When it is necessary to replace or reinstall holder mounts, complete the steps in these sections:
-
Use a 5/32 in Allen wrench or T27IP torx+ key to remove the 1/4-28 button head cap screws (A) and NL6 Nordlock washers (B).
-
Remove the holder mount (C).
This section explains how to install the holder mounts using the height setter. The height setter verifies that the holder mount and the brush holders are at the correct distance from the collector ring.
-
While holding the trigger (A) in its disengaged position, slide the height setter (B) onto the holder mount (C) until the guide boss (D) is bottomed out in the guide slot (E).
-
With the height setter positioned all the way down, release the trigger (A) and allow it to move to the engaged position (F).
-
Ensure the height setter with holder mount (B) is on the mount side of the adapter (G). Place the height setter with holder mount against one of the adapters on the yoke (H). Position so that the height setter rests against the collector ring (I) until both height setter ribs (J) contact the collector ring.
The adapter may need a rotational adjustment. To maximize ring coverage, use the alternate mounting positions on the adapters as needed.
-
Using a 5/32 in Allen wrench, fasten the 1/4-28 button head cap screws (K) and NL6 Nordlock washers (L) to 110-120 in lbs (12-13.5 Nm) of torque.
-
Pull the trigger back to the disengaged position.
-
Remove the height setter.
