Adjusting Carriage Bearings
ff the carriage bearings are loose it not only
allows the saw blade to move up, down, and
sideways but also results in inaccurate cuts.
Before following these steps make sure the
tracks (steel rods) and carriage bearings have
been cleaned by wiping them with a clean
cloth.
When properly adjusted, the top and bottom
face of all four bearing grooves should be in
contact with the arm tracks for their entire
length and carriage should roll smoothly
with some resistance.
To test for looseness between bearings and
tracks on radial arm, perform the following
steps.
1. Remove left-hand carriage cover. (2
screws)
2. Push the carriage to its full rearward posi-
tion.
3. Grasp front carriage bearing as shown and
hold as tight as possible. At the same time
pull carriage forward. If you can stop the
bearing from turning, it requires adjusting.
4. Check rear bearing in the same manner.
5. Adjust as follows:
a. Use two 1/2" wrenches to loosen nut
just enough to permit the eccentric screw
to turn.
b. Rotate the eccentric screw a partial turn
Oefl or right) as required to take up loose-
ness.
c. Hold the head of eccentric screw in the
position established in the preceding step
and tighten nut on underside of carriage.
Correct adjustment exists when you can-
not keep the bearings from turning.
However, excessive bearing pressure will
cause difficult operation and rapid wear.
