3. Close the shut-off valve for the charge pump suction
line at the oil tank (Figure 11). Disconnect the suction
line at the charge pump and hold the line in a container.
Then open the shut-off valve to drain the oil tank.
4. If equipped, open the bleed valve at or near the high-
est point in the system (Figure 12) to vent the system so
it will completely drain.
NOTE Before refilling the system with clean approved
oil, clean the suction screen in the oil tank, clean
the orifice filters, and replace the converter oil
filters.
5. Close the drain valve at each turbine housing and at
each heat exchanger.
6. Reconnect the charge pump suction line to the
charge pump.
7. Disconnect one of the cooling hoses from the top of
each converter (Figure 13) and fill each converter hous-
ing through the hose. When oil appears at the bleed
valve or when the housings are full, securely reconnect
the hose to each converter.
8. Fill the oil tank to the HIGH mark on the dipstick.
9. Open all shut-oil valves at the oil tank. Then start the
engine and let it run at low speed. Add oil to the tank as
needed to completely fill the system.
10. As the system is being filled with the engine running,
slowly open the bleed valve (Figure 12) to release any
trapped air. Then close the bleed valve.
11. Check the system for leaks and ;)roper charge pres-
sure (45~-65 psi).
