ADJUSTING

CARRIAGE

BEARINGS

In

proper

adjustment the top

and bottom

radii

of all

four

bearings should

be

in

contact with the

arm tracks for their

entire

length and

carriage should roll freely

but 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. Push

the carriage to its full

most rearward

position.

3. Finger hold

front

carriage bearing

as

shown

and apply

as

much

force

as

possible

and at the

same time

pull

carriage

forward.

lf

you

can stop

the bearing from

turning it will

require

adjusting.

4.

Check rear

bearing

in the

same manner

and adjust

as

follows:

a.

Loosen

nuts

just

enough to

permit

the

eccentric

screws

to turn.

b. Rotate the

eccentric screws a

oartial

turn

(left

or

right)

as required

to

take

up

looseness.

Hold

the

heads

of

eccentric screws

in

the

position

established in the

preceding

step and tighten nuts

on underside of carriage.

Correct adjustment exists

when

you

cannot

keep the bearings from

turning.

However, excessive

bearing

pressure

will

cause

difficult

operation and rapid

wear.
