, 30 minutes): Vague or notchy steering, knocking over bumps, split rubber boots, or a wheel that has worked loose.
