Frequently Asked Questions

How do I know which fuel injection lines fit my Case 580L backhoe?

It depends on which injection pump your 580L has, because the lines are pump-specific. Broken Tractor lists the 580L under both the Lucas/CAV pump lines (J903522 through J903525) and the inline Bosch pump lines (J932157 through J932160). Check your pump type and match the old part number, or call (800) 909-7060 and our parts team can help confirm fitment by model and serial number.

Which injector lines fit a Case 580 Super K or 590 Super L with a 3-bolt Bosch rotary pump?

For Cummins 4-390 engines with the 3-bolt Bosch rotary pump, we carry individual lines J903480, J903481, J903482 and J903483 for cylinders #1 through #4, plus the complete set J903480-3K. These are listed for the Case 580SK, 580SL, 590T and 590SL backhoes. Some of these models were also built with other pumps, so confirm your pump type before ordering.

Are Case backhoe injector lines sold individually or as a set?

Both options are available. Individual lines are sold by cylinder position, #1 through #4, and each position has its own part number, so order the line that matches the cylinder you are replacing. Complete 4-line sets are offered for each pump type: J903522K for Lucas/CAV, J903480-3K for the 3-bolt Bosch rotary, and J932157K for the inline Bosch pump.

What fuel return line fits a Case 580 Super M backhoe?

The fuel return line J927633 is made for Case Cummins 4B engines with the inline Bosch pump and is listed for the 580L, 580 Super L, 580M, 580 Super M, 580MXT, 590 Super L, 590 Super M and 570LXT. For earlier machines, return line J909695 is listed for the 480E, 480F, 580E, 580 Super E, 580K, 580 Super K, 590, 590 Super L and 570LXT. Models that show up under both lines may have different setups, so match the part number on your old line.

Which injection lines fit a Case 580E or 480E backhoe with a Lucas/CAV pump?

For Cummins 4B-390 engines with the Lucas/CAV rotary pump, Broken Tractor offers lines J903522, J903523, J903524 and J903525 for cylinders #1 through #4, or the complete set J903522K. These are listed for the Case 480E, 480E LL, 480F, 480F LL, 580E, 580 Super E, 580K, 580 Super K, 580L and 570LXT. Verify that your machine has the Lucas/CAV pump before ordering, since some of these models also used other pump types.
