Removal (Fig. 88)
1. Before removing any parts from the hydraulic sys-
tem, park machine on a level surface, set brake, lower
cutting units, and stop engine.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components.
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.
4. Remove five cap screws and flat washers securing
the cover plate and cap tether to the leak detection tank.
Remove cover plate from tank (Fig. 89).
5. Remove cap screw and flat washer securing R--
clamp and leak detector harness to the underside of the
hydraulic tank. Pull clamp free of harness (Fig. 90).
6. Unplug leak detector harness from 2--pin plug, with
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 cap screws securing the valve assem-
bly to the fill neck on the hydraulic tank. Lift leak detec-
tion tank from the hydraulic tank. Remove O--ring from
fill neck boss (Fig. 90).
Installation (Fig. 88)
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 capscrews and washers securing
the cover plate to auxiliary hydraulic tank are removed
with the cover plate (Fig. 89).
4. Clean mating surfaces of block and fill neck with a
clean, dry rag. Carefully place new O--ring over fill neck
boss (Fig. 90).
