Used Volvo Wheel Reducer

Volvo Wheel Reducer: Torque Multiplication Near the Wheel

On a Volvo axle, the differential distributes torque to both sides; the wheel shaft then delivers it to the hub. The Volvo wheel reducer, housed within the hub, multiplies this torque via its planetary gear set. This design lightens the shafts and axle, allowing them to operate at higher speeds with lower torque. On many loaders, the reducer, hub, and brake form an assembly whose reference depends on the front or rear axle.

Volvo Wheel Reducers by Machine Family

• Wheel Loaders: the most common, ranging from L45B to L350F.
• Articulated Haulers: series A20 to A40, on each axle.
• Wheeled Excavators: EW160D and EWR150E.
• Backhoe Loader: BL71.
• Older Volvo BM Models: 4500 loader, 861 and 5350 articulated haulers.

Tracked Volvo Loaders from L45 to L350F

Our stock covers a wide range of Volvo wheel loaders: L45B, L70 and L70F, L90C, L90D, L90E and L90F, L110E, L120, L120E, L120G, and L120H. Larger models are also available, from L150C to L150F, L180, L180E, L180F, and L180G, up to L220E, L220G, and L350F. Between series, for example between L120E and L120G, the reducer’s ratio or mounting points may vary. The reference stamped on the housing and the loader's serial number verify compatibility.

Volvo Articulated Haulers A25 to A40 and EW Excavators

• A20 and A25: A20, A25, A25C, A25D, and A25E, front and tandem axles.
• A30: A30D, A30E, and A30G.
• A35 and A40: A35D, A35G, A40D, and A40E.
• Wheeled Excavators: EW160D and EWR150E, front and rear reducers.
• Points of Attention: hub seal, bearings, oil condition, and metal particles on magnetic plug.

Reducer, Hub, or Axle Nose: Diagnosing the Fault

A noise matching wheel speed and leakage near the rim point to the reducer or hub seal. Clicking during turns or noise centered on the axle suggests the differential or the Volvo axle nose. Before replacing the reducer, check the Volvo wheel hub and its bearings, as well as the splines on the Volvo wheel shaft driving it.

Preparing a Request for a Volvo Wheel Reducer

• Loader or Hauler: full designation, series letter, and chassis number.
• Axle: front, rear, or tandem for haulers.
• Side: left or right, specify even on symmetrical axles.
• Marking: Volvo reference on the housing or cover.
• Equipment: with or without integrated brake, number of wheel studs.

Installing a Wheel Reducer on a Volvo Machine

Clean the axle seating surfaces and replace the hub seal if it has leaked. Fill the reducer with Volvo-specified axle oil, positioning the plug as indicated in the manual, then check the level after initial operating hours. Torque wheel nuts to specs and retighten after a short operation period. For all axles and gearboxes, see our Volvo transmission page.

Front, Rear, and Integrated Brake Reducer Versions

• Front or Rear: two reducers of the same machine may look alike, but mounting points, sensors, or housing can differ between axles.
• Integrated Brake: on several loader axles, oil-bath brake discs are located near the hub, altering the assembly’s reference.
• Tandem Haulers: the two rear axles have distinct reducers different from the front axle.
• Wheeled Excavators: the front steering axle and the fixed rear axle don’t always use the same reducer.
• Do Not Confuse: the gearbox upstream in the drivetrain sets the gear ratio; the wheel reducer multiplies torque at the end of the chain.

Overhaul or Used Volvo Wheel Reducer

An overhaul requires removing the hub, opening the planetary gear set, and replacing worn satellites, bearings, and seals. As with gearboxes, the repair bill often depends on teardown inspection revealing the true condition of gears. An original used reducer, dismantled from the same Volvo series machine and workshop-tested, installs directly to replace the old one without waiting for spare parts. Your machine is back on site sooner with a part designed for its axle.
