Frequently Asked Questions
Which engine side shields fit a Cat D3C or D4C dozer?
Broken Tractor carries the right engine side shield panel 135-3086 and the left engine side shield 135-3087 for Cat D3C and D4C dozers. These panels are serial number specific. The 135-3086 lists D3C serial prefixes 6SL, 7XL, 4KS, 4TS, 5GS and 9TS, and D4C serial prefixes 6YL, 7SL, 8CS, 6BS, 4LS and 1FW. Check your machine's serial number before ordering, or call (800) 909-7060 to confirm fitment with the parts team.
Does the PV6010 AC guard fit a Cat D6K with rear sweeps?
No, the PV6010 AC guard fits K and K2 series Cat dozers without rear sweeps only. It is listed for the D3K, D3K2, D4K, D4K2, D5K, D5K2, D6K and D6K2. If your machine has rear sweeps, this guard is not the correct fit.
Are Cat D3G, D4G and D5G engine side shields sold individually or as a set?
For the Cat D3G, D4G and D5G, we carry the engine side shields individually. Part 177-2283 is the right-hand shield and part 177-2284 is the left-hand shield. Order one side or both, depending on which panels need replacing.
What engine side shields fit a Cat D3 or D3B dozer?
Broken Tractor offers a matched left and right engine side shield set, part number 6S9655/6S9650, for the Cat D3 and D3B dozer. The set covers both sides of the engine compartment in one order. Matching the part number on your old panels is the easiest way to confirm you have the right set.
What does an engine side shield do on a Cat dozer?
An engine side shield mounts on the left or right side of the powerplant on a Cat crawler dozer. It protects the engine and drivetrain components from debris and damage. A missing, bent or torn shield leaves those components exposed, so replacing it with the correct left-hand or right-hand panel for your model restores that protection.
