Leveling Procedure; Reel Bearing; Fan Belt - Jacobsen Greens King IV PLUS Service Manual

3.13 LEVELING PROCEDURE ____________________________________________________

1. Lower the implements until they are about 1/4 in.
(6.35 mm) above the ground. If they are not level
with the ground, adjust torsion spring (Z).
!
WARNING
The torsion spring is under extreme tension and will
tend to uncoil very rapidly if the clamp is loosened. To
prevent being cut by clamp or spring, unwind spring
by tapping on clamp while slowly loosening nut.
2. Carefully loosen spring mounting clamp and slowly
turn clamp until implement is level. Tighten clamp
securely.

3.14 REEL BEARING ___________________________________________________________

Excessive end play or any radial play indicates bad
bearings, a weak tension spring, or a backed off nut.
1. Check bearing housing mounting hardware. Tighten
or replace components as required. Carefully clean
threads with degreaser.
2. Apply a medium strength grade of Loctite to nut (AA),
then thread nut onto the reel shaft until the nut is
1-27/32 in. (46 mm) from the end of the reel shaft.
3. Fill reel bearing housings with NLGI - Grade O
grease after adjusting spring.

3.15 FAN BELT ________________________________________________________________

Inspect and adjust new belt after first ten hours of
operation. Adjust every 100 hours thereafter.
1. Adjust alternator pulley so belt (B) deflects 9/32 to
11/32 in. (7 to 9 mm) with a 22 lb. (10 kgf) push at
mid span between pulleys.
2. If tension is incorrect, loosen alternator mounting
bolts (A) and adjust alternator until proper belt
tension is achieved. Tighten hardware (A).
