Situation:
As a continuous improvement change, the Pump Drive Coupler that transfers engine power to the
traction pump has been redesigned with cast hubs and a more robust coupler. This new design
improves the reliability with a simplified coupler design.
Instructions:
In the event that a previous design (welded steel) coupler requires replacement, the new Pump Drive
Coupler (120-3477) should be installed. This part number represents a kit with 2 cast hubs, the rubber
coupler and the 4 fasteners. Individual parts of the new coupler cannot be intermixed with the older
(welded) coupler design. Should you have any questions, please contact your Toro distributor.
