Loosen the side cover with a slide hammer at the 3 points shown in Figure 81.


Rotate between the 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.
IMPORTANT: DO NOT use a pry-bar, chisel, etc. to separate the side cover
from the CVT case.
HINT: Apply rust penetrant to the two dowel pins as needed.

Coat the primary pulley bearing, secondary pulley gear teeth and the secondary

IMPORTANT: Do NOT apply sealant to the case at this time. The sub-assembly will
be sealed later in this procedure.

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.

Position the new sub-assembly over the CVT case and then lower it just far enough to
allow the Guide Pins to be inserted into their appropriate sub-assembly holes (the
Guide Pins are different lengths).
IMPORTANT: Do NOT allow the output gear to contact the lubrication tubes when the
side cover is positioned over the guide pins.

IMPORTANT:
Before continuing, it is recommended that you review and understand the instructions on
pages 42 to 47.


Confirm dowel pins are clean – this will ease installation.



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 the sub-assembly to remove weight from the interference,
adjust as necessary, and then lower again.
Use the “gap size” between the sub-assembly and the CVT case to determine the cause of
interference. At any given gap, only 1 item will be the cause of interference.

Carefully lower the Lifting Fixture to install the sub-assembly into the CVT case as
follows:


While visually looking down into the bore (Figure 95) to confirm that the output
gear is clearing the CVT case bearing bore,
a. Level the sub-assembly by placing hands on top to guide it into the CVT case.
b. Lower the sub-assembly until a gap of 40 mm (1.6 inch) is present to the CVT

case (Figure 98 on page 44) and then proceed to step 70.
 If the sub-assembly will not lower any farther than 50 mm (2 inches) the
output gear has not cleared the bearing bore (Figure 95).

Sub-assembly will not lower past 50 mm (2 inches)?
o Interference is present between the output gear and bearing bore and are
highlighted with yellow in Figure 94 and Figure 95.

Install the parking rod into the parking pawl of the CVT sub-assembly as follows:
IMPORTANT: Perform step 70 while the sub-assembly has a 40 mm gap (1.6 inch)
to the CVT case (Figure 98).
a. Rotate the shift select lever clockwise on the side of the CVT to adjust the park

rod to the highest position.
b. Use a magnet, or similar tool, to align the parking rod in the CVT case (

Figure 97) with the opening in the parking pawl (

in
in Figure 96) in the side cover.

HINT:
o If the parking rod is not located correctly it may keep the case from lowering.
o If the parking rod is not located correctly, the shift select lever will not rotate
through all detents (P-R-N-D-L) once the sub-assembly is completely installed.

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 99) or are at an angle, a gap of 18 mm (0.7 inch) may be present.



Possible areas of interference are highlighted with orange and tan in Figure 99.
o 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.
o MINOR LEVELING ADJUSTMENTS with limited weight on the sub-assembly
will help the installation. Vertical force is not needed.
o Once the sub-assembly is LEVEL the primary and the secondary pulley
bearings will smoothly align while lowering.

Sub-assembly will not lower past 18 mm (0.7 inch)?


If this occurs Do NOT force sub-assembly into case.
a. Raise the sub-assembly slightly.
b. Level the sub-assembly (visually check the gap between case and subassembly 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 6 mm (0.25 inch) to clear the dowel pins.

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.
72.

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 the risk of minor personal injury or property damage, be
careful not to get fingers caught between the CVT case and sub-assembly when
seating.

Sub-assembly will not lower past 5 mm (0.2 inch)?
If the sub-assembly will not lower past 5 mm (0.2 inch), the primary pulley splines are
interfering with the planetary carrier splines.


If this occurs Do NOT force sub-assembly into case.
a. Raise the sub-assembly slightly to separate the primary pulley and the
planetary carrier splines to remove interference.
b. Slightly rotate the primary pulley back and forth slowly, through the bottom of
the CVT, and then lower the sub-assembly.
c. Repeat as needed.

Remove Side Cover and Install Lubrication Caps
IMPORTANT: In the following steps, use only a slide hammer and hands to separate the
side cover.
In the following steps, if the side cover does not easily lift off by hand
it is still
seated on the pulley bearings and must first be completely separated.

Do NOT use tool J-52275 at this time.

75.

Install two Pulley Bracket Guide Pins
(J-52272).


76.

The bracket guide pins will be used
as a height marker of the pulleys to
ensure they remain seated in the
case as the side cover is removed.

Pulley Bracket Guide
Pins (J-52272)

Use slide hammer (J-25721-A) with Jhook case separator (J-51923) and
evenly separate the side cover from
the belt and pulley assembly.


Alternate between the three
hooking locations on the side
cover until the side cover
separates from the pulleys (see
page 37 Figure 81).
o As the side cover is raised up,
the exposed height of the
pulley guide pins will shorten.
This is an indicator that the
pulleys are remaining seated in
the CVT case.

o Make sure the side cover is
completely separated from the

o Once the side cover is
separated from pulley bearings,
it will rock freely and can be
easily lifted by hand.
IMPORTANT: Use only a slide
hammer and hands to separate the
side cover from the pulleys.

Install two (2) new lubrication caps (see PARTS INFORMATION) shown in Figure
105 onto the tubes of the CVT case shown in Figure 106 as follows:
a. Insert the lubrication caps through the slots in each chain guide.
b. Face the larger side of the “wedge shaped index guide” away from the pulleys.
c. Gently push each lubrication cap down into the square cut seat of the CVT case
tubes.
HINT: Slightly rotating the lubrication caps will help in aligning them into the
square cut seats.
IMPORTANT: Confirm that the caps are installed in the correct orientation.
