PUMP START-UP PROCEDURE
NOTICE
When installing a new pump, you MUST prime (fill) the new pump with hydraulic fluid BEFORE operating, otherwise
damage WILL occur.
When replacing or re-installing the hydraulic pump after repairs, the housing of the pump must be filled with hydraulic fluid
through the case drain port, either before or after mounting the transmission.
1. Attach case drain hose between the pump connection and the reservoir.
2. Connect the inlet hose to the rear of the pump and reservoir. After filling reservoir, loosen top adapter screws on the
inlet and rotate hose adapter down, cracking the top of the adapter away from the pump.
3. Open the tank shut-off valve to purge as much air as possible out of the hose, filling the inlet hose with oil.
4. Tighten the inlet retainer screws, top off fluid level of the reservoir if necessary.
