Electrically driven cooling fan. Thermo-
statically controlled 150 W motor.

Power transmission

‘The gearbox, with the final drive and
differential, is located under the engine and
forms an integral! part of the engine, The
power is transmitted from the clutch to the
gearbox by means of primary gears.

The front wheels are driven. The drive shaft
universal joints — the outer are of the
Rzeppa constant-velocity type — are per-
manently lubricated.

MANUAL GEARBOX

Single dry-plate clutch with flexible hub, of
Borg & Beck manufacture,

The clutch is hydraulically actuated. The
primary drive is in the form of a gear train.
Primary drive ratio: .00:1.

The gearbox is fully synchromesh and has
four forward speeds,

Reduction ratios, engine to driving wheels:

First gear 13.4031
Second gear 8.06:1
Third gear 5.4123
Fourth gear 3,89:1
Reverse 14.7031
Ratio of final drive: 3.89:1

The theoretical speed in fourth gear at

1 000 engine rev/min: 18.6 mph (30.0 km/h)
(with 165-SR 15 tires).

Oil capacity of gearbox: 3 U.S. quarts.

AUTOMATIC TRANSMISSION
Coupling in the form of a hydraulic torque
converter,

‘The reduction ratio of the torque converter
varies between 1.91:) and 1:1,

Chain transmission between the torque con-
verter and gearbox,

Ratio: 0.97:1.

The gearbox is of Borg-Warner manufacture
and has three forward gears.

Gear selector positions: P, R, N, D, 2, 1,

Ratios in the automatic transmission:

First gear 2.39:1
Second gear 14531
Third gear 1:1
Reverse 2.09:1
Final drive reduction: 3.89:

Brakes

Dual-circuit hydraulic foot brake system
with Girling vacuum serve. The servo unit
reduces the necessary pedal pressure by an
average of about 40%. The left front wheel
and right rear wheel brakes are actuated by
one brake circuit, and the diagonally
opposed pair of wheels are actuated by

the other.

Self-adjusting disc brakes all round.

The handbrake and foot brake have common
brake pads at the front,

The handbrake is mechanical,

Brake disc diameters: 11 in. front end
10.6in, rear,

Braking area:
Front wheels 222.sq.in,
Rear wheels 157 sq.in,
Total 379.sq- in,
Brake servo diameter: 9 in,

Braking power distribution: approx, 80% on.
the front wheels.

Wheels suspension, springing
Transverse wishbones at the front. Helical
springs and hydraulic telescoping shock
absorbers front and rear.

The front springs are pivot-mounted and are
lovated between the upper wishbones and the
seating in the wheel housings.

The front shock absorbers are actuated by
the lower wishbones,

All shock absorbers are double-acting.
Light, rigid rear axle guided by two forward-
facing longitudinal arms and two backward-
facing links, and a Panhard rod.

The springs and shock absorbers at the rear
are actuated by the forward-facing links.
