Removal (Fig. 76)
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 hydraulic pump assembly
to collect hydraulic oil.
3. Clamp pumpinlethose tocontrol drainage.Remove
inlethosefromgearpump(Fig.77).Releaseclampfrom
hose and drain about 2 gallons (7.6 liters) from the hy-
draulic reservoir.
4. Clamppumpinlethosetopreventdrainingadditional
hydraulic oil.
5. Unplug leak detector solenoid harness from the ma-
chinewireharness.
6. Remove four (4) cap screws (items 14 and 17), flat
washers (item 13), neoprene washers (item 12) and
spacers (items 11 and 18).
7. Carefully position carboncanisterand bracket away
from leak detector tank.
8. Loosen e ither hose clamp (item 9) and disconnect
overflow hose (item 25).
9. Lift leak detector tank slightly, loosen hose clamp
(item 1) and disconnect valve hose (item 10) at barb fit-
ting (item31) onsolenoidvalve assembly. Removeleak
detector tank assembly.
10.If necessary, remove solenoid valve assembly, fit-
tings and hoses using Figure 76 as a guide.
11.I f needed, disassemble solenoid valve manifold us-
ingFigure78asaguide.
12.Inspect leak detector components for the following:
A. Leaking,crackedor damagedleakdetectortank.
B. Worn or leaking hydraulic hoses. Replace if nec-
essary.
C. Visibly worn or damaged parts.
