Kawasaki Mule 3010 4x4 (KAF620E/H)
2001-2008 4WD utility workhorse powered by a liquid-cooled 617cc V-Twin gas engine with dual-range CVT transaxle.
Quick-Glance Shop Specs
Full Matrix ↓The CVT air duct intake under the seat routinely sucks in fine dust and dirt, rapidly wearing clutch sheaves and the drive belt. Check the duct clamp and filter screen religiously. In cold weather, carburetor icing or pilot jet varnish can mimic fuel pump failure.

Common Issues (3)
Kawasaki Mule 3010 4x4 (KAF620E/H): Machine won't move or slips severely under load with high engine RPM
Root Cause: CVT drive belt worn past service limit (width under 27 mm), glazed sheaves, or stuck drive pulley weights from dirt intrusion.
Shop Check: Remove CVT cover, measure belt width; clean sheave faces with Scotch-Brite and alcohol, blow out clutch dust, and replace drive belt (59011-1057).
Kawasaki Mule 3010 4x4 (KAF620E/H): Engine cranks strongly but starves for fuel under load or dies after 10-15 minutes
Root Cause: Failed impulse/electric fuel pump, clogged tank vent, or restricted barbed inline fuel filter.
Shop Check: Verify flow at carburetor inlet. Test fuel pump delivery rate (minimum 3.4 oz/100 mL in 15 sec) and replace inline barbed filter with WIX 33032.
Kawasaki Mule 3010 4x4 (KAF620E/H): Engine runs hot, temperature light illuminates, coolant boils into overflow bottle
Root Cause: Radiator cooling fins packed with grass chaff or mud, cooling fan thermo-switch failed, or air locked in cooling jacket.
Shop Check: Gently pressure-wash radiator from the back side, test fan switch jump-to-ground, and bleed cooling circuit using the thermostat housing air bleed screw.
