Frequently Asked Questions
Which Komatsu dozers does the 25 tooth drive sprocket fit?
Our 25 tooth track drive sprocket (SKU IN3492) fits the Komatsu TD8C, TD8E, TD8E-LGP, TD8G, TD9H, TD9H-LGP, TD9M, TD10M, TD10M-LGP, D39E-1 and D39P-1 dozers. It is not listed for the TD7 series or the D39PX models, so check your exact model before ordering.
Which bottom track roller fits a Komatsu TD8 dozer?
Broken Tractor carries two single flange bottom track rollers, and the right one depends on your TD8 model. SKU IN2808 fits the TD8C, TD8E, TD8E-LGP and TD8G, along with the TD9H, TD9M, TD10M and D39E-1/D39P-1. SKU IN3490 fits the TD8E, TD8E-LGP, TD8H, TD8H-LGP and TD8M, plus the TD7 series and D32/D38 models. Because both rollers list the TD8E and TD8E-LGP, match the part number on your old roller or confirm your serial number with our parts team at (800) 909-7060.

The same roller also fits the TD8, TD9 and TD10 series and the D32E, D32P, D39E-1 and D39P-1. It covers standard, LGP and wide-track versions where those models are listed.
What track shoes fit a Komatsu D39PX or D41P dozer?
We offer a 24 inch single grouser track shoe (SKU CR4358/24-KOM) for the Komatsu D39PX-21, D39PX-22, D39PX-23, D39PX-24, D39PXi-23, D39PXi-24, D41P-6 and D41P-6K. If you run a different shoe width, compare it with your current shoes before ordering.
