Drive System Adjustments; Cvt Service; Belt Removal - Cub Cadet 6X4 Shop Handbook

DRIVE SYSTEM ADJUSTMENTS:

1. CVT spacing and alignment:
• Spacing and alignment are critical to proper CVT
performance and belt longevity.
• In normal service, these items should not be an
issue on this vehicle. The engine and transfer
case are firmly tied to each-other by the engine /
transmission plate that holds proper spacing and
alignment.
2. Adjustment of the driving element and driven
element:
• The CVT is tuned to maximize performance of
the vehicle. It should require no adjustment in its
normal service life.
• While it is mechanically possible to disassemble
the driving and driven elements, individual parts
will not be available through Cub Cadet.

BELT REMOVAL

NOTE: The procedure to remove the belt is the
same for the Kohler and the Caterpillar engines.
1a. When new, the belt measures 1.335"
+.031" (33.9 + .8mm) across the wide flat
outside surface of the belt. The belt is
considered worn when the measurement
is 1.20" (30.5mm) or less. some degrada-
tion of performance may begin to occur as
belt is worn to less than 1.275" (32.4mm).
See Figure 2.9.
New: 1.335"
(33.9mm)
Worn: 1.20"
(30.5mm)

Chapter 2- Drive System: CVT and Transfer Case
1b. To remove the belt, a 6mm/1.0 screw with a
minimum thread length of 1.15" (2.9cm)
will be required. See Figure 2.10.

thread length
NOTE: A 6mm screw with a thread pitch of 1.0
may be purchased locally. The minimum thread
length needed is longer than the threads of a
standard screw of this size. It will be necessary
to cut threads further up the shank of the screw
using a thread-cutting die.
1c. There are 4 holes in the face of the driven
element. Three of them are close
together, one is 180 degrees away from
the others. The middle hole of the set of
three is threaded.
See Figure 2.11.
