Nachi Final Drives, Hydraulic Travel Motors, & Wheel Motor Identification

Because Nachi hydraulic motors can be used in different types of mobile equipment, the complete component number should be captured before the old unit is removed. The machine model alone may not be enough to distinguish hydraulic ports, shaft details or reduction configurations.

If the motor has become weak or slow, verify the hydraulic supply and check for external leakage before condemning the unit. When replacement is necessary, send us the Nachi tag and application so we can help compare the correct drive.
