Remanufactured drivetrain
Remanufactured Komatsu HD785 Differential
Differential failed on the HD785. The truck's sitting. You need a reman diff that fits the serial range, works under load, and ships faster than OEM can get it to you.
We source certified remanufactured Komatsu HD785 differentials through our network of trusted rebuilders. Tell us the truck serial and which axle. We'll confirm the right part number, find the diff, and come back with the price, lead time, and warranty.
No obligation. Asking costs nothing.
What We Need From You
- •Truck model (HD785-5, -7, etc.) and serial number
- •Failed differential part number (if you have it)
- •Which axle (front or rear)
- •Your location (freight matters)
- •When you need it on site
