Do you have transmission parts for older Case dozers like the 310?

Our main listed coverage runs across the 450, 550, 650, 750, 850, and 1150 series Case dozers. For an older model such as the 310, the best approach is to match by part number or confirm the correct component with our parts team so you get the right fit for your machine.

Should I replace or repair a Case dozer transmission?

Broken Tractor offers both individual components like gears, clutch packs, and charge pumps for repairs, and complete transmission assemblies when a full replacement makes more sense. If you can isolate the worn part, replacing that component is often the more economical route. For fitment help on either path, call our team at (800) 909-7060.

Do you sell used Case dozer transmission assemblies?
