4. Loosen straps that secure fuel tank to machine
frame (see Fuel Tank Removal in this section). Shift tank
position toward right side of machine to allow access to
upper lift cylinder pivot pin.
5. Remove shoulder bolt and pivot pin that secure up-
per clevis of lift cylinder to frame. Rotate top of lift cylin-
der to allow access to centrifugal clutch.
6. Remove cap screw (item 18) and flat washer (item
17) that secure clutch to engine crankshaft.
7. Loosen drive belt tension and remove drive belts
from centrifugal clutch pulley.
IMPORTANT: To protect the engine crankshaft dur-
ing clutch removal, place thick washer on end of
crankshaft and lightly grease end of clutch puller.
8. Remove clutch from engine crankshaft with clutch
puller (see Special Tools in this Chapter).
Installation (Fig. 8)
1. Thoroughly clean tapers on engine crankshaft and
centrifugal clutch bore.
2. Slide centrifugal clutch onto engine crankshaft.
3. Secure clutch to engine crankshaft with cap screw
and flat washer. Torque cap screw from 270 to 330 in- -lb
(31 to 37 N- -m).
4. Install drive belts to centrifugal clutch and jack shaft
pulley.
5. Adjust drive belt idler pulley to achieve proper ten-
sion on drive belts (see Operator's Manual).
IMPORTANT: After adjusting belt tension, check
that distance from idler pulley face to the faces of
the clutch drive pulley and jack shaft driven pulley
is correct (Fig. 9). This distance is necessary to en-
sure that idler pulley is correctly aligned to drive
belts. If necessary, either adjust position of engine
on machine frame or the driven pulley on jack shaft
(see Jack Shaft Assembly in the Service and Re-
pairs section of Chapter 6 - - Chassis) to allow cor-
rect distance.
IMPORTANT: When securing lift cylinder pivot pin
to frame, there should be clearance between the
shoulder bolt head and pivot pin. Do not overtighten
shoulder bolt.
