| Part | Qty | Notes | Part number |
|---|---|---|---|
| Air filter | 1 | Genuine Suzuki number; fits KingQuad 500 and 750 from 2011 (Suzuki US parts store and dealer catalogue) | 13780-31G30 |

V-belt (CVT) inspection
Transmission · every 1,000 km or every 3 months
Suzuki's chart says inspect the drive belt every 1,000 km (600 mi) or 3 months and marks it R (replace) in the 2,000 km / 6 month column. Suzuki marks belt work as a dealer job. The belt runs dry; water and dirt in the cover wear it quickly.

- Remove the outer belt cover as the service manual shows and check the belt for cracks, glazing or wear.
- The belt cover has a water drain plug: drain any water after wet work.

Front and rear final gear oil change
Transmission · every year
Suzuki's chart says inspect both gear oils every 2,000 km (1,200 mi) or 6 months, replace the final gear oil every year and the front differential oil every 2 years. Both are done here every year. The rear case also serves the sealed oil-bathed rear brake, so use the oil the handbook names (Mobil Fluid 424 or equivalent).
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Front differential oil | 1 | SAE 90 or 80. Check your handbook. Suzuki Hypoid Gear Oil is sold for KingQuads. Aztec Oils match: TRANSMATEC EP-4 90 | check your handbook |

Step-by-step
- Ride first so the oil is warm, then park level with the engine off and key out.
- Drain and refill each case with the oil and quantity your handbook gives, using new sealing washers.
- Milky oil means water is getting in; have the seals checked.
Tools: Drain tray, Socket set, Torque wrench, Oil pump or squeeze bottle
Coolant check and change
Cooling · every 2 years
Suzuki's chart says replace the engine coolant every 2 years and inspect the radiator hoses every 2,000 km or 6 months. The system holds 2.5 L.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Coolant | 1 | check your handbook | check your handbook |
Step-by-step
- Never take the radiator cap off a hot engine: coolant can spray out and scald.
- Top up through the reserve tank to the upper mark with the coolant your handbook names.
- Clean mud off the radiator with low-pressure water. Coolant is poisonous to animals: dispose of it safely.
Tools: Funnel, Antifreeze tester

Known problems
Service reminder needs resetting
The display shows a spanner symbol when a service is due. A dealer says the reset needs Suzuki's plug-in tool (which bridges two wires in a connector disguised as a relay), so ask your dealer to reset it after each service.
Three spark plug heat ranges
Suzuki's parts catalogue lists LMAR6A-9, LMAR7A-9 and LMAR8A-9 plugs for this engine. Fit the one your handbook names for your climate and use.
Water in the gear cases
Owners who work on wet ground check the differential oil for milky water contamination; change it straight away if it is milky.
Sealed oil-bathed rear brake
The rear brake runs in oil inside a sealed case, so the right oil and an intact seal matter. Use only the oil your handbook names for the rear case.
Repair guides
- Service reminder spanner light will not go out (KingQuad 500) (Specialist, 15 minutes at a dealer): The spanner symbol stays on the display after you have done the service yourself.
- Spark plug choice, fouling and misfire (KingQuad) (Easy, 30 minutes): Hard starting, misfire at low speed on light farm work, sooty plug, or a plug that looks white and overheated.
- Milky gear oil and drive shaft seal leaks (KingQuad) (Moderate, 1 hour for oil; 3–5 hours for a seal): Milky front differential or final gear oil after wet work, oil on the inside of a wheel, or a weeping seal at a drive shaft.
- Sealed oil-bathed rear brake: wear check and plate replacement (Hard, 3–5 hours): Rear brake or parking brake weak, wear indicator outside its range, oil leaking at the brake case, or plates due at 10,000 km (LT-A450X).
- CV boots and drive shafts (Yamaha and Suzuki) (Hard, 2–3 hours per shaft): Torn boot with grease flung round the wheel arch, clicking on full lock, knock when taking up drive.
- Wheel bearing check and replacement (Moderate, 1.5–3 hours per wheel): Wheel rocks top to bottom when gripped, rumble or growl that changes on turns, uneven tyre wear or a hub running hot.
- Ball joints, tie-rod ends and toe setting (Moderate, 1–2 hours per side): Steering wander or knock over bumps, play when you rock a front wheel side to side, split rubber boots on the joints, or front tyres scrubbing.
- Disc brake pads, discs and caliper slide pins (Moderate, 1–2 hours per axle): Grinding or squeal, pads down to the wear grooves, lever travel growing, brake pulling to one side, or a caliper sticking and the wheel running hot.
- Recoil starter rope and spring repair (Moderate, 1–1.5 hours): Rope snapped or frayed, rope will not rewind, or the pulley spins without turning the engine.
- CVT drive belt inspection and replacement (Hard, 2–3 hours): Jerky take-off, slipping under load, burning smell, squeal, loss of top speed, or a belt that is cracked, glazed or narrowed.
- Overheating: cooling fan, radiator and cap (Moderate, 1–3 hours): Temperature warning light, coolant boiling into the reserve tank, fan not running when hot, or (TRX350) oil running hot with the oil cooler fan silent.
- Winch will not pull, runs one way only, or runs weak (Moderate, 1–2 hours): Nothing happens at the switch, the winch only runs in or only out, motor hums but the drum does not turn, slow line speed, or the winch got soaked.
The full step-by-step guides are in Farmyard Workshop once you add your quad.
