Frequently Asked Questions

How do I know if I need a 5-roller or 6-roller track adjuster for my Case 850?

The correct adjuster depends on your undercarriage configuration, since we carry components sized for both 5-roller and 6-roller setups. For example, the Track Adjuster Rod SKU R31983 fits 5-roller 850B, 850C, 850D, 855C, and 855D machines, while the Yoke Fork SKU D36360 is for 6-roller undercarriages. Match your roller count and part number, or confirm with our parts team before ordering.

What track adjuster parts fit a Case 850H dozer?

For the 850H we carry the Track Adjuster Extension Tube SKU 345071A1, which fits 850D Long Track, 850E, 850G, and 850H in 6-roller configuration, as well as the Track Rod Extension Tube SKU 345070A2. The Idler Spacer Plate SKU R45568 also covers the 850H. Confirm the part number against your machine to ensure correct fitment.

Do you sell a track adjuster seal kit for the Case 850?

Yes, Broken Tractor carries the Track Adjuster Seal Kit SKU 907003, which fits Case 850 dozers. It is intended to reseal the adjuster assembly rather than replace the full unit. Match the part number to your machine to confirm fitment.

Can I replace just the adjuster rod instead of the whole tension assembly on a Case 850?

Yes, we offer individual components so you can replace only what is worn. For example, we carry the Track Adjuster Rod SKU D36361 (11 inches long) and the Track Adjuster Tube SKU D36357 separately, as well as the complete Track Tension Adjuster Assembly SKU D39930 if you need the full unit. Choosing the right option depends on which parts are worn on your machine.

What recoil assembly fits a Case 850K or 850L dozer?

The Recoil Assembly SKU 419386A1 fits Case 850K, 850L, and the 850M LT, WT, and LGP variants, among other models. For the 850K and 850L rod extension tube, we also carry SKU 436240A1, which fits 850K Ser. 2, 850K Ser. 3, and 850L. Confirm your model and serial series when ordering to be sure of the correct part.
