NOTE: The front frame needs to be lowered from the<br />
main frame to allow clearance to remove the hydraulic<br />
reservoir from the machine.<br />
Removal (Fig. 47)<br />
1. Park machine on a level surface, lower cutting deck,<br />
stop engine, engage parking brake and remove key<br />
from the ignition switch.<br />
2. Remove front cutting deck (see Cutting Deck Removal<br />
in the Service and Repairs section of Chapter 8<br />
-- Cutting Deck).<br />
3. Read the General Pre<strong>caution</strong>s for Removing and<br />
Installing Hydraulic System Components at the beginning<br />
of the Service and Repairs section of this chapter.<br />
4. Drain reservoir into a suitable container.<br />
5. Disconnect hydraulic hoses from reservoir. Label<br />
disconnected hydraulic lines for proper installation.<br />
6. Remove straps (items 4 and 8) that secure reservoir<br />
to front frame. Remove felt straps (item 3) from between<br />
straps and reservoir.<br />
7. To allow front frame to be lowered for reservoir removal,<br />
remove hydraulic tubes that connect hydraulic<br />
components on front frame (wheel motors and front<br />
deck PTO manifold) to components on main frame. Put<br />
caps or plugs on open hydraulic lines and fittings.<br />
8. Chock rear wheels to prevent the machine from moving.<br />
Use jack or hoist to raise front of machine and support<br />
machine with jackstands.<br />
9. Support front frame to prevent it from moving.<br />
10.Remove cap screws (item 31), flat washers (item 28)<br />
and flange nuts (item 30) that secure front frame to main<br />
frame.<br />
11.Carefully lower front frame assembly to allow clearance<br />
for reservoir removal. Once lowered, support front<br />
frame to prevent it from shifting.<br />
12.Carefully remove hydraulic reservoir from machine.<br />
Inspection<br />
1. Clean hydraulic reservoir and suction strainer with<br />
solvent.<br />
2. Inspect for leaks, cracks or other damage.<br />
Installation (Fig. 47)<br />
1. Using a wrench, turn tank strainer into port at least<br />
1--1/2 to 2 full turns beyond finger tight.<br />
2. Position reservoir to machine.<br />
3. Carefully raise front frame assembly to main frame.<br />
Align frame mounting holes and support front frame to<br />
prevent it from moving.<br />
4. Secure front frame to main frame with cap screws<br />
(item 31), flat washers (item 28) and flange nuts (item<br />
30).<br />
5. Lower machine to ground.<br />
6. Position felt straps (item 3) between straps and reservoir.<br />
Secure reservoir to front frame with straps (items<br />
4 and 8).<br />
7. Remove caps and plugs from hydraulic lines and fittings<br />
that were placed during the removal process. Using<br />
labels placed during removal, connect hydraulic<br />
hoses and tubes to fittings on reservoir, wheel motors<br />
and hydraulic manifold (see Hydraulic Hose and Tube<br />
Installation in the General Information section of this<br />
chapter).<br />
8. Install front cutting deck (see Cutting Deck Installation<br />
in the Service and Repairs section of Chapter 8 --<br />
Cutting Deck).<br />
9. Fill reservoir with new hydraulic fluid to proper level.<br />
10.Properly fill hydraulic system (see Charge Hydraulic<br />
System in this section).<br />
11.Stop engine and check for hydraulic oil leaks. Check<br />
hydraulic reservoir oil level.<br />
