Compatibility Verification

Before purchasing a 109-1589-006 replacement hydraulic motor, it is recommended to verify:

• Complete original motor part number

• Original motor nameplate

• Complete model code

• Equipment brand

• Equipment model

• Equipment serial number

• Displacement

• Mounting flange

• Pilot diameter

• Bolt pattern

• Shaft type

• Shaft dimensions

• Hydraulic port configuration

• Case drain configuration

• Rotation requirements

• Working pressure

• Required flow rate

• Required output torque

• Hydraulic circuit configuration

If the customer can provide the original motor nameplate, complete model code, equipment model, part number, or product photos, further replacement compatibility can be verified.

Compatibility Note: Actual replacement suitability depends on the complete motor configuration, hydraulic pressure, flow rate, mounting dimensions, shaft specifications, port configuration, and equipment hydraulic circuit. Direct interchangeability should not be determined solely by the “109-1589-006” part number or the 4000 Series designation.
