Removal (Fig. 49)
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 a clean container, large enough to collect 2
gallons (7.6 liters), under the hydrostat to collect hydrau-
lic oil.
3. Clamp pump inlet hose to control drainage. Remove
pump inlet hose from hydrostat. Release clamp from
hose and drain about 2 gallons (7.6 liters) from the hy-
draulic tank (Fig. 50).
4. Clamp pump inlet hose to prevent draining addition-
al hydraulic oil.
5. Remove cap screw (31) and flat washer(30) secur-
ing the tether (29) to the auxiliary tank.
6. Unplug leak detector harness from the main tractor
harness.
7. Remove four cap screws (6 and 9), flat washers (4),
neoprene washers (3), and spacers (3 and 10).
8. Loosen either hose clamp (26) and disconnect over-
flow hose (27).
9. Lift auxiliary tank slightly, loosen hose clamp (13),
and disconnect valve hose (32) at valve fitting. Remove
auxiliary tank assembly.
10. If valve removal is necessary, loosen hose clamp
(13) and disconnect tank hose (23) at hydraulic tank fit-
ting (14). Remove two cap screws (25) and lock washers
(24) securing the valve assembly to the hydraulic tank
and remove the valve assembly.
Disassembly and Inspection (Fig. 49)
1. The leak detector can be disassembled using the
leak detector assembly drawing (Fig. 49) as a guide.
2. Inspect parts for the following:
A. Leaking, cracked, or damaged auxiliary tank.
B. Worn or leaking hydraulic hoses. Replace if nec-
essary.
C. Visibly worn or damaged parts.

PUMP INLET HOSE
Assembly (Fig. 49)
1. Coat all O–rings with clean hydraulic oil.
2. Secure sight gauge (11) and new O–ring (12) to the
auxiliary tank. Torque gauge from 100 to 125 in–lb (11.3
to 14.1 Nm).
3. Secure hydraulic barb fittings (28) and new O–ring
(15) to the auxiliary tank. Torque fitting from 17 to 21 ft–
lb (23 to 28 Nm).
4. Secure valve hose (32) to the barb fitting (28) with
hose clamp (13).
5. Secure both hydraulic barb fittings (14) and O–rings
(15) to the valve body (22)
Installation (Fig. 49)
1. Connect tank hose (23) and install valve assembly
if previously removed.
2. Connect pump inlet hose to hydrostat (Fig. 50).
3. Connect overflow hose (27).
4. Position auxiliary tank over hydraulic tank and con-
nect valve hose (32).
IMPORTANT: Do not over tighten cap screw.
Threads in tank may become damaged.
5. Install four spacers (3 and 10), neoprene washers
(3), flat washers (4), and cap screws 6 and 9). Tighten
cap screws from 30 to 60 in–lb (3.4 to 6.8 Nm).
6. Connect leak detector harness to main wire har-
ness.
7. Secure tether to the auxiliary tank with cap screw
(31) and flat washer (30).
Note: Monitor hydraulic fluid level in sight glass. As air
is removed from the hydraulic circuit, auxiliary tank may
need to be topped off after initial fill.
