a. Removal (Refer to Figure 2-13)
(1)
Loosen two bolts (1) and one nut (2) securing hydraulic pump mount (3) to hydraulic pump
mount (4).
(2) Loosen nut (5) on J bolt (6) to relieve tension on belt (7).
NOTE
Note position of face plate during removal. Plate holes are not evenly spaced and will align in
only one position.

b. Installation (Refer to Figure 2-13)
(1)
Position belt (7) on pump pulley (10) and crank pulley (13).
NOTE
Install face plate as noted during removal.
