4. Place key into piston pump shaft slot. Slide taper lock
bushing onto the piston pump shaft with bushing flange
toward pump housing.
5. Make sure that tapered surfaces of pump pulley and
taper lock bushing are thoroughly clean (no oil, grease,
dirt, rust, etc.).
6. Position pump pulley to taper lock bushing and align
non−threaded holes of pulley with threaded holes of
bushing. Loosely install three (3) cap screws with lock
washers to bushing and pulley.
CAUTION
Support pump assembly during installation to
prevent them from falling and causing personal
injury or component damage.
7. Position pump assembly to the machine. Install fas-
teners and spacers securing the pump mount plate to
the engine and pump support (Fig. 47). Tighten fasten-
ers securely.
8. Position and secure pump support to pump mount
plate, piston pump and engine mount with removed fas-
teners and spacers.
9. Install pump drive belt (see Drive Belt Installation in
this chapter).
10.Using a straight edge across the lower face of the
pump pulley, verify pump drive belt alignment across en-
gine and pump pulleys. Slide pulley and taper lock bush-
ing on pump shaft so that drive belt and straight edge are
aligned indicating correct position of pump pulley. Se-
cure taper lock bushing in position with set screw.
IMPORTANT: When tightening taper lock bushing
cap screws, tighten in three (3) equal steps and in a
circular pattern.
11.Secure taper lock bushing and pump pulley by tight-
ening three (3) cap screws to a torque from 90 to 120
in−lb (10.2 to 13.6 N−m) in three (3) equal steps and in
a circular pattern.
12.Check that pump drive belt alignment is still correct.
If needed, loosen and re−adjust pulley and taper lock
bushing location on pump shaft to allow for correct belt
alignment.
13.Remove caps and plugs from all fittings and hydraul-
ic hoses. Using labels placed during pump removal,
properly connect hydraulic lines to pump assembly (see
Hydraulic Hose and Tube Installation in this chapter).
14.Install neutral arm assembly to the piston pump (see
Neutral Arm Installation in this chapter).
15.Fill hydraulic tank with new hydraulic fluid.
16.Properly charge hydraulic system (see Charge Hy-
draulic System in this chapter)
17.Adjust traction drive for neutral (see Traction Unit
Operator’s Manual).
18.Lower and secure hood.
