Drive System
Maintenance
Checking the Torque of the
Wheel Nuts or Bolts
Service Interval: After the first 8 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel nuts
could result in personal injury.
Torque the front wheel nuts and rear wheel bolts to
85-100 ft.-lb. after 1-4 hours of operation and again
after 10 hours of operation. Torque every 200 hours
thereafter.
Checking the Planetary Gear
Drive Oil
Service Interval: Every 400 hours (Also, check if
external leakage is observed)
Check the oil level every 400 hours of operation.
Use high quality SAE 85W-140 wt. gear lube as a
replacement.
1. With machine on level surface, position the wheel
so one check plug (Figure 63) is at the 12 o'clock
position and the other is at 3 o'clock position.

1. Check plug (2)
2. Remove the plug at the 3 o'clock position (Figure 63).
Oil level should be at the bottom of the check plug
hole.
3. If the oil level is low, remove the plug at the 12
o'clock position and add oil until it begins to flow
out of the hole at the 3 o'clock position.
4. Re-install both plugs.
5. Repeat steps 1 through 4 on the opposite planetary
gear assembly.

Changing the Planetary Gear
Drive Oil
Service Interval: After the first 200 hours
Every 800 hours (Or yearly, whichever
comes first)
Change the oil initially after 200 hours operation.
Thereafter, change the oil every 800 hours. Use high
quality SAE 85W-140 wt. gear lube as replacement.
1. With machine on level surface, position a wheel
so one of the check/drain plugs is at the lowest (6
o'clock) position (Figure 64).

1. Check/drain plug
2. Place a drain pan under the planetary hub, remove
plug and allow oil to drain.
3. Place a drain pan under the brake housing, remove
the drain plug and allow the oil to drain (Figure 65).

4. When all of the oil has drained from both locations,
re-install the plug in the brake housing.
5. Rotate the wheel until the open plug hole in the
planetary is at the twelve o'clock position.
6. Through the open hole, slowly fill the planetary with
22 ounces. (0.6 liter) of high quality SAE 85W-140
wt. gear lube.
