Additional Checks for Two-Speed Fan
Drives
Check the Two-Speed Mechanism, (while air
is applied to the fan drive) by rotating the fan
and clutch pack in both directions (independent
from the pulley).
• Check for damaged or broken magnets
and for interference between the magnet
assembly and fan mounting disc. If
damaged or broken, repair the fan drive
with the appropriate repair kit, or replace as
needed.
NOTICE
A contaminated air supply may damage
the fan clutch assembly. Anytime system
contamination is present take the
necessary steps to correct the situation
and purge the air lines.
Air Conditioning Refrigerant
• Verify air conditioning refrigerant charge is
at the correct level and the system operates
correctly.
• Capacity 2.4lb +/- .25lb.
Compressor
• Inspect air conditioner compressor base
and mounting for proper attachment, cracks
and evidence of leaks.
System Lines, Hoses and Connections
• Check all air conditioning system lines,
hoses and connections for evidence of
leakage. Current production tractors use
a fluorescent dye in the refrigerant. Use a
black light to look for leaks.
Under Tractor Inspection (300 Hours)
Note: Any fastener or driveline component
with a shiny, metallic appearance, or having
rust streaks, indicates a loose or broken
part.
Driveline
• Check U-joints and slip yokes for free
play during lubrication procedure. Inspect
driveline for loose bolts. Rotate driveline,
checking for excessive play in U-joints (not
to exceed 0.063 in. [1.60 mm]). Check all
driveline fasteners for looseness. Any shiny
area, or rust stains in the driveline indicate
that there is a loose driveline part. Inspect
center bearings for leaks and free play
(0.063 in. [1.60 mm]). Push and pull shaft,
checking for run-out at splines (should be
between 0.063 in. [1.60 mm]).
Engine
• Check engine mounts for cracks and
deterioration.
• Verify all engine mounting fasteners are
tightened to the correct torque.
Transmission
• Check the transmission output bearing
(driveshaft yoke) for movement (Refer to
transmission manufacturer’s documentation
for procedure and specifications).
