Frequently Asked Questions

What track shoe sizes fit a John Deere 850 dozer?

Broken Tractor offers single grouser track shoes for the John Deere 850, 850B, 850B-LT, 850C and 850C-II-LT in 20 inch, 22 inch and 24 inch widths. A matching track shoe bolt and nut kit (CR2084BK-JD) is also available for these models. Measure your current shoe width or match the part number to choose the right size.

What track shoes fit a John Deere 700J, 700K or 700L dozer?

Track shoe fitment on the 700J, 700K and 700L depends on whether the machine is a standard, LT or LGP configuration. The 20 inch single grouser shoe (CR4392/20-JD) fits standard 700J, 700K and 700L dozers. The 24 inch, 28 inch and 30 inch shoes fit LGP versions, and the 22 inch shoe (CR4392/22) fits the 700J LT, 700J LGP and 700L LGP. Confirm your machine's configuration and match the part number before ordering.

Which front idler fits a John Deere 700K dozer?

We carry two front idler options for the 700K: the standard Front Track Idler Assembly (AT220995), which also fits the 700H and 700J, and the Max Life Track Idler Assembly (AT341193), an extended-wear option that also fits the 700J. The 700L uses a different front idler (AT493538) for LT, XLT and LGP undercarriages. For the 750, 750B, 750C and 750C-II, including LT and LGP versions, the Track Idler Assembly ID1453 is the match.

Do I need a single flange or double flange bottom roller for my John Deere 750 dozer?

It depends on which roller position you are replacing, so order the same flange type as the roller you are removing. Broken Tractor offers both a single flange bottom roller (AT322789) and a double flange bottom roller (AT322790), and both fit the 700H, 700J, 700J-II, 700K, 700L, 750, 750B, 750C, 750C-II, 750J, 750K and 750L. Checking the part number on your existing roller is the easiest way to get the right one.

Which top track roller fits a John Deere 750 or 750C dozer?

The John Deere 750 and 750B use the Press-in Top Track Roller with Seal (AT166779), and the duo seal for that roller (AT78946) is also sold separately. The 750C, 750C-II, 750J, 750K and 750L, along with the 700H through 700L, use the Top Track Roller AT306803. If you are not sure which roller your machine has, match the part number or call (800) 909-7060 to confirm with the parts team.
