Frequently Asked Questions

What starter fits a John Deere wheel loader?

Broken Tractor carries 12V and 24V starters in Delco, Denso, and Bosch styles that fit John Deere wheel loaders from the 344E through the 844K. Part numbers include RE41755, RE549229, RE515895, TY6712, TY6787, and TY25961. The correct starter depends on your loader's model, serial number, and system voltage, so match the part number on your old starter or confirm with the parts team at (800) 909-7060.

What alternators are available for John Deere wheel loaders?

We carry 12V and 24V alternators in Bosch and Motorola styles, with outputs from 55A through 130A, for John Deere wheel loaders. Part numbers include AT103344, AT161324, AT208541, AT300167, RE558676, SE501362, and TY6799. Match the voltage, amperage, and part number of your current alternator, because fitment varies by model and serial number.

What replaces the AT560845 backup camera on a John Deere loader?

The Orlaco 4-pin cab camera, part number AT466877, replaces AT560845, AT437274, and CAM845. It fits John Deere wheel loaders from the 444K through the 944K. Check your old camera's part number to confirm it matches one of those replaced numbers.

What alternator belt fits a John Deere 844K loader?

Alternator belt R531353 fits the John Deere 844K, and it also fits the 824K, 844K-III, 844L, and 844LAH wheel loaders. Compare it against the part number on your current belt before ordering.

What sensors does Broken Tractor carry for John Deere wheel loaders?

We offer engine, fuel system, and emissions sensors for John Deere wheel loaders. These include magnetic pickup sensors (RE537634, RE519144), manifold air pressure sensors (RE537639, RE522723), a fuel rail pressure sensor (RE536275), an oil pressure sensor (RE167207), and water in fuel sensors (RE539872, DZ117493, DZ110639). We also carry a NOx sensor (RE553441), an EGR temperature sensor (RE537636), and a diesel oxidation catalyst pressure sensor (RE538131). Match the part number on your existing sensor, since fitment varies by model and engine.
