ADJUSTING THE OIL COOLED WORM BRAKE
2. Remove clutch housing #12 and clutch
#5 from winch assembly.
Remove two keys #32 from keyways. A
screwdriver can be used, at notch, to
aid in the removal of keys. Once keys
have been
removed, drum #8 and
thrust washer #47 can be removed
from drum shaft.
3. Remove motor #36 and coupling #6 from
adapter #2 by unscrewing two capscrews
#24 with lockwasher #28.
Remove keys #13 from worm shaft.
Unscrew four capscrews #23 and remove
adapter #2 from gear housing. Replace
adapter seal #42 and gasket #30.
4. See page 12 for servicing the oil cooled
brake. Remove brake housing mounting
screws #22 and remove brake with
gasket. Replace gasket #30. Remove
worm #15 and bearings #16 from gear
housing. Use soft hammer to gently tap
input end of worm and drive worm and
bearing from gear housing. Once worm
has been removed from housing,
bearing can be pressed from end of
worm.
Check for signs of wear or damage to
worm #15 and bearing #16. Replace if
necessary.
The oil-cooled, fully adjustable, automatic brake operates in the worm housing
lubricant, all parts being submerged in oil. When the brake wears to the point that
the load begins to drift, the brake can be adjusted as follows:
1. Loosen the lock nut on the adjusting screw.
2. Tighten the brake by turning the adjusting screw clockwise. CAUTION: Only ¼
turn is usually required to adjust the brake. Over-tightening can cause
overheating, and damage to the brake parts. Tighten the lock nut after
adjustment is completed.
If the brake does not respond to adjustment then a new leaf spring and brake disc is
needed.
A torque wrench can be equipped with a special adapter to fit the input shaft (worm)
of the winch. The adapter can be made by welding a nut to the end of a piece of
tubing as shown below.
After welding the cap and nut to the tubing, slot the tubing as shown. This will allow
the special adapter to slide over the keyway and will then act as a large socket. A
torque wrench can then be used to apply the proper torque. Turn the torque wrench
so that the drum turns in the spool out direction or lowering direction. The torque
rating for the Model HDG-350 should be 9 to 15 ft. lbs. If the torque wrench does not
show the proper value as it turns, then the worm brake adjusting bolt should be
turned clockwise ¼ turn to increase the torque setting. Each time the adjusting bolt
is turned, check the torque reading. Continue this procedure until the proper torque
reading is achieved. Then tighten the lock nut.
