- Gap Inspection
(1) Remove the brake release bolt [5] and the manual release prevention spacer [4].
(2) Remove the cover [13].
(3) Insert a gap gauge between the stationary core [1] and the armature plate [17]
and measure the gap. Measure in 3 locations around the circumference.
(4) Adjustment is required if the gap value is near the limit.
(You cannot adjust the thickness of the gap adjustment shims to about 0.35 to 0.45 or less.)
- Gap Adjustment
(1) Remove the brake release bolt [5] and the manual release prevention spacer [4].
(2) Remove the cover [13].
(3) Remove the shaft-retaining C-ring [14], and remove the fan [15].
(4) Loosen the attachment bolts [8] and remove the spacers [6], gap adjustment shims [7], attachment bolts [8] and fixed plate [16] as
a set. When removing the attachment bolts [8] only, make sure not to fall the gap adjustment shims [7] and the shock absorber [22].
(5) The gap adjustment shims [7] have a thickness of 0.35 – 0.45mm. Reduce the number of shims according to the wear conditions,
then reassemble the spacers [6], gap adjustment shims [7], attachment bolts [8] and the fixed plate [16] as a set.
(6) Check the gap G, and readjust the shims if there is a large difference between the gap and the required value.
(7) Turn the power on and off to check brake action.
(8) Attach the fan [15], shaft-retaining C-ring [14] and cover [13].
(9) Finally, attach the brake release bolt [5] and the manual release prevention spacer [4].
