Frequently Asked Questions

Which track adjuster fits a John Deere 450G dozer?

It depends on the undercarriage configuration and serial number. Track adjuster assembly PV304 fits the 450G and 455G with 5 bottom rollers, while PV314 fits the 450G Long Track and LGP with 6 bottom rollers after serial number 770863. Check your roller count and serial number before ordering, and match the part number to your machine.

What is the serial number break for John Deere 550G track adjusters?

The break falls at serial number 770862/770863. Complete track adjuster PV306 and track adjuster rod AT124171 fit the 550G before serial number 770862. Track adjuster PV314 and rod AT124173 fit the 550G after serial number 770863.

Does Broken Tractor carry a track tension recoil spring for the John Deere 650G?

Yes, we carry track tension recoil spring T105605, which fits the John Deere 650G, 650H, 650J and 650K dozers. For the 450G and 550G, recoil spring T106882 fits along with many other 450 and 550 series models, including the 450C, 450H, 550J and 550K. Rear recoil spring threaded cap T32049 is also offered for 450G, 550G and 650G dozers.

Can I reseal a John Deere dozer track adjuster instead of replacing it?

Broken Tractor offers both options. Track adjuster seal kit 905003 fits a wide range of John Deere dozers, including the 450G, 550G, 650G, 450J and 550K. We also carry complete track adjuster assemblies, track adjuster rods and yokes for the 450G, 550G and 650G if you would rather replace the parts.

Which track spring covers fit a John Deere 650G dozer?

For a 650G after serial number 770863, right-hand cover T158535 and left-hand cover T158536 fit. Rear right-hand cover AT175394 and rear left-hand cover AT175395 fit the 450G LT, 550G and 650G. Spring cover fitment varies by side, serial number and track configuration, so confirm with the parts team at (800) 909-7060 if you are unsure.
