Frequently Asked Questions
Which Cat D6 dozer transmission fits my machine?
Broken Tractor offers a rebuilt transmission assembly, SKU 9W1720, for the Cat D6H and D6H LGP. For later D6 machines, we carry final drive SKU 2606650, which fits the D6R, D6R2 and D6T in several configurations. Match your exact model and configuration before ordering, since D6 drivetrain parts differ between generations.
Does the Cat D6T final drive also fit a D6R?
Yes, final drive SKU 2606650 fits both the D6R and the D6T, as long as the serial number falls in the listed ranges. Listed D6R fitment covers D6R STD, XL and LGP serials S6T00001-UP and S6X00001-UP, plus D6R2 STD, XL and LGP serials SSS00001-UP and TTT00001-UP. On the D6T it fits XL, XW, LGP and STD machines from specific serial prefixes such as LAE00001-UP, JHB00001-UP and PEZ00001-UP.
Is a rebuilt Cat D6H dozer transmission a good alternative to new?
Our rebuilt Cat D6H and D6H LGP transmission assembly, SKU 9W1720, is tested and assembled to meet OEM specifications. That makes it a practical way to get a D6H back to work with a complete assembly instead of rebuilding the original transmission yourself.
Do you carry parts for a Cat D3 dozer?
Yes, Broken Tractor carries joystick handle SKU 113-2531, which fits the Cat D3C III dozer. The same handle also fits the D4C III and D5C III dozers. Check that your machine is a Series III model before ordering.
What should I check before ordering a Cat dozer transmission or final drive?
Confirm your exact model, configuration (STD, LGP, XL or XW) and serial number prefix, because fitment on D6R and D6T final drives is tied to serial ranges. Matching the part number from your old component is the most reliable way to get the right fit. If you are unsure, call (800) 909-7060 and our parts team can confirm fitment.
