Frequently Asked Questions

What filters does Broken Tractor carry for Komatsu WB backhoes?

We carry replacement air, fuel, oil, and fuel/water separator filters for Komatsu WB backhoe loaders. This includes primary and secondary engine air elements, spin-on fuel filters, full-flow lube filters, and fuel/water separators across the WB91, WB93, WB97, WB140, WB142, WB146, WB150, and WB156 series. Match the part number to your machine or contact our parts team to verify fitment.

Which fuel/water separator fits a Komatsu WB93-5?

The fuel/water separator under SKU EA504073234 fits the Komatsu WB93-5, along with the WB97S-5. To confirm the correct filter for your machine, match this part number to your unit or reach out to our knowledgeable team.

What is the difference between primary and secondary air filters for a Komatsu backhoe?

The primary air filter is the outer element that captures most of the incoming dust and debris, while the secondary or inner element provides an added layer of protection for the engine intake. We carry both for Komatsu WB series backhoes, such as primary SKU 2260211111 and secondary SKU 2260211121, which fit models including the WB93, WB97, WB140, and WB146. Replacing both during service helps keep the intake clean.

Which engine oil filter fits a Komatsu WB142-5 and WB146-5?

The engine oil filter under SKU CULF3553 fits the Komatsu WB142-5, WB146-5, WB146PS-5, WB156-5, and WB156PS-5. Confirm your model against this fitment list before ordering, since coverage varies by serial number and configuration.

What spin-on fuel filter fits a Komatsu WB97R backhoe?

The spin-on fuel filter under SKU 11900055600 fits the Komatsu WB97R, along with the WB140-2 and WB150-2. Fitment can depend on model and serial number, so match the part number to your machine or call our parts team at (800) 909-7060 to verify.
