cant wear or loose bearing fits. Also, check all nuts, bolts,
retaining rings, etc., to be sure that they are tight and
secure. Grease all of the gears on the inside of
the winch base and apply a drop of oil on all of the bear-
ings in the clutch mechanism and place a drop of
oil on the roller clutch. Do not over lubricate these
areas and do not use grease in the roller clutch. The
clutch mechanism and the brake pads and brake disc
on the TW9000 & TW9015 must be kept clean and oil free.
ADDITIONAL MAINTENANCE TW9000 & TW9015
3. Check the operation of the roller clutch in the brake
disc assembly (AF). Carefully rotate the brake disc
and observe the motor shaft. When the disc is turned
clockwise the motor shaft should turn with it. When
the disc is turned counterclockwise the motor shaft
should not turn.
4. If the clutch has been slipping and requires adjust-
ment the following procedures should be used. The
clutch is adjustable in ten degree increments. With a
screwdriver and pliers, remove the end of the clutch
spring from the hole in the winch base. The spring
tension is quite high so be careful to maintain a firm
grip on the spring. The O-ring should be rotated so
that the cut out portions align with the lugs on the
spring keeper. (See FIG. 3)
The ring can then be expanded with a pencil or similar
object and the spring keeper can be lifted free from
the clutch nut. Rotate the keeper clockwise 10
degrees and install on the next serration in the clutch
nut. Reinstall O-ring and rotate slightly so that the cut
outs are not in line with the lugs on the spring keeper
and reinstall the clutch spring into the hole in the
base. Adjustment of the clutch more than 10 degrees
to 20 degrees should normally not be necessary. With
only spring pressure (do not forcibly tighten the clutch
mechanism) the spring lug on the spring keeper
should come to rest at approximately the 2:30 o’clock
position. (See FIG. 4)
