11. Maintenance
Using circlip pliers, remove the circlip positioned on the left of the spindle on
the outside of the headstock as shown in
Fig
11.11
.
The spindle is held in place by 2 bearings, one can be seen on the outside left
of the headstock as shown in
Fig
11.11
and the second is on the inside right
of the headstock. Carefully knock the spindle from the headstock using either
a soft head mallet or a hammer against a block of wood towards the tailstock
as shown in
Fig.
11.12
. Once free from the bearings, the spindle can be
removed as shown in
Fig
11.13
. Hold the spindle pulley while removing the
spindle to avoid it dropping into the headstock.
Before fitting the new belt re-install the speed sensor, positioning as shown
in
Fig
11.14
and screw back in place. The vertical sections of the sensor must
be on either side of the sensor plate as shown.
The new belt can now be placed over the spindle pulley as shown in
Fig
11.15
before replacing the spindle to its original position and re-installing
the pulley blind set screws, circlip and handwheel.
