4. Position cover mounts (items 27 and 28) to frame.
Align bearing flanges and cover mounts to frame. Se-
cure bearings and mounts to frame with four (4) cap
screws, eight (8) flat washers and four (4) lock nuts.
5. Rotate jack shaft a few times to align bearings. Posi-
tion jack shaft so that end of jack shaft on drive side
(clutch side) extends 6.100" to 6.340" (154.9 to 161.0
mm) from bearing mounting plate (Fig. 13).
6. Secure jack shaft in bearings (see Flange Bearing
Service in this section).
IMPORTANT: When installing pulleys and drive
belts, make sure to properly align drive, driven and
idler pulleys.
NOTE: When installing pulley on right end of jack shaft
(driven side), align pulley and drive belt with drive pulley
on centrifugal clutch. When installing pulley on left end
of jack shaft (drive side), align pulley and drive belt with
driven pulley on chopper axle.
7. Install square key, pulley, taper lock bushing and
drive belt to both ends of jack shaft (see Pulley Assem-
bly Service in this section).
8. Adjust drive belt idler pulleys 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 drive and driven pulleys is correct (Figs. 14 and
15). This distance is necessary to ensure that idler
pulley is correctly aligned to drive belts. If neces-
sary, re- -adjust positions of drive and driven pulleys
to allow correct distance.
9. Secure jack shaft cover (item 22) to machine.
10.Install belt covers (see Drive Belt Covers in this sec-
tion).
