HBW

TRANSMISSION

INITIAL

OPERATION

All HBW marine transmissions are test-run on a test

stand with the engine at the factory prior to delivery.

For safety reasons the fluid is drained before shipment.

Fill the gearbox with Automatic Transmission Fluid

(DEXRON

DEXTRON

Ill). The fluid level should be

up to the index mark on the dipstick. To check the fluid

level,

just

insert the dipstick, do not screw it in. Screw

the dipstick into the case after the fluid level is checked,

and tighten. Do not forget the sealing ring under the hex-

head

the dipstick. Check for leaks and change the fluid

after the first 25 hours.

TRANSMISSION

OPERATION

The neutral position

the operating lever on the control

console must coincide with the neutral position

the

actuating lever on the transmission. Shifting is initiated

by a cable or rod linkage via the actuating lever and an

actuating cam. The completion

the gear changing op-

eration is servo-automatically controlled within the gear.

Gear changing should be smooth, not too slow, and con-

tinuous (without interruption). Direct changes from for-

ward to reverse are permissible, since the multiple-disc

clutch permits gear changing at high rpm, including sud-

den reversing at top speeds in the event

danger.

WHEN

UNDER

SAIL

BEING

TOWED

Rotation

the propeller without load such as when the

boat is sailing, being towed, or anchored in a river, as

well as operation

the engine with the propeller stopped

(for charging the battery), will have no detrimental ef-

fects on the gearbox.

NOTE:

When the boat is sailing (engine stopped), the gear

lever must be in neutral position. The propeller is

idle

and can free wheel.

LOCKING

THE

PROP

Locking

the propeller shaft by an additional brake is

not required: use the gear lever position opposite your di-

rection

travel for this purpose. Never put the gear lever

in the position corresponding to the direction

travel

the boat.

CONTROL

CABLES

The gearbox is suitable for single lever remote control.

Upon loosening the retaining screw, the shift lever can be

moved to any position required for the control elements

(cable or rod linkage). Make certain that the shift lever

does not contact the shift lever cover plate: the minimum

distance between lever and cover should be O.5mm.

The control cable or rod should be arranged at a right

angle to the shift lever when in the neutral position. The

neutral position

the operating lever on the control con-

sole should coincide with the neutral position

the shift

lever on the gear box.

The shifting travel,

measured at the pivot point

the

shift lever, between the neutral position and end positions

A and B should be at least 35mm for the outer and

30mm

for the inner pivot point.

A greater amount

shift lever travel is in no way

detrimental, and is recommended. However,

the shift

lever travel is shorter, proper clutch engagement might be

impeded which, in tum, would mean premature wear, ex-

cessive heat generation and clutch plate failure. This

would be indicated by slow clutch engagement or no

engagement at all.

NOTE:

Checkfor

proper shift lever travel

least each

season.
