BRAKE ADJUSTMENT
FREQUENCY:
Brake adjustment should be checked daily during
heavy use or after one (1) hour of winch operation. Inspection of
brake shoes and drum for wear should be made after every ten (10)
hours of winch operation.
PROCEDURE:
To
Adjust Brakes:
1. Remove load from winch cable.
2. Remove sprocket, coupler, universal joint, or motor from input
shaft of winch.
Note:
If power source to winch requires no appreciable torque
to turn in a "Neutral" or "Off" position and an adapter
can be made to fit the coupling, this step is not necessary.
3. Using a suitable adapter, place a torque wrench on the input
shaft of the winch (47).
4. Measure torque while turning the input shaft in the
payout
di
rection. Torque settings should be as follows:
Model
Torque (lb.-ft.)
18G
50
Note:
The torque value above is necessary to brake the rated
load of the winch. In no case should the brake setting
ever be increased above this torque value.
5. To adjust the brake torque, loosen the two cap screws (23) and
rotate the cam (25}. To increase the brake setting, rotate away
from the "0" or center setting. To reduce the brake setting, ro
tate the cam back toward the "0" or center setting.
6. Recheck the torque value as indicated in 4. above.
To
Inspect or Repair Brakes:
1. Loosen and remove cap screws (23) and washers (24) from
brake assembly.
2. Gently pry the cam (25) out of the cover (28).
Caution:
Be sure to note which set of drilled and tapped holes
were used to position the cam. Failure to re-install the
cam in this position will result in the brake engaging in
the inhaul rather than the payout mode.
3. Remove the cap screws (22) from the cover (28).
4. Remove the cover (28) from the brake housing (36).
5. The brake shoes (29) may now be removed for inspection.
6. If the shoe linings are worn flush with the rivet heads, they
should be replaced.
7. Inspect the drum (33) for severe wear or scoring. If necessary,
replace the drum.
8. To remove the brake drum, remove the nut (30) and washer (31).
9. Insert two cap screws in the holes provided in the brake drum
and, using a gear puller, remove the drum.
10. Inspect the inside lower part of the brake housing for the pre-
sence of oil. If an oil leak exists, replace the seal (34).
To
Change Direction of Brake Engagement:
1. Remove cap screws (23) and washers (24).
2. Rotate cam (25) in either direction until another set of drilled
and tapped holes becomes visible through the slots in the cam.
3. Re-install the cap screws (23) and washers (24) in these tapped
holes.
4. Adjust brake as described above.
Caution:
Any change in winch mounting, direction of cable
spooling, or replacement of worm and gear may effect
the operation of the brake. If you have any question
about the performance of the brake on your Tulsa
winch, stop using it immediately and contact Tulsa
Winch, or one of our authorized distributors.
