7. Planetary Hubs and Wheel Bearings
Lube Type - SSGL-5
Lube Interval - Check fluid level every 500 hours or 3
months and refill as necessary. Drain and refill every
4000 hours or 2 years.
CAUTION
Use of non-extended service interval lubricant may
damage components and/or invalidate published lubricant
intervals.
Lube Amount - 5.2 liters (10.9 pints)
Application - Fill to the bottom of the level hole in the
housing with the fill plug and the oil level mark
horizontal.
NOTE: Refer to illustration
"Differentials" for proper checking of lube levels.
8. Engine Crankcase (Cummins QSB-275)
Lube Type - EO-15W40
Lube Interval - Check fluid level every 10 hours or daily;
drain, fill and replace filter every 500 hours
Lube Amount - Capacity - 16.1 liters (17 quarts)
Application - Fill to full mark on dipstick.
9. Transmission, Torque Converter and Filter
Lube Type - HYDO
Lube Interval - Check fluid level every 10 hours or daily
with the engine running at 1000 rpm idle and the oil at 82
to 93 °C (180 to 200°F); Drain and refill every 1000
hours or 6 months with the oil at 65 to 93 °C (150 to 200
°F). Change transmission filter after the first 50 and 100
hours of service, then every 500 hours thereafter.
NOTE: Transmission filters are located on the outside left
hand frame in the area of the hydraulic oil cooler.
To add fluid:
a. Fill to FULL mark on dipstick.
b. Run engine at 1000 rpm to prime torque converter
and lines.
c. Check oil level with engine running at 1000 rpm and
oil at 82 to 93 °C (180 to 200 °F). Add oil to bring oil
level to FULL mark on dipstick
NOTE: When checking the oil level, the oil temperature
must be stabilized at 82 to 93 °C (180 to 200 °F) to
properly check the oil level. Do not attempt an oil
l e v e l c h e c k w i t h c o l d o i l . To b r i n g t h e o i l
temperature to this range, it is necessary to either
work the crane or stall the converter. Converter stall
and instructions under
should be accomplished by engaging the 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.
CAUTION
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.,
1 2 0 ° C ( 2 5 0 ° F ) m a x i m u m , w i l l c a u s e d a m a g e t o
transmission clutches, fluid, converter, and seals.
NOTE: Do not operate the machine in two wheel drive
while the machine is up on outriggers. Serious
transmission damage may result.
