MAINTENANCE SECTION
19. If the Drive Sleeve (33) is being replaced, slide a new
Sleeve onto the Spindle Cap (32) until it is captured
between the two outer lipped edges.
20. Using the Collet Body Wrench (50) to hold the Arbor,
install the Spindle Cap onto the Arbor.
Assembly of the Sanding Arm
In the following step, ball bearings used in models
having 1/4” wide belts must have the bearing seal
facing outward.
1.
If the Idler Wheel Bearings (47) were removed, press
one Bearing into the Idler Wheel (45) until it is flush
with the edge of the Wheel. Invert the Wheel. Press
the remaining Bearing into the Wheel until it is flush
with the edge of the Wheel.
In the following step, one hole in the Yoke is
slightly larger than the other one. Determining
which hole is larger will enable you to use finger
pressure to insert the Shaft through that side of the
Yoke.
2.
Position the assembled Idler Wheel between the two
ears of the Yoke (42) and press the Idler Wheel Shaft
through the Yoke and assembled Idler Wheel.
3.
For 12” x 1/2” and 18” x 1/2” models, place the
Yoke Spring (43) into the hole in the end of the Clevis
(36) and position the assembled Yoke over the Spring
at the end of the Clevis. Make certain the slots in the
Yoke align with the pin hole in the Clevis. Compress
the Spring with the Yoke and press the Yoke Retain-
ing Pin (44) through the Clevis and Yoke.
For 18” x 1/4” models, place the Yoke Spring (43)
inside the end of the Yoke opposite the Idler Wheel
until it stops against the tab. Position the Clevis (36)
to slide into the Yoke making certain the Spring enters
the slot in the end of the Clevis. Make certain the slot
in the Yoke aligns with the pin hole in the Clevis.
Compress the Spring with the Yoke and press the
Yoke Retaining Pin (44) through the Clevis and Yoke.
4. For 12” x 1/2” and 18” x 1/2” models, insert one of
the Belt Plate Retaining Screws (40) through one of
the holes in the Belt Plate (39). Install one of the Belt
Plate Spacers (41) on the Screw and start the Screw
into the Clevis at the guard end. Insert the remaining
Screw into the hole in the Plate at the yoke end and
install the remaining Spacer on that Screw between
the Plate and Clevis. Tighten both Screws hand tight
with a screwdriver.
5. If the Belt Pad (38) is being replaced, peel the protec-
tive tape off the Pad and place the adhesive side of the
Pad against the side of the Clevis opposite the Belt
Plate.
6. For 12” models, using a screwdriver, attach the
Clevis to the Guard (34) with the two Clevis Mount-
ing Screws (37). Tighten the Screws between 8 and
10 in–lb. (0.9 and 1.1 Nm) torque.
For 18” models, position the Alignment Block (35A)
between the Clevis and the Guard (34) and secure it in
position by attaching the Clevis to the Guard with the
two Clevis Mounting Screws (37). Tighten the
Screws between 8 and 10 in–lb. (0.9 and 1.1 Nm)
torque.
7. Position the Guard (34) on the Angle Head (22) and
secure it by tightening the Guard Clamp Screw (35)
between 2 and 3 ft–lb (2.7 and 4.0 Nm) torque.
8. Install a new sanding belt over the Spindle Cap and
around the Idler Wheel.
9. For 18” models, align the Cover (35B) with the
Guard and slide it forward toward the Idler Wheel
until it snaps into position and stays there.
10. Operate ths Sander at low speed to determine if the
new belt is tracking properly. If the belt fails to track
properly, realign the Clevis by tightening or loosening
one or both of the Clevis Mounting Screws.
