Checking the Torque of the
Wheel Nuts
F ailur e to maintain pr oper torque of the wheel
n uts could r esult in f ailur e or loss of wheel and
may r esult in per sonal injur y .
T orque the fr ont and r ear wheel n uts to
85-100 ft.-lb . (115-136 N·m) after 1-4 hour s of
operation and a gain after 8 hour s of operation.
T orque ev er y 200 hour s ther eafter .
Note: F ront wheel n uts are 1/2-20 UNF . R ear wheel
n uts are M12 x 1.6-6H (Metric).
Checking the Planetary Gear
Drive Oil
Chec k the oil lev el after ev er y 400 hours of operation
or if exter nal leakag e is noted. Use high quality SAE
85W -140 wt. g ear lube as a re placement.
T he capacity of the system is appro ximately 16 oz.
(0.5 l).
1. With the mac hine on a lev el surface , position the
wheel so that the c hec k/drain plug ( Figure 41 ) is
at either the 2 or 10 o’cloc k position.

1. Check/drain plug
2. R emo v e the plug on the planetar y ( Figure 41 ). Oil
should be at the bottom of the c hec k plug hole .
3. Add g ear oil to the hole in the planetar y , if
necessar y , to bring the oil up to the proper lev el.
Install the plug .
4. R e peat ste ps 1 – 3 on the opposite g ear assembly .
Changing the Planetary
Gear Drive Oil
Chang e the oil initially after first 200 hours of
operation. T hereafter c hang e the oil ev er y 800 hours ,
or yearly , whic hev er occurs first. Use a high quality
SAE 85W -140 wt. g ear lube .
1. With the mac hine on a lev el surface , position the
wheel so that the c hec k/drain plug ( Figure 42 ) is
at the lo w est position (6 o’cloc k).
