Frequently Asked Questions

What track adjuster parts do you carry for the John Deere 350 dozer?

Broken Tractor carries a full range of track adjuster and recoil parts for the 350, 350B, 350C, and 350D, including the track tensioner (SKU PV303), track adjuster yoke (SKU T145145), adjuster rod (SKU AT36389), recoil spring assembly (SKU PV601), and seal kit (SKU 905000). We also stock idler plates, shims, and wear plates for these machines. Match the part number to your machine to confirm the correct fit.

Does the 400G Long Track use a different track adjuster than the standard 400G?

Yes, the 400G Long Track uses a dedicated track adjuster assembly (SKU PV302), which is made in USA and listed as fitting the 400G Long Track. Standard 400G machines share many parts with the 350 series, such as the tensioner, yoke, and adjuster rod. If you are unsure which version you have, confirm the part number against your machine before ordering.

What is included in the John Deere dozer track adjuster seal kit?

The track adjuster seal kit (SKU 905000) covers the seals for the adjuster on 350, 350B, 350C, and 350D dozers along with 400G, 440, and 1010 applications. It is intended for the track adjuster and recoil system when you are servicing leaks or rebuilding the assembly. Check the fitment list against your model to be sure it matches your setup.

Which recoil spring fits a John Deere 1010 crawler dozer?

The Track Recoil Spring Assembly (SKU PV601) fits the 1010 along with the 350, 350B, 350C, 350D, and 400G. It is a heavier spring and is made in USA. The matching cover plate (SKU T10018) is also available for the same models.

What is the difference between the threaded idler plate and the guide idler plate for the JD 350?

The Threaded Track Idler Plate (SKU T20851) and the Track Idler Guide Plate (SKU T27516) are separate components used together in the front idler alignment on the 350, 350C, and 350D. Broken Tractor also offers track shims (SKU T20850 and SKU T20852) at 0.0359 inch to set proper alignment. If you need help confirming which plates and shims your machine uses, call the parts team at (800) 909-7060.
