- 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.
(Gap adjustment shim thickness is approximately 0.2 – 0.25 mm. Adjustment cannot be made at a lower value.)
- 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 xed plate [16]
as a set. When removing the attachment bolts [8] make certain not to omit the gap adjustment shims [7] or the shock absorber
[22].
(5) The gap adjustment shims [7] have a thickness of 0.2 – 0.25 mm. Reduce the number of shims according to the wear conditions,
then reassemble the spacers [6], gap adjustment shims [7], attachment bolts [8] and the xed plate [16] as a set.
(6) Check the gap G, and readjust the shims if there is a large dierence between the gap and the required value.
(7) Turn the power on and o 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].
