Chapter 2- Drive System: CVT and Transfer Case
13
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)
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.
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.
