-POWER STEERING GEAR BOX CONSTRUCTIONRlsJLIIUB,
ne steering gear box is of the rack and pinion type
with a built-in hydraulic control unit which uses a
compact and highly reliable rotary valve.The steering gear box, in the same way as the
manual steering gear box, is installed to the body by
way of the mounting rubber in order to reduce the
transmission of vibrations.

MANUAL TRANSAXLE <2WD> - Transaxle Control
21-5
IANSAXLE CONTROLFor transaxle control, a floor-shift system employing
cables for control has been adopted.
0Rubber vibration-absorbers have been provided
at the points of connection of the shift and
select cables to the transaxle and the body in
order to prevent the transmission of minor
vibrations to the body.l A vibration-absorbing steel plate has been
pro-vided at the shift lever bracket’s cable connec-
tion point in order to reduce the shifting noise.
l Shaking movement of the shift lever during
acceleration and deceleration has been attenu-
ated by the flexibility of the shift and select
cables.

Hump mode2210llrHump phenomenon specific to viscous couplings
Hump is a phenomenon specific to viscous couplings
althob,, Iit does not occur under normal operating conditions.
This phenomenon occurs when the silicone oil temperature has
risen due to sustained differential action. Normally silicone oil
fills the space between the inner and outer plates, preventing
their direct coupling. When silicone oil expands at a high
temperature to such a degree as to develop abnormally high
pressure between the plates (normal thermal expansion is
absorbed by compression of air mixed in silicone oil), silicone oilescapes from between the plates. As a result, the plates
couple directly, causing abrupt torque transmission. When the
viscous coupling is directly coupled in this way, a rotating
speed difference does not exist, and then silicone oil tempera-
ture drops and normal function is restored.

TRANSAXLE
GENERAL INFQRMATIONRzlBBACF4A22 automatic transaxles with different shift pattern are introduced to match engine output characteristics.
These F4A22 automatic transaxles are transaxles of KM1 70 Type II series and each is a two-mode
electronically controlled automatic transaxle with shift patterns of two modes.
