- Gap Inspection
(1) Remove the cover [11].
(2) Loosen the fan set screw [20] and remove the fan [6].
(3) Remove the waterproof seal [14].
(4) Insert a gap gauge between the stationary core [17] and the armature plate [1]
and measure the gap. Measure in 3 locations around the circumference.
(5) Adjustment is required if the gap value is near the limit.
- Gap Adjustment
(1) Remove the cover [11].
(2) Loosen the fan set screw [20] and remove the fan [6].
(3) Remove the waterproof seal [14].
(4) Pull off the V-ring [7].
(5) Remove the waterproof cover attachment bolts [13], and remove the waterproof cover [12].
(6) Slightly loosen the attachment bolts [4] and rotate the fixed plate [5] counter clockwise, as far as it will go. Then
tighten the attachment bolts [4]. After tightening, measure the gap (G) and check to see if the gap value is be-
tween the required value and the limit. (This operation will reduce the gap by 0.3 mm.)
(7) Attach the waterproof cover [12] by using the attachment bolts [13]. Attach the waterproof cover [12] so that the
gap (A) between its hole and the motor shaft [19] is nearly uniform around the circumference.
(8) Clean the surface of the waterproof seal [14] to remove impurities.
(9) As shown in the construction diagram, install the waterproof seal [14] between the stationary core [17] and the
waterproof cover [12]. Insert the waterproof seal [14] with its arrow mark pointing toward the load side. Align the hole in the water-
proof seal [14] for the release bolt with the position of release bolt. Attach the waterproof seal [14] so that its protrusion fits snugly
around the entire circumference of the stationary core’s groove [17]. Otherwise water could leak in.
(10) Turn the power on and off to check brake action.
(11) Attach the V-ring [7]. Wipe off the lip and surface near the lip of the V-ring [7], lightly coat the lip surface with grease and attach.
Observe the attaching dimension (B = 4.5mm).
(12) Attach the fan [7] and cover [11]. Use a fan set screw [20] coated with Three Bond TB2365 (Sumitomo part number EW444WW-01),
and tighten with a torque of 0.3 – 0.5 N•m.
Note: If the optional brake release bolt is installed, disassemble the brake after removing the release bolt.
