Raise the Lifting Fixture so that the CVT assembly weight is mostly supported by the
Lifting Fixture and just slightly raised off of the work surface.

61.

Loosen the side cover with a slide hammer at the three points (tool location marks)
shown in Figure 80.


Rotate between the three (3) locations on the side cover until the CVT case
separates from the sub-assembly. This can take more than one rotation to loosen
the sealant.

To avoid damage to the CVT, DO NOT use a prybar, chisel, etc. to separate the side cover
from the CVT case.
HINT: Apply rust penetrant to the two dowel pins as needed.

Raise the Lifting Fixture to remove the
“side cover with pulleys and belt
assembly” (sub-assembly) from the
CVT case (Figure 81).

To avoid damage to the primary speed
sensor, make sure it is removed from the
sub-assembly.


The speed sensor will be reused.



DO NOT discard the speed sensor.



This sub-assembly will not be
reused.

Remove the lifting fixture from the sub-assembly.


64.

Reinstall all six (6) original bolts into the old sub-assembly.

Thoroughly clean the mating surfaces of the CVT case (Figure 82) that the subassembly was just separated from (a plastic scraper can be used).


Confirm that the dowel pins have remained in the CVT case. If not, remove them
from the sub-assembly and reattach them back to the CVT case.

HINT: The Guide Pins can be temporarily removed for cleaning purposes.
To prevent debris from entering the CVT and causing damage:




DO NOT use sanding discs, similar abrasive tools, or metal blades.
Use brake cleaner or equivalent solvent and lint-free towels only.
Make sure rust and debris have been removed from the dowel pins and receiving
holes.

69.

Apply one continuous 2.0 mm diameter bead of sealant along the center of the CVT
case side mating surface (Figure 88).
Sealant:
 Loctite 5460 (see PARTS INFORMATION on page 92).
 Color: Pink
IMPORTANT:
 Confirm that the mating surfaces are clean before applying sealant.
 Make sure that the starting point and the ending point of the sealant is between
two bolt holes. Overlap both ends of the bead by 3 – 5 mm.

To prevent possible leaks, be careful not to contact or contaminate the sealant. If the
sealant has been disturbed or contaminated in any way before case assembly, thoroughly
clean the mating surfaces of the CVT case and restart from step 69.

Install the original thrust bearing on the primary pulley of the new sub-assembly
(Figure 89).

HINT:


The thrust bearing surface must lay flush with the primary pulley. Any additional
height will affect the total end play that is measured later in this procedure.



The thrust bearing has two sides. Reference Figure 90 for bearing orientation.



Apply a small amount of petroleum jelly or equivalent to the original thrust bearing
to hold it in place on the primary pulley.

Coat the primary pulley bearing, secondary pulley gear teeth, and the secondary
bearing with CVT fluid prior to installation (Figure 91 and Figure 92).

HINT: DO NOT drip any CVT fluid onto the sealant.
The following figures are for reference only and may or may not have the sealant in
place or have the old sealant removed. Clean the surfaces and apply sealant when
and where instructed.

While lowering the sub-assembly, route the Guide Pins into the appropriate CVT bolt
holes, one at a time (the Guide Pins are different lengths for easy assembly).

HINT: DO NOT allow the output gear to contact the lubrication tube when the side cover is
positioned over the guide pins (Figure 93 and Figure 94).

IMPORTANT:
Before continuing, it is recommended that you review and understand the instructions on
pages 48 through 52.
The sub-assembly will lower into the CVT case without applying extra vertical force.
IF THE SUB-ASSEMBLY DOES NOT LOWER COMPLETELY,
INTERFERENCE IS PRESENT.

! PHYSICAL

Key Technique: Raise to remove weight on interference, adjust as necessary, and
then lower again.

Use the “visual gap size” below (Figure 95 and Figure 96), between the sub-assembly and
the CVT case, to determine the cause of interference.

44 mm - Page 49
38 mm - Page 50

73.

Carefully, lower the Lifting Fixture to install the sub-assembly into the CVT case until a
38 mm (1.5 inch) gap is present between the sub-assembly and CVT case. See
Figure 101 on page 50.


Look into the bearing bore to confirm the output gear is centered (Figure 98).



Place hands on top of the sub-assembly to keep it level and guide it into the
CVT case.


If the sub-assembly will not lower farther than 44 mm (1.75 inches) the
output gear did not clear the bearing bore (Figure 97).

Sub-assembly will not lower past 44 mm (1.75 inches)?


Interference is present between the output gear and bearing bore.

In the following steps be careful not to contact or contaminate the sealant or a leak may
occur. If the sealant has been disturbed or contaminated in any way, remove the sealant
completely and restart from step 69 on page 45.
74.

Align the parking rod with the parking pawl as follows:

IMPORTANT: Perform step 74 while there is a 38 mm (1.5 inch) gap between the subassembly and CVT case (Figure 101).
a) Rotate the shift select lever clockwise on the side of the CVT to adjust the parking
rod to the highest position.
b) Use a magnet to align the parking rod in the CVT case (
in Figure 100) with the
opening in the parking pawl (
in Figure 99) in the side cover.
HINT: If the parking rod is not located correctly it will keep the case from lowering.
The following figures are for reference only.

Continue to slowly lower the sub-assembly into the CVT case.


If the primary and the secondary pulley bearings do not align properly with their
bores (Figure 102) or are at an angle, a gap of 19 mm (0.75 inches) may be
present.
 As needed, level the sub-assembly as it is lowered into the CVT case to help
the primary and the secondary pulley bearings align in their bores.
 MINOR LEVELING ADJUSTMENTS with limited weight on the sub-assembly
will help the installation. Vertical force is not needed.
 Once the sub-assembly is LEVEL, the primary and the secondary pulley
bearings will smoothly align while lowering.

Sub-assembly will not lower past 19 mm (0.75 inches)?


If this occurs Do NOT force the sub-assembly into the case.
a. Raise the sub-assembly slightly.
b. Level the sub-assembly (visually check the gap between case and sub-assembly
side cover and confirm that it is even all around).
c. Gently lower the sub-assembly.
d. Gently shake the sub-assembly horizontally, lower, raise and repeat as needed
to help align.
e. Lower to engage the dowel pins and a 6 mm (0.25 inch) gap is between the subassembly and CVT case.

IMPORTANT: In the following steps the case halves must sit flush against each other
without a gap before installing the bolts. The bolts CANNOT be used to draw the cases
together. DO NOT APPLY VERTICAL FORCE.
76.

Once the dowel pins are cleared, ease the sub-assembly down onto the CVT case
until the case halves are flush.


Confirm the dowel pins are clean and aligned and are not catching on the subassembly case cover.

To avoid personal injury, ensure your fingers are not between the CVT case and the subassembly. They may become pinched while seating the components together.
Sub-assembly will not lower past 6 mm (0.25 inches)?
If the sub-assembly will not lower past 6 mm (0.25 inches), the primary pulley splines are
not aligned.


If this occurs Do NOT force sub-assembly into the case.
a. Raise the sub-assembly slightly so the weight is not completely on the primary
pulley splines.
b. Slightly rotate the primary pulley through the bottom of the CVT and then lower
the sub-assembly.
c. Repeat as needed.

Confirm the parking rod operation as
follows:
a. Rotate the shift select lever

counterclockwise and confirm that
all detents for each of the P-R-N-D
are felt.
b. Rotate the lever clockwise to return

the rod back to the P position.
c. Are all of the detents felt?

 YES: Proceed to step 78.
Figure 104
 NO: If the lever does not rotate
or if all detents are not felt:
1) Raise the sub-assembly and remove all sealant.
2) Restart from step 69 on page 45.

78. Remove the guide pins.
