Excavator Swing Motors: Hydrostatic Power for Smooth Slew

Swing motors (also called slew motors) convert hydraulic flow into the rotational torque that spins your excavator’s upper structure. When bearings wear, internal gears gall, or seal packs leak, you’ll feel sluggish starts, uneven slew speeds, or overheating—symptoms that signal the motor’s time is up. VI Equipment stocks complete excavator swing motors—housing, rotors, shafts, bearings, and seals—that bolt straight in and restore factory torque and flow.

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

Whether it’s a KYB unit on a Deere 160G LC, a Bosch-Rexroth motor on a Hitachi ZX300, or a Kawasaki drive on a Cat 336, we catalogue swing motors by model, serial prefix, and OEM part number so matching takes minutes. Reman motors are stripped to bare casing, magna-fluxed for cracks, and rebuilt with new rotor assemblies, tapered-roller bearings, and multi-lip seals—delivering factory specs at roughly 60 % of dealer cost. Brand-new aftermarket motors feature heat-treated shafts, nitrile seals rated to –40 °C, and come with a 12-month unlimited-hour warranty.

Diagnosing Swing Motor Wear Before It Grounds You

Listen for grinding or whine during rotation, feel for excessive shaft play, or inspect case-drain oil for milky emulsions—classic signs of internal seal failure or gear fatigue. Rising hydraulic oil temps at idle and erratic slew speed under steady lever input also point to motor bypass. 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, partial rebuild, or full motor swap offers the best ROI.

In-House Swing Motor Rebuilds: Precision Balancing & Dyno Testing

Our Langley hydraulic lab completes most swing-motor rebuilds in five business days. We strip and clean every component, replace bearings and seals, and balance rotors to ISO 1940 Grade G2.5. Each motor is then run on a 250 hp slew stand where we log torque output, case-drain flow, and temperature rise at 25 %, 50 %, 75 %, and 100 % load. A printed performance report ships with every motor so you know it meets spec before it goes back on your machine.
