BORG WARNER VELVET DRIVE TRANSMISSION
OIL COOLER
SHIPMENT
For safety reasons, the transmission is not filled with trans-
mission fluid during shipment and the selector lever is tem-
porarily attached to the actuating shaft.
Before leaving the WESTERBEKE plant, each transmission
undergoes a test run, with Dextron
III ATF transmission fluid.
The residual fluid remaining in the transmission after drain-
ing acts as a preservative and provides protection against
corrosion for at least one year
if properly stored.
TRANSMISSION FLUID
Check the transmission fluid level on the dipstick. If the
transmission has not been filled, fill with Dextron
III and
continue
to use this fluid. During the first 25 hours of opera-
tion, keep a lookout for any leakage at the bell housing, out-
put shaft and transmission cooler. This fluid should be
changed after the first 25 hours and approximately every
300
operating hours thereafter and/or at winter lay-up.
A CAUTION: Be ceffaln the transmission Is filled
and the correct slzs cooler Is properly Installed before
staffing the engine.
SHIFT LEVER POSITION
The gear shift control mechanism and linkage must position
the actuating lever on the transmission exactly
in Forward
(F), Neutral
(N), and Reverse (R) shifting positions. A detent
ball located behind the transmission lever must work freely
to center the lever in each position.
The gear shift positions at
the helm must
be coordinated with those of the Velvet Drive
actuating lever through shift mechanism adjustments. An
improperly adjusted shift mechanism can cause damage
to
the transmission. The shifting mechanism and transmission
actuating lever should be free
of dirt and well lubricated to
ensure proper operation.
Shifting Into Gear
Place the gear shift in Neutral before starting the engine.
Shifting from one selector position to another selector posi-
tion may be made at any time below
1000 rpm and in any
order.
Shifts should be made at the lowest practical engine
speed.
Start the engine and set the throttle at idle speed;
allow the transmission fluid to warm up for a few minutes.
Neutral
Move the gear shift lever to the middle position. You should
feel the detent. This centers the actuating lever on the trans-
mission. With the control in this position, hydraulic power is
completely interrupted and the output shaft
of the transmis-
sion does not tum.
NOTE: Some transmissions are equipped with a neutral safety
switch.
Unless the transmission actuating lever is perfectly
aligned in neutral, the engine starter will not activate.
Forward
Move the gear shift lever to the forward position. You should
feel the detent.
The actuating lever on the transmission is in
the forward position. The output shaft and the propeller shaft
move the boat in a forward direction.
Reverse
Move the gear shift lever to the reverse position. You should
feel the detent.
The actuating lever on the transmission is in
the reverse position. The output shaft and the propeller
should move the boat
in a reverse direction (astern).
NOTE: Moving the transmission actuating lever from Neutral
Position to Forward is always toward the engine. Reverse is
always away from the engine.
If boat moves backwards with
the gear shift control in the forward position, shut
off the
engine! This problem
may be a result of incorrect movement
of the actuating lever by the gear shift lever.
