OlJTLlNE OF CONSTRUCTION
The fuel and emission control systems of the New 3.23 BP SOHC-engine equipped 4WD model are basically
the same as those of the New 323 8P DOHC-engine equipped 2WD model, however, the fuel tank is designed
with separate right
and left sections due to the installation of the propeller shaft for the 4-wheel-drive system
and
a transfer pump is equipped to pump the fuel from the left to the right (fuei pump side) section of the
fue! tank. The following chart shows the differences between the major parts of the BP DO% 2WD model
and the BP SOHC 4WD model.

OUTLINE OF CONSTRUCTION
A hydraulic clutch control mechanism is used.
The basic construction is the same as that of 323 2WD model, but there is no interchangeability of parts
except for the release cylinder.
1. An assist/return spring is used on the BP DOHC Turbo model to reduce the required clutch pedal effort..
2. The hydraulic clutch master cylinder for the 8P DOl-lC Turbo model has a built-in check valve.
3. To improve clutch operation feeling and increased parts life, a friction plate and needle roller bearings
are used between the release fork and the release bearing.
