WARNING: This page is about a different variant/trim than selected.

CAUTION: Never allow any chemicals or fluids other than NS-3 CVT fluid or equivalent to enter the CVT assembly. Never allow any foreign debris, dust, dirt, etc. to enter the CVT assembly.

Secure the right front tire with a suitable strap . This will assist in making the chain belt turn.

Mark the left front tire with a suitable marking. This will ensure all 360 deg. of the chain belt is inspected.

Using borescope J-51951 with mirror attachment, visually inspect the entirety of the two sides of the chain belt

that come in contact with the pulleys

. Slowly and carefully turn the left front tire one full turn in the forward rotation to view all of the chain belt.

CAUTION: If the tire is rotated in the rearward rotation, the camera lens may get caught between the chain belt and the pulley.

NOTE:

Be sure to remove the protective film from the mirror before the first use.
Clean the camera lens and mirror before each inspection. Use 90% isopropyl alcohol, and a lens swab from Lens Swab packet J-51963.
Before inspecting, make sure the camera handle's AA batteries are fresh and the LCD monitor's battery is char deg.

Route the camera cable past the primary pulley and position the camera lens behind the plastic guide. See figure below.

NOTE:

Insert the camera lens behind the pulley past the guide rail and between the chain belt and the CVT case.
Insert the lens approximately 8-9 inches, and then view the side of the chain belt that contacts the pulley.
Holding the borescope with one hand allows for turning the tire with the other hand.

If the inspection result is OK on all 360 deg. of the driver side, inspect all 360 deg. of the passenger side of the chain belt. Refer to figures below for examples of normal and excessive wear patterns.
