NOTES
13. CHANGING TORQUE CONVERTER FLUID. Change the torque converter fluid every three months. Make certain
the winch engine is not operating. Do not drain oil into bilges; use the oil separation and recovery system to collect the
drained oil. To drain converter remove plug in bottom of turbine housing. Remove plug in reserve tank. Drain radiator.
Clean screen element in bottom of reserve tank and remove orifice assembly. Clean filter screen and hole in orifice.
Install orifice assembly and drain plug. Open vent valve on top of the turbine housing and bleed valve on top of the
radiator. Remove radiator filler cap. Add approximately 7 gallons (26.5 liters) of oil (OE/HDO) through the radiator filler
opening until fluid flows from the vent on top of the turbine housing. Close vent valve and continue filling, until the oil
level reaches the filler opening. Then close bleed valve. Tightly install filler cap to prevent leakage when operating.
Remove filler cap from reserve tank. Fill tank with approximately 3 qts (2.84 liters) of oil (OE/H DO), to one inch below
the full mark on dip stick. Install filler cap, start engine and operate at half throttle. Check all fittings for leaks. Check
pressure gage for operating pressure. Normal operating pressure is 45 to 65 PSI, and fluid temperature is under 200
F
when converter is properly filled and vented. The pressure gage responds instantly to full pressure upon starting engine
and zero pressure upon stopping. Sluggishness indicates air trapped within unit requiring further venting at the high point
bleed valve. At part-throttle operation, check reserve tank oil level frequently to ensure adequate fluid level. Add fluid
as required.
14. DRY TYPE AIR CLEANER. Clean air cleaner element with compressed air every two months, and replace annually.
CAUTION
Air pressure at nozzle of air hose must not exceed 100 PSI.
Inspect cleaned element. If thin spots, pin holes or rupture is found, replace element.
