2. Place clean container, large enough to collect 2 gal-
lons (7.6 liters), under the oil filter assembly to collect hy-
draulic oil.
3. Crack open oil filter and allow at least 2 gallons (7.6
liters) of hydraulic oil to drain into the container, then
tighten oil filter to stop drainage. Uncap hydraulic oil tank
and allow enough time for the hydraulic oil to drain out
of the leak detection tank into the hydraulic oil tank.

yellow/orange and black wires, on the main tractor har-
ness. Pull leak detector harness out of the access hole
on the hydraulic tank.
7. Loosen four (4) cap screws securing the valve as-
sembly to the fill neck on the hydraulic tank. Lift leak
detection tank from the hydraulic tank. Remove O--ring
from fill neck boss (Fig. 76).
Installation (Fig. 74)
1. Top off main hydraulic tank until fluid is visible at base
of breather port. This will ensure that the maximum
amount of air is purged from the main tank before instal-
ling the leak detector.
2. Make sure filler screen is placed in neck of auxiliary
tank.
3. Make sure five (5) cap screws and washers securing
the cover plate to auxiliary hydraulic tank are removed
