Frequently Asked Questions
What steering clutch discs fit a Komatsu D31 dozer?
Broken Tractor carries a steel steering clutch disc, part number 110-22-11320, and a fiber steering clutch disc, part number 110-22-11332, for the Komatsu D31 series. Both fit the D30S-12, D31A-16, D31P-16, D31Q-16 and D31S-16 dozers. Match the part number on your old disc to choose the correct one.
What is the difference between steel and fiber steering clutch discs on a Komatsu D31?
They are two separate disc types with their own part numbers. The steel disc is 110-22-11320 and the fiber friction disc is 110-22-11332. Both fit the same D30S-12, D31A-16, D31P-16, D31Q-16 and D31S-16 models. Check the disc you are replacing and order by its part number so you get the right type.
What steering clutch drum fits a Komatsu D85E dozer?
Steering clutch drum 15B-22-11130 fits the Komatsu D85E, along with the D75A, D83E and D83P dozers. Broken Tractor offers this drum for that heavier class of Komatsu crawler dozers. Compare the part number on your existing drum to confirm the match before ordering.
What do steering clutch discs and drums do on a Komatsu dozer?
Steering clutch discs and drums manage power transfer to each track, which is how a Komatsu crawler dozer steers. Because they are central to directional control, they wear during normal dozer operation. Replacing worn discs or a worn drum helps restore proper steering control.
How do I make sure a steering clutch part fits my Komatsu dozer?
Start with your exact model, such as D31A-16 or D83E, because fitment can vary by model and serial number. Then match the part number stamped on your old part to the part number listed: 110-22-11320, 110-22-11332 or 15B-22-11130. If you are unsure, call our parts team at (800) 909-7060 to confirm before ordering.
