Frequently Asked Questions

How do I find the right final drive kit for a Case 1150 dozer by serial number?

The original Case 1150 has a serial number break at 2663630, so check your serial number before ordering. Broken Tractor offers the PV709 final drive bearing, gasket and seal kit for 1150 dozers before serial number 2663630 and the PV710 kit for 1150 dozers after that break. For the later 1150B, 1150C, 1150D, 1150E, 1150G, 1150H and 1450 dozers, we carry the G101538-KIT final drive bearing and seal kit.

What final drive pinion shaft fits a Case 1150 or 1450 dozer?

The correct pinion shaft depends on your model and serial number. Early Case 1150 dozers before serial number 2663630 use the A50318 pinion shaft with 12 teeth and 19 splines. The 1150B, 1150C, 1150D, 1150E, 1150G, 1150H and 1450 use the G109013 pinion shaft with 13 teeth and 46 splines, and the 1450B uses the G107943 pinion shaft. Match your old part number or call (800) 909-7060 to confirm before ordering.

Does the Case 1150 final drive bull gear also fit the 1450 dozer?

Yes, the G100294 final drive bull gear fits both the Case 1450 and the 1150B, 1150C, 1150D, 1150E, 1150G and 1150H dozers. For the 1450, Broken Tractor also carries the G100098 46 spline final drive sprocket shaft. Confirm your exact model before ordering, since the 1450B uses different final drive components.

What planetary final drive parts are available for the Case 1450B dozer?

Broken Tractor carries the A168166 planetary gear and the A179586 planetary ring gear for the Case 1450B dozer. We also offer the G107943 final drive pinion shaft and the PV412 weld-on final drive seal spacer for the 1450B. These planetary parts are listed for the 1450B only, not the earlier 1450.

Will the final drive bearing cup fit a Case 850 dozer?

The 160301R1 final drive bearing cup fits the Case 850C, 850D and 850E dozers, and the 850G in the LGP version only. It also fits the 1150B, 1150C, 1150D, 1150E, 1150G, 1150H and 1450 dozers. If you have a standard 850G, match your existing part number before ordering, since the listed 850G fitment is LGP only.
