5. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
6. Disconnect hydraulic lines from gear pump and put
caps or plugs on open hydraulic lines and fittings. Label
disconnected hydraulic lines for proper assembly (Fig.
51).
7. Support gear pump assembly to prevent it from fal-
ling.
8. Remove two (2) cap screws and washers securing
gear pump to piston pump. Remove gear pump, coupler
(item 9), spacer (item 17) and O- rings (item 16) from
machine.
9. If hydraulic fittings are to be removed from gear
pump, mark fitting orientation to allow correct assembly.
Remove fittings from pump and discard O- rings.
Installation (Fig. 50)
1. If fittings were removed from gear pump, lubricate
and place new O- rings onto fittings. Install fittings into
pump ports using marks made during the removal pro-
cess to properly orientate fittings. Tighten fittings (see
Hydraulic Fitting Installation in this chapter).
2. Lubricate new O- rings (item 16) with clean hydraulic
oil. Position O- rings on gear pump and pump spacer
flanges.
3. Slide coupler (item 9) onto the piston pump output
shaft.
4. Position pump spacer (item 17) to gear pump. Align
gear teeth and slide gear pump input shaft into coupler.
Secure gear pump to piston pump with two (2) cap
screws and flat washers.
5. Remove caps and plugs from hydraulic hoses and
fittings. Install hoses to gear pump (see Hydraulic Hose
and Tube Installation in this chapter).
6. Replace hydraulic filter and fill hydraulic reservoir
with new hydraulic oil (see traction unit Operator's Man-
ual).
7. Prime hydraulic pumps (see Priming Hydraulic
Pumps in this chapter).
8. Charge hydraulic system (see Charge Hydraulic
System in this section).
9. Stop engine and check for hydraulic oil leaks. Check
hydraulic reservoir oil level.
10.Lower and secure seat.
