4.16. The ratio change should be fully accomplished
by 3,000 RPM. Beyond this speed, increases in
vehicle speed are directly proportional to
increases in engine speed. See Figure 4.16.
Figure 4.16
NOTE: In Figure 4.16 the belt is drawn fully into
the driven pulley by the squeezing action of driv-
ing pulley.
4.17. When engine speed is drawn below 3,000 RPM
by a heavy load and/or steep grade, the CVT
pulleys automatically begin to change ratios to
increase available power to the wheels.
4.18. Alignment: correct spacing and alignment of
the engine and transaxle is set at the factory
using special fixtures.
4.19. The transmission is mounted to brackets that
allow little room for adjustment.
4.20. The holes for the engine mounting bolts are
over-sized to accommodate adjustment.
4.21. If belt drag, accellerated belt wear, or loss of top
speed are noticed, particularly after service that
requires engine removal, check the alignment
and spacing.
4.22. Spacing is correct when belt drag torque is cor-
rect, as described in paragraph 4.3.
4.23. Alignment can be done visually, using a straight-
edge.

CVT REMOVAL: DRIVEN PULLEY
To remove the driven pulley, begin by removing
the bolt that holds it to the input shaft of the tran-
saxle using a 3/4" wrench.
NOTE: If an impact wrench is not available, it
may be necessary to manually place the trans-
mission in Forward gear and set the parking
brake.
Carefully roll the drive belt off of the driven pul-
ley. See Figure 5.2.

Slide the pulley off of the input shaft. It may be
necessary to carefully pry on the pulley hub.
