Excavator Swing Gear Boxes: Precision Planetaries for Perfect Slew

Swing gear boxes (slew planetaries) sit between the swing motor and the slew bearing, multiplying motor speed into the massive torque that rotates the upper structure smoothly and stops it exactly where the operator wants. Spalled gear teeth, worn bearings, or cracked housings translate into jerky starts, excessive backlash, and noisy operation. VI Equipment carries complete swing gear boxes—sun, planet, ring gears, carrier, bearings, and seals—engineered to bolt straight in and restore factory slew precision.

Reman & Brand-New Swing Gear Boxes for John Deere, Hitachi & Caterpillar

Whether you’re running a Deere 160G LC with a KYB planetary or a Cat 330 GC with a Bonfiglioli unit, we stock gear boxes matched by machine model, serial range, and OEM part number. Reman gear boxes are stripped, crack-checked, and rebuilt with new bearings, shims, and lapped gears—delivering OEM torque at ≈ 60 % of dealer pricing. Want brand-new? Our premium aftermarket line uses forged 42CrMo gears, induction-hardened races, and high-temp Viton seals, all warrantied for 12 months.

Early Warning Signs of Swing Gear-Box Failure

Listen for a rising howl during rotation, check for oil weeping past the turret seal, and measure backlash at the bucket tip—more than 30 mm of play usually traces back to gearbox wear. Monitor case-drain flow from the swing motor; excess flow points to bypass that overloads the planetary. Send us a short phone video of the slewing lag or a photo of plug debris and we’ll advise whether a reseal kit, bench rebuild, or complete swap is your most cost-effective path.

In-House Swing Gear-Box Rebuilds: Lapped, Pre-Shimmed & Torque-Tested

Our Langley gearbox shop finishes most swing gear-box rebuilds in five business days. Gears are lapped to a surface finish <0.4 µm Ra, carriers crack-checked, and tapered bearings shimmed to OEM preload. Each unit is spun on a 250 hp slew-test stand where breakout torque, backlash, and case temperature are logged at stepped loads. A printed test report ships with every gearbox so you have full traceability.

Core Exchange Program: Fast Turnaround, Lower Costs

Send in your worn planetary and leave with a dyno-tested reman the same day. Core credit posts after inspection—dropping net cost and diverting thousands of kilos of cast iron from the scrap yard. Ask our parts desk for today’s core values and prepaid freight.
