We'd rather tell you this upfront than have you order the wrong part: Eaton is not typically the OEM brand behind a bulldozer's main blade-lift pump — that role usually belongs to Komatsu, Caterpillar, or Bosch Rexroth. Where Eaton genuinely earns its place on a bulldozer is the JMV series track drive motor, used across construction equipment from 1.5 to 50 tonnes, and in Eaton's heavy-duty closed-circuit piston pumps found in some hydrostatic drive systems on construction and agricultural machinery.
What We Actually Supply for Bulldozers
If your bulldozer's blade is weak rather than the track drive, the fault almost certainly lies with the main OEM pump (Komatsu, CAT or Rexroth), not an Eaton component. See our Komatsu Bulldozer Pump or Rexroth Bulldozer Pump pages for that.
What Our JMV Refurbishment Covers
Measured against Eaton tolerance; replaced where wear exceeds spec.
Gear teeth and bearings inspected — the JMV's reduction gear is what delivers final torque to the sprocket.
Tested to confirm correct slope-holding and overpressure protection behaviour.
Wet friction plates and spring-apply mechanism inspected and rebuilt as needed.
The high-torque/high-speed shift mechanism is tested to confirm it switches correctly under load.
Why Fleet Managers Choose Refurbished Eaton Drive Components
A Genuine Aftermarket Alternative
When your bulldozer's OEM track drive motor is expensive or slow to source, a refurbished Eaton JMV — engineered specifically to fit common installation patterns — is a proven substitute.
Fleet-Friendly Economics
Track drive motors are among the more expensive undercarriage components on a bulldozer. Refurbishment typically saves 40-60% against new OEM pricing.
Honest Diagnosis First
We'd rather confirm your actual fault over WhatsApp than sell you an Eaton component that isn't the real cause of your machine's symptom.
3-Month Warranty on Every Unit
Confirmed in writing, with replacement rather than repair for any refurbishment defect within the warranty period.
Signs Your Track Drive Motor Needs Attention
If the blade itself is weak rather than track drive, WhatsApp us — you likely need the main OEM pump, not an Eaton component.
