Frequently Asked Questions
What rock guards fit a Cat D5K2 with SystemOne undercarriage?
Broken Tractor carries left hand and right hand track rock guards for the Caterpillar D5K and D5K2 with SystemOne undercarriage. The right hand rock guard is part number 356-5278 and the left hand rock guard is part number 356-5282. Match the part number on your old guard before ordering to confirm the fit.
Are Cat D5K rock guards sold as a pair or individually?
Left hand and right hand rock guards for the Cat D5K and D5K2 are sold individually as separate parts. This lets you replace only the side that is damaged or worn. Verify which side you need before ordering, since the left hand (356-5282) and right hand (356-5278) guards are different part numbers.
Do Cat D5K rock guards fit a dozer without SystemOne undercarriage?
The rock guards we carry for the Cat D5K and D5K2 are designed specifically for machines equipped with SystemOne undercarriage. If you are not sure which undercarriage system your dozer has, compare the part number on your existing guard or confirm with our parts team at (800) 909-7060 before ordering.
What does a track rock guard do on a Cat dozer?
A track rock guard shields the track rollers and lower undercarriage from rock impact and abrasive material. On a Cat D5K or D5K2 with SystemOne undercarriage, a guard in good condition helps extend the service life of undercarriage components. A bent, cracked or missing guard leaves the rollers exposed to rock and debris damage.
