• Check for oil leakage on the welded or gland packing portions.
• Check the shock absorber piston r od for cracks, deformation, or other damage and replace if necessary.
SUSPENSION ARMS
• Check the suspension arm for damage, cracks, deformation and replace if necessary.
• Check the rubber bushings for damage, cracks and defo rmation. Replace suspension arm if necessary.
• After installing the radius rod, check the wheel alignment and adjust if necessary. Refer to RSU-17, "Wheel
Alignment (Unladen*)".

< SYSTEM DESCRIPTION >[CVT: RE0F10D]
STRUCTURE AND OPERATION
The groove width changes according to wrapping radius of
steel belt and pulley from low status to overdrive
status continuously with non-step. It is controlled wit h the oil pressures of primary pulley and secondary pulley.
Steel Belt
It is composed of multiple steel plates (A) and two steel rings (B)
stacked to a several number. The feature of this steel belt transmits
power with compression of the steel plate in contrast with transmis-
sion of power in pulling with a rubber belt. Friction force is required
with the pulley slope to transmit power from the steel plate. The force
is generated with the following mechanism:
Oil pressure applies to the secondary pulley to nip the plate. ⇒The
plate is pushed and extended outward. ⇒The steel ring shows with-
stands. ⇒Pulling force is generated on the steel ring. ⇒The plate of
the primary pulley is nipped between the pulley. ⇒Friction force is
generated between the steel belt and the pulley.
Therefore, responsibilities are divi ded by the steel plate that trans-
mits the power with compression and the steel ring that main tains necessary friction force. In this way, the
tension of the steel ring is distributed on the entire su rface and stress variation is limited, resulting in good
durability.
Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.
