Why Shop VI Equipment for Your Excavator Swing Drives

There are many reasons to choose VI Equipment for your excavator swing drives. We offer exceptional value, unmatched selection, and reliable performance to keep your projects on track. Discover the VI Equipment difference and experience the benefits firsthand.

Excavator Swing Drives: Smooth Rotation and Precision Placement

The swing drive (or slew gearbox) translates hydraulic motor power into the controlled 360° rotation that lets your excavator place every bucket exactly where you want it. When gear teeth spall or bearings pit, you’ll feel jerky starts, uneven slew speeds, or a howl that drowns out the engine—early signs the heart of your upper frame needs attention. VI Equipment stocks fully dressed swing drives and planetary gearboxes that bolt straight in, restore factory slew torque, and stop that costly swing drift before it turns into downtime.

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

From a Deere 135G’s KYB gearbox to a Cat 336’s Rexroth planetary, we catalogue swing drives by machine model, serial prefix, and OEM reference so matching takes minutes, not hours. Reman units are stripped to bare casting, crack-checked, and rebuilt with new bearings, shims, and lapped gear sets—delivering OEM torque at roughly 60 % of dealer cost. Prefer brand-new? Our premium aftermarket line uses forged 42CrMo gears, case-hardened races, and viton seal packs, all backed by a 12-month unlimited-hour warranty.

Diagnosing Swing Drive Wear Before Productivity Drops

Watch for sluggish slew acceleration, oil leaking from the turret seal, or metal flakes in the gearbox plug—classic indicators of bearing and gear wear. Track motor case-drain flow; anything over 10 % of rated displacement suggests internal bypass and impending gearbox overload. Send us a quick phone video of the slew lag or a sample of your magnetic plug debris and we’ll confirm whether a reseal kit, bench rebuild, or full replacement offers the best ROI.

In-House Swing Drive Rebuilds: Shimmed, Lapped & Dyno-Spun

Our Langley gearbox lab turns most swing-drive rebuilds in five business days. We cold-strip housings, magna-flux gears for cracks, and lap sun, planet, and ring gears to a mirror finish that cuts noise up to 5 dB. Taper bearings are preload-shimmed to OEM spec, and every rebuilt unit runs on a 250 hp slew-test stand where we log breakout torque, back-lash, and case-temperature rise at 25 %, 50 %, 75 %, and 100 % load. A printed torque curve ships in the crate so you know exactly what’s going back into your machine.
