Clean the CVT Case Surfaces

34.

Thoroughly clean the mating surfaces of the CVT case and torque converter housing.


A plastic scraper can be used.

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 towel only.
 Make sure rust and debris have been cleaned off of dowel pins and receiving
holes (Figure 55 and Figure 56).

35.

Clean the dowel pins and dowel pin receiving holes of any rust and debris (Figure 55
and Figure 56).
HINT: Use a small wire brush or similar tool at the inside surface of the dowel pin
holes. DO NOT SCRAPE THE CVT CASE mating surfaces.

Clean the Oil Passages in the CVT Case, Oil Pump Cover, and CVT Filter Area

In the following steps, brake cleaner or a suitable cleaning solvent and compressed air will
be used to clean out the oil passages in the CVT assembly.

To prevent debris from entering your eyes and causing personal injury, wear eye / face
protection when using compressed air and cleaning fluids, and regulate the air pressure up
to a maximum of 75 PSI.

36.

Clean the area where the CVT fluid
filter fits (Figure 57).

this area

Make sure the old filter grommet
seal is removed (Figure 54).

Clean the fluid passages to and from
the filter (Figure 57).

Do not spray brake cleaner into the clutch pack.

Apply compressed air in the same passages.

To avoid being struck by debris, do not stand in front of the passages while using
compressed air.

Replace the Side Cover – Pulleys and Belt (sub-assembly)

Review video # 547: “CVT Belt and Pulley Replacement” and fast forward to minute
marker 3:14. This video is located under the TECH TRAINING GARAGE VIDEOS tab
in Virtual Academy.

Temporarily install the dummy cover
with three (3) bolts, finger tight
(Figure 64).
IMPORTANT:




Do not install the thrust bearing to
the clutch assembly bore at this
time.
If the cover does not sit flush,
continue to Dummy Cover
Troubleshooting, below.
Otherwise, skip to step 53.

Dummy Cover Troubleshooting


If the dummy cover does not sit flush, the clutch pack may not be fully seated.



Figure 65 shows the clutch pack
fully seated.



The clutch pack is not fully seated
if it is not below the surface that the
dummy cover bolts to.



To fully seat the clutch pack, follow
the instructions in steps 47-51.

Clutch pack

HINT: Always handle the clutch pack by
the input shaft.

Gently jiggle the input shaft until the
clutch pack seats below the case lip.


If the clutch pack does not seat,
rotate back and forth from the input
shaft and jiggle.



If the clutch pack still does not
seat, repeat from step 48.

Temporarily install the converter
housing onto the CVT case with three
(3) bolts finger tight (Figure 70).
Bolts

To prevent CVT damage when fitting the
CVT case surfaces, DO NOT use the bolts
to draw in the case halves. Make sure the
case surfaces are flush and have no gaps
prior to installing the bolts.

CVT lifter bracket J-51595 and
CVT Lifting Eye/Swivel Assembly
J-51595-1 can be used for this
step. See Figure 72.

Use plastic or wood blocks to
support the CVT while rotating to
prevent contact with the manual
shaft and damage to the CVT
(Figure 71). The manual shaft is
longer than the oil pan mating
surface.

To avoid damage to the CVT, note
the location of the terminal
connector harness so that the
terminal connector harness does
not become pinched between the
CVT case and the work bench or
supporting blocks.

IMPORTANT: Remember the pulley’s
rotational characteristics. This will be
used as a reference after the new side
cover pulleys and belt assembly (subassembly) have been installed.

HINT: When working with the sub-assembly install, uninstall, and bracket attachment, it is
critical that the CVT and sub-assembly are level. If not level, the pulleys and bearings can
sit slightly at an angle and will hinder installation.

a. Loosen all of the wing-nut bolts on the Lifting Fixture.
b. Confirm that three (3) spacers (# J-52082-2) are present between the longer legs
and triangle bracket as shown in Figure 79.
c. Install the Lifting Fixture to the CVT case at the six (6) bolt holes shown in Figure
78.
d. Tighten the wing-nut bolts on the Lifting Fixture finger tight in the following order:
1. Tighten the lower six (6) wing-nut bolts.
2. Tighten the two (2) joint to triangle brackets.
3. Tighten the top two (2) wing-nut bolts, and then proceed to step 60 on the next
