Frequently Asked Questions

What engines do these Case trencher timing covers fit?

These timing covers fit Cummins 4B and 6B blocks built around the 4-bolt injection pump configuration. They serve as the front engine cover that seals the timing gear train. Confirm your engine uses the 4-bolt pump mounting before ordering.

Which Case trencher models does the timing cover fit?

Our covers cover a wide range of Case machines running Cummins 4B/6B power, including the 570LXT and 570MXT trenchers. Because fitment spans many models and configurations, match the part number to your unit or confirm with our parts team to be sure you get the correct cover.

Do you carry new and used Case trencher timing covers?

Yes, Broken Tractor offers both new replacement timing covers and inspected used units. The used covers are checked before shipping. Verify the gasket and seal surfaces on any cover before install.

What is the difference between SKU J936257 and J920758U?

SKU J936257 is a new timing cover for Cummins 4B/6B with the 4-bolt pump, while SKU J920758U is an inspected used Cummins timing cover. Both are designed for the 4-bolt injection pump configuration but fit slightly different model ranges. If you are unsure which one matches your machine, call our parts team at (800) 909-7060.

Do I need a new gasket when replacing a Case trencher timing cover?

You should always inspect the gasket and seal surfaces before installing a timing cover. Reusing worn seals can lead to oil leaks at the timing gear train. Confirm the sealing surfaces are clean and true for a proper seal.
