Clean the CVT Surfaces

CAUTION: During the next two steps;


Avoid any debris from dropping into the torque converter housing, side cover or the
CVT case. It is extremely important to keep any debris away from CVT internals to
prevent drivability concerns.



Use brake cleaner to remove the remaining CVT fluid and any residual sealant.



Do not use sanding discs, abrasive tools, or metal blades on sealing surfaces.



To clean dowel pins a mild abrasive sandpaper can be used to remove all rust and
debris.
 This will assist at a later step when mating the CVT Case to the sub-assembly
and again when mating the CVT Case to the torque converter housing.

1. Remove any sealant that remains on the
sealing surface of the CVT case where it
seals with the sub-assembly side cover.


A plastic scraper can be used.



Use ONLY brake cleaner to clean
surfaces.



Clean with a lint-free paper towel.

Clean Oil Passages in CVT Case and Oil Pump Cover
In the following steps:


Brake cleaner and compressed air will be used to clean out oil passages in the CVT
assembly.
WARNING: Wear eye/face protection when using compressed air and cleaning
fluids.
CAUTION: Regulate air pressure up to a maximum of 75 PSI.

1. Confirm the CVT case is on the work
bench with sub-assembly side down.


Use wood blocks as necessary to
stabilize the assembly during these
steps.

CAUTION: Make sure the surface of the
work bench has been cleaned.

2. Spray brake cleaner into each oil passage, indicated in yellow, of the CVT case where
shown in Figure 2L and Figure 3L, until the fluid runs clear for 5 seconds.
IMPORTANT: Do not apply brake cleaner or compressed air to passages shown in
white.
3. Apply compressed air in the same passages to remove remaining cleaner and debris.
NOTE: Do not stand in front of the passages while using compressed air.

Measuring the CVT Sub-assembly Case Depth

Torque converter
housing

1. Temporarily install the torque converter
housing to the CVT case with two (2)
bolts at opposite corners, hand tight
(Figure 1M).


Use original bolts to secure.

Figure 1M

2. Reposition the CVT on the work bench
with the torque converter housing side
facing down (Figure 2M).

for the measuring bar being used. This
can be done either with a set of calipers
or with Digital Depth Gauge (J-50272).
