Frequently Asked Questions
What fuel cap fits a Komatsu HM400 articulated dump truck?
Broken Tractor offers fuel cap SKU 423-04-11362, which is listed for the Komatsu HM400 series in both ecot3 and W/O EGR configurations. Matching the part number on your current cap is the easiest way to confirm you are ordering the right replacement.
Does the same fuel cap fit the Komatsu HM300 and HM350?
Yes, fuel cap SKU 423-04-11362 is listed for the HM300, HM350 and HM400 series Komatsu articulated dump trucks. This makes it a common replacement cap if you run more than one HM model in your fleet.
Will a Komatsu HM400 fuel cap fit both ecot3 and non-EGR engines?
Fuel cap SKU 423-04-11362 is listed for both the HM400 ecot3 and HM400 W/O EGR versions. Because fitment can vary by model and serial number, compare the part number on your old cap or confirm with our parts team before ordering.
Is Komatsu fuel cap 20Y-04-11160 the right cap for an HM series dump truck?
No, fuel cap SKU 20Y-04-11160 is not listed for the Komatsu HM300, HM350 or HM400 articulated dump trucks. For HM series trucks, the listed fit is SKU 423-04-11362. If you are unsure which cap your truck uses, call (800) 909-7060 and our parts team can help match it.
Does an aftermarket fuel cap seal like the original Komatsu cap on HM dump trucks?
The fuel caps we carry for Komatsu HM series dump trucks are made to match original Komatsu fuel cap specifications for proper sealing and fit. If your current cap no longer seals or fits correctly, replacing it with the matching part number restores a proper fit on the fuel tank.
