Good To Know

Q: Is this a new starter or a rebuilt one? A: It is listed as a new starter, not a remanufactured unit, so there is no core charge or core return to manage.

Q: Will this fit my specific Case machine? A: Fitment depends on the engine serial number and machine configuration, so confirm your 3.9L or 5.9L diesel application before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
