PROBLEM

Show/hide table

The existing 373-6631 Hydraulic Fan Pump may wear prematurely and fail on certain D10T Large Track-Type Tractors. If the existing hydraulic fan pump fails, it can/will fail the rotary group internal to the pump, generate debris, contaminate the fan system, and cause extensive damage to other components. It is better to replace the fan pump at the very earliest convenience prior to a potential major failure.
