Clutch Shaft Assembly (Fig. 52)
IMPORTANT: Apply a light coating of multi−pur-
pose ATF to all O−rings and rubber portions of oil
seals during assembly of clutch shaft components.
1. Make sure that all clutch shaft assembly compo-
nents are cleaned before assembly.
2. If removed, assemble clutch actuator (item 23) and
bearing (item 21) to pressure plate (item 20)
A. Lubricate and install O−ring (item 22) into clutch
actuator groove.
B. Install bearing into clutch actuator bore.
C. Use press to install clutch actuator with bearing
onto pressure plate.
3. If removed, press bearing (item 25) into clutch cam
(item 24) and secure with retaining ring (item 26).
4. If removed, install bearing (item 12) onto clutch shaft:
A. Slide bearing spacer (item 14) onto clutch shaft.
B. Use press to install bearing onto clutch shaft.
C. Secure bearing to clutch shaft with retaining ring
(item 10).
5. Install oil seal (item 9) into clutch pulley making sure
that seal is fully pressed to shoulder of pulley bore.
6. Lubricate and install O−ring (item 11) into bearing
bore groove in clutch pulley.
7. Install bearing spacer (item 14) onto clutch shaft and
then press new bearing (item 12) onto shaft. Make sure
that bearing is fully installed onto shaft. Secure bearing
onto shaft with retaining ring.
8. Install clutch pulley onto clutch shaft making sure
that shaft does not damage oil seal already installed in
pulley. Bearing fit into pulley is a slip fit until resistance
will be felt when O−ring in pulley contacts bearing. Once
bearing is fully installed to shoulder of pulley, install re-
taining ring (item 13) to secure bearing.
9. Press bearing (item 7) onto clutch shaft and into
clutch pulley. Bearing should be pressed fully until it con-
tacts shoulder on shaft.
10.Slide bearing spacer (item 6) onto shaft and then
press bearing (item 5) onto shaft.
IMPORTANT: The flocked seal should be installed
so the flocked side of the seal is toward the bearing
location.
Traction and Reel Drive System
11. Slide flocked seal onto clutch shaft with flocked side
orientated toward bearing location. Then, install wave
spring (item 3) and flat washer (item 2) onto shaft and
secure with retaining ring (item 1).
12.Starting with a clutch disc, install complete clutch
pack onto pressure plate (item 20) with attached clutch
actuator (item 23) and bearing (item 21).
13.Slide compression spring (item 16) onto clutch shaft.
14.Install pressure plate assembly onto clutch shaft and
align tabs on clutch disc with slots in clutch pulley. As
pressure plate is installed, compression spring will be
compressed.
15.Use a suitable hand clamp to keep pressure plate
(item 20) and clutch pulley housing (item 8) secured and
spring compressed.
16.Slide clutch cam (item 24) with bearing onto end of
clutch shaft. Make sure that ramps of clutch cam align
with ramps of clutch actuator (Fig. 54).
17.To allow installation of flange head screw (item 26)
that secures clutch assembly to shaft, carefully secure
end of clutch shaft in vise. Use a vise with soft jaws to
prevent damage to clutch shaft.
18.Secure clutch shaft assembly with washer and
flange head screw (item 26).
19.Remove hand clamp from clutch shaft assembly.
20.After clutch shaft assembly, make sure that clutch
plates can be moved between pressure plate and clutch
pulley. The clutch should be disengaged when the clutch
shaft assembly has been properly assembled.
