How to Buy a Used Wheel Loader: Inspection Checklist
Articulation joints, transmissions, axles, tyres and the loader linkage: here is what to check before buying a used wheel loader, and the test drive that reveals the truth.
Wheel loaders are simpler than excavators in some ways, but they hide expensive components: transmissions, axles and articulation joints. A careful inspection and a proper working test will tell you most of what you need to know.
Paperwork first
- Serial number, year and hours, checked against telematics if available.
- Service history: transmission and axle oil changes are especially important.
- Oil analysis reports for engine, transmission and hydraulics.
- What it did: a quarry face loader lives a harder life than a yard machine.
Structure and linkage
- Lift arms, bucket linkage and pins: look for cracks, welds and play. Raise the bucket, curl it back and rock it.
- Articulation joint (centre pin): with the engine running, steer left and right and watch for knocking or movement in the hitch. Worn bushings and bearings are a significant repair.
- Rear frame and counterweight: impact damage.
- Bucket: cutting edge, teeth and side plates.
Powertrain
- Transmission: shifts should be smooth in all gears and directions. Delayed engagement, slipping or harsh shifts signal problems.
- Torque converter stall test: ask a technician; it reveals engine and converter health.
- Axles and differentials: listen for noise when turning; check for oil leaks at hubs and seals.
- Brakes: wet disc brakes should hold on a slope with a loaded bucket.
- Driveshafts: check universal joint play.
Hydraulics and steering
- Lift and tilt speeds when warm, cylinder drift, leaks and hose condition.
- Steering should be smooth with no excessive play.
Tyres
Tyres can be worth thousands; measure tread depth and look for cuts, sidewall damage and mismatched sizes. Read our OTR tyre guide.
Engine and cooling
Cold start, blow-by, smoke, leaks, radiator and cooler cleanliness, aftertreatment warning codes.
The working test
Load material for 20–30 minutes: watch for engine bogging, slow hydraulics, transmission hesitation, overheating and brake fade.
Browse wheel loader models and compare specs before you inspect.
