Excavator Pump Drives: Reliable Torque Transfer for Hydraulic Power

Excavator pump drives couple your engine’s crankshaft to the hydraulic pump, delivering the precise reduction ratio and torque needed for every swing, lift, and crowd movement. When bearings spall or gear teeth wear, you’ll notice cavitation, erratic flow, and dropping pressures that slow cycle times and sap fuel efficiency. VI Equipment stocks complete pump-drive assemblies—housing, gears, shafts, bearings, and seals—engineered to bolt straight in and restore factory-spec torque transfer.

Reman & Brand-New Pump Drives for John Deere, Hitachi & Caterpillar

Whether you run a Deere 210G’s inline drive, a Hitachi ZX350’s offset gearbox, or a Cat 336’s planetary input unit, we catalogue pump drives by model, serial prefix, and OEM part number so matching takes minutes. Reman assemblies are stripped, magna-fluxed, and rebuilt with induction-hardened gears, new tapered-roller bearings, and high-temp seals—delivering OEM torque at roughly 60 % of dealer cost. Brand-new aftermarket units feature forged alloy-steel gears, vitrified bearing races, and multi-lip seal packs, all backed by a 12-month unlimited-hour warranty.

Diagnosing Pump-Drive Wear Before Production Slows

Listen for whining under load, feel for input-shaft play, or inspect case-drain for metal slurry—early indicators of internal gear or bearing fatigue. Rising oil temperature at idle or fluctuating pressure under steady RPM also point to gearbox slip. Capture a quick phone video of the noise or pull the magnetic drain plug for debris analysis and email it to our parts desk; we’ll advise whether a reseal, partial rebuild, or complete replacement offers the best ROI.

In-House Pump-Drive Rebuilds: Precision Machining & Dyno Verification

Our Langley gearbox lab completes most pump-drive rebuilds in five business days. Housings are line-bored to ± 0.03 mm, gears are lapped and checked for tooth-profile accuracy, and tapered-roller bearings are shimmed to OEM preload. Every unit runs on a 200 hp dyno stand where we log input torque, case-drain flow, and temperature rise at stepped loads. A printed performance report ships with each assembly for full traceability.
