Gearbox Lubrication
1. Remove the oil fill drain plug on the gearbox (Figure 15). If
the oil level is
correct
oil will begin to leak out. Retighten
drain plug.
2. If the level of the oil in the gearbox is
low
, no oil will leak out
when the drain plug is removed. Add gearbox oil, type SAE
90 through this drain opening. Fill until oil begins to leak out
from the drain opening cavity. If gearbox oil is
low
no oil will
leak out when drain plug is removed. Retighten drain plug.
Vibratory and Travel V-Belt Tension
Check the tension of the vibratory and travel V-belts
(Figure 16). This tension can be checked by the amount
of deflection when the belt is pressed midway between
the two pulleys. The deflection of the travel belt should
be approximately 3/4 of an inch (2 cm.), the vibratory V-
belt should have a deflection of approximately 2 to 2-1/2
inches (5 to 6 cm.)
Clogged Drive Belt Tension
Check the tension of the clogged V-belt (hydrostatic pump). This
tension can be checked by the amount of deflection when
the belt is pressed midway between the two pulleys. The
deflection of the travel belt should be approximately 1/2
of an inch (1.27 cm.).
