Drive System
Maintenance
Checking the Torque of the
Wheel Nuts
Service Interval: After the first 8 hours
Every 200 hours
Failure to maintain proper torque of the wheel
nuts could result in failure or loss of wheel and
may result in personal injury.
Torque the front and rear wheel nuts to
85-100 ft.-lb. (115-136 N·m) after 1-4 hours of
operation and again after 8 hours of operation.
Torque every 200 hours thereafter.
Note: Front wheel nuts are 1/2-20 UNF. Rear wheel
nuts are M12 x 1.5-6H (Metric).
Checking the Planetary Gear
Drive Oil
Service Interval: Every 400 hours
Check the oil level after every 400 hours of operation
or if external leakage is noted. Use high quality SAE
85W-140 wt. gear lube as a replacement.
The capacity of the system is approximately 16 oz.
(0.5 l).
1. With the machine on a level surface, position the
wheel so that the check/drain plug (Figure 44) is at
either the 2 or 10 o'clock position.
1. Check/drain plug
2. Remove the plug on the planetary (Figure 44). Oil
should be at the bottom of the check plug hole on
the back side of the brake.
3. Add gear oil to the hole in the planetary, if necessary,
to bring the oil up to the proper level. Install the
plug.
4. Repeat steps 1–3 on the opposite gear assembly.
Changing the Planetary Gear
Drive Oil
Service Interval: After the first 200 hours
Every 800 hours
Yearly
Change the oil initially after first 200 hours of operation.
Thereafter change the oil every 800 hours, or yearly,
whichever occurs first. Use a high quality SAE 85W-140
wt. gear lube.
1. With the machine on a level surface, position the
wheel so that the check/drain plug (Figure 45) is at
the lowest position (6 o'clock).
