CHAPTER 2- DRIVE SYSTEM: CVT AND TRANSFER CASE
DRIVE SYSTEM: SERVICE INTENT
1.
The transfer case is manufactured by Cub
Cadet. If it fails during the first two years, it
should be removed and replaced as a complete
unit.
•
In the event of a failure, the transfer case will be
called back for engineering analysis.
•
If the failure is warrantable, Cub Cadet will cover
the cost of replacement.
•
If the failure is not warrantable, replacement will
be at the customer's expense.
•
Beyond the warranty period, internal parts will be
made available so that the dealer can repair or
replace the transfer case at their own discretion.
2.
The remainder of the drive system (CVT, drive
shafts, axles, differentials) is purchased from
outside vendors.
•
If any of these items fail in the first two years,
they should be removed and replaced with a
complete unit.
•
In the event of a failure, the component will be
called back for engineering analysis and vendor
recovery.
•
If the failure is warrantable, Cub Cadet will cover
the cost of replacement.
•
If the failure is not warrantable, replacement will
be at the customer's expense.
•
Drive system components other than the CVT
and transfer case are covered in greater depth in
the Drive shafts, Axles, and Differentials chapter
of this manual.

CVT AND TRANSFER CASE OPERATION
1.
The transfer case contains a relatively conven-
tional three-shaft gear-set providing Neutral,
Reverse, Forward, and Forward Low-range.
2.
The variation in drive speed within each gear is
created by a combination of engine RPM and a
CVT belt drive system.
3.
The CVT belt drive system consists of :
See Figure 2.1.
•
Driving element = driving pulley = centrifugal
torque converter mounted to the crankshaft.
•
Driven element = driven pulley = pulley sheaves
mounted to the input shaft of the transfer case
that react to the motion of the driving element.
•
A special belt that transfers power from the driv-
ing element to the driven element.

4.
Common parts:
4a.
The belt and driven element are the
same on both models of the current Cub
Cadet 4X4.
4b.
The driving elements are different for
gas and diesel versions. The gas engine
and diesel engines have different torque
curves and maximum operating speeds.
