Daktronics Scoreboard Dual Hoist - Manual (Page 18)

14 System Maintenance
To adjust the brake, loosen the locknut on the gearbox shaft until the Bronze Bearing and the
Belleville Washer spin with a small amount of finger pressure.
Run the hoist DOWN approximately two feet so that the secondary brake is engaged and then
tighten the locknut to 70 inch/pounds with a torque wrench. Run the hoist down and check
for noise. If there is still noise, tighten the nut 1/8 of a turn and then run the hoist down again.
Repeat until the noise has ceased.
Do not tighten the nut to where there is no more adjustment available .
Check brake pad wear
The brake pads should be checked for wear on
a routine basis. The pads may wear unevenly
so both sides need to be checked. Measure
the distance between the brake disc and
the ratchet wheel (both sides). The distance
(space) should be greater than .065". If .065"
or less the brake pads need replacement at the
factory.
After making the adjustment and checking the
Brake Pads, re-install the cover making sure to
fit the cover into the slots on the backbone.
