• Check level every 10
hours or daily
• Drain and refill every
1000 hours or 6
months
• Change transmission
filter after first 50 and
100 hours of service,
then every 500 hours
thereafter
Through fill pipe to
FULL mark on
dipstick
NOTE:
• Check the transmission fluid level with engine running at 850 rpm idle and the converter oil at 83°C to 93°C (180°F to 200°F). Do
not attempt an oil level check with cold oil. To bring the oil temperature to this range, it is necessary to either work the crane or
stall the converter. Converter stall should be accomplished by engaging shift lever in forward high range with the brakes applied
and then accelerating the engine to half or three-quarter throttle. Hold the stall until the required converter temperature is
reached and stabilized. (Do not operate the converter at stall condition for longer than 30 seconds at one time. Shift to neutral for
15 seconds and repeat the procedure until the desired temperature is reached. Excessive temperature, i.e, 120°C (250°F)
maximum will cause damage to transmission clutches, fluid, converter and seals.)
• Drain the oil at 65°C to 93°C (150°F to 200°F).
• Transmission filters are located on the outside left hand frame in the area of the hydraulic oil cooler inside left hand engine cover.
• To add fluid:
a. Fill to FULL mark on dipstick
b. Run engine at 850 rpm to prime torque converter and lines
c. Check oil level with engine running at 850 rpm and converter oil at 82°C to 93°C (180°F to 200°F). Add oil to bring
oil level to FULL mark on dipstick.1
