Excavator Planetary Devices: Compact Gear Trains for Maximum Torque

Excavator planetary devices—also known as planetary drives or sun-and-planet gearboxes—sit between your hydraulic motor and the swing or travel output shaft, multiplying motor torque into the massive turning or rolling power your machine demands. When gear wear, bearing fatigue, or seal failure occur, you’ll feel sluggish slew or crawl, hear whining under load, or see uneven travel speeds—symptoms that signal it’s time for attention. VI Equipment stocks complete planetary-device assemblies—sun gear, planet gears, carrier, ring gear, bearings, and seals—engineered for drop-in replacement and factory-spec torque output.

Reman & Brand-New Planetary Devices for John Deere, Hitachi & Caterpillar

Whether you need the Bosch-Rexroth planetary on a Hitachi ZX350 swing drive or the Nabtesco travel planetary on a Deere 135G undercarriage, we catalogue planetary devices by machine model, serial prefix, and OEM part number so matching takes minutes. Reman units are cold-stripped, magna-fluxed for cracks, and rebuilt with case-hardened gears, precision-matched bearings, and high-pressure seals—delivering OEM torque at roughly 60 % of dealer cost. Brand-new aftermarket devices use forged 8620 alloy-steel gears, induction-hardened races, and multi-lip Viton seals, all backed by a 12-month unlimited-hour warranty.

Diagnosing Planetary-Device Wear Before It Grounds You

Listen for gear whine under high load, watch for slow travel acceleration, or inspect your travel-motor or swing-drive case-drain for metal slurry—early indicators of internal bypass or gear fatigue. Rising oil temps at idle and erratic speed under steady lever input also point to planetary slip. Pull your magnetic drain-plug sample or record a short video of the noise and email it to our parts desk; we’ll advise whether a seal-kit refresh, partial rebuild, or full planetary swap offers the best ROI.

In-House Planetary-Device Rebuilds: Precision Machining & Dyno Verification

Our Langley gearbox shop completes most planetary-device rebuilds in five business days. We line-bore bearing seats to ± 0.03 mm, lap gears to OEM tooth-profile specs, and fit new tapered-roller bearings shimmed for correct preload. Every assembly is then run on a 200 hp dyno stand, logging torque, backlash, and case temperature at 25 %, 50 %, 75 %, and 100 % load. A printed performance report ships with every unit for full test-traceability.
