Removal
Release and remove the retaining screws (F) securing the end plate / adaptor (A). Slide off the
segments (B) and spacers (C) from the central core, or single Plastic Disposable Stock (H). Note : On
earlier machines the driving pin (E) on the inner diameter of the segments must be aligned with a slot
(D) on the core (G) where the two parts join.
Refitting
First slide on a segment then alternately a spacer and a segment. Sufficient spacers and segments
must be fitted to allow the end plate to nearly abut with the core and also clamp them tightly. The peg
(E) on the segment (B) to be alternatively located round the core clock face at 12, 2, 4 o’clock and so
on until the core is filled, failure to observe this could cause the brush to bounce. The last segment must
have the pin (E) on the segment (B) located in the cutout (D) to ensure the peg does not interfere when
the parts are bolted together.
Lightly smear the retaining screws (F) with grease.
This assembly is designed to accommodate 406mm diameter segments.
NOTICE: The plastic disposable stock can be recycled.
