Groundsmaster 4100--D Hydraulic SystemPage 4 -- 65
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
-- Cutting Deck).
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. Chockrear wheels toprevent themachinefrom 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 capscrews (item31), flatwashers (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
1--1/2 to 2 full turns beyond finger tight.
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
4 and 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 --
Cutting Deck).
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.
