An extremely bad axle bearing can mimic a
dragging brake. If the axle shaft does not run
concentric to the axle tube that the brake is
mounted to, the brake drum will rub on the shoes
when the brakes are fully released. This will pro-
duce sluggish vehicle response and a grinding
noise from the bearing.

If the problem lies within the external shift mech-
anism or the controls, diagnostic procedures can
be found in the 2004 Cub Cadet Technical Ser-
vice Disc.(Form # 769-00961).

If the gears can be shifted manually (or using the
the gear selector buttons) with the engine off,
but are difficult to shift with the engine running,
there may be excessive belt drag on the input
pulley. Loading the input shaft can bind the
gears, creating too much friction for the shift
mechanism to over-come.

4 X 2 Drive System - (Steel Bed)
DIAGNOSIS AND SERVICE: DRIVE BELT
AND CLUTCHES (CVT OR CONTINUOUSLY
VARIABLE TRANSMISSION)
Park the vehicle on a firm level surface, with the
ignition turned off, and lift the load bed to provide
access to the drive system.
Inspect the belt and clutches (pulleys) for obvi-
ous damage and wear. The belt should measure
at least 1.10 (27mm) across the outside (wide)
surface. If it measures less than this it is worn,
and should be replaced. Confirm that the cor-
rect belt is on the vehicle: Cub Cadet Part # 754-
04018A. The outside of the belt should be flat,
not ribbed.
With the transaxle in neutral, it should be possi-
ble to rotate the driven pulley (on the transaxle)
without applying a force of more than 20 inch-
lbs. to the driving pulley (on the engine). The belt
should slip easily on the driving pulley.
See Figure 4.3.
Figure 4.3
A torque wrench with a 3/4" socket on it should
read less than 20 in.-lbs. while rotating the input
shaft.
If this figure is exceeded, remove the belt and
repeat the test. This will confirm if the bind is
internal or external.
If the problem is internal, examine the transaxle,
if the problem is external, examine the CVT.
With the vehicle in neutral, insure that no unsafe
conditions will arise from starting the engine.
Connect at tachometer to the engine.
