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