Removal (Fig. 29)
1. Remove operator seat from machine (see Operator
Seat Removal in this section).
2. Remove armrest assemblies and then back panel
from back of seat.
3. Carefully peel label from back rest knob (Fig. 30).
Remove nut and knob from seat frame.
4. Remove six (6) x–mas tree clips that secure back
cushion to seat frame. Remove back cushion.
5. Remove two (2) cap screws that secure bottom
cushion to seat frame. Remove bottom cushion.
6. Remove hex nut that secures weight adjustment
knob to weight adjust bar. Remove adjustment knob
from weight adjust bar to remove cable tension. Re-
move cables from spring saddle.
7. Remove eighteen (18) x–mas tree clips from seat
frame to separate seat boot from frame.
8. Remove two (2) roll pins that secure bearing shafts
to seat frame. Remove bearing shafts and split nylon
bushings from frame.
9. Lift seat frame from suspension base.
10.Remove nut and bolt that secure top of shock ab-
sorber to suspension base.
11. Slide spring saddle from spring arm while disengag-
ing springs at top of suspension base.
12.Remove springs from spring saddle. Pay close
attention to orientation of springs and spring saddle for
assembly purposes.
13.Remove nut and bolt that secure bottom of shock ab-
sorber to spring saddle. Remove shock absorber.
Installation (Fig. 29)
1. Secure bottom of shock absorber to spring saddle
with nut and bolt.
2. Attach springs to spring saddle in the same orienta-
tion noted during removal.
3. Position spring saddle on spring arm and slide down.
Hook spring ends on top of suspension base.
4. Using the suspension base as a pry point, place a
prybar on the top of the spring saddle and push saddle
down to elongate springs enough to allow installation of
the bolt to the top of shock absorber and suspension
base. Secure bolt in position with nut.
5. Position seat frame to suspension base.
6. Align bearing blocks on frame with receivers on sus-
pension base and guide frame into place. Insert two (2)
bearing shafts and split nylon bushings to suspension
base and frame. Secure bearing shafts with two (2) roll
pins.
7. Position cables under the seat frame bars and on top
of suspension base. Insert cable ends in spring saddle
slots.
8. Pass weight adjustment knob shaft through weight
indicator, washer and seat frame hole. Thread knob
shaft into weight adjust bar. Install hex nut on knob shaft.
9. Position seat boot to seat frame and secure with
eighteen (18) x–mas tree clips.
10.Position bottom cushion to seat frame and secure
with two (2) cap screws.
11. Position back cushion to seat frame and secure with
six (6) x–mas tree clips.
