ADJUSTING
BALL
BEARINGS
AGAINST
TRACK
The cutting-head
(C)Fig.
61, is suspended
from four
pre-loaded,
lubricated,
shielded
ball bearings, two of
which are on fixed shafts at (A), and two on adjustable
shafts at (B). NOTE: CUTTING-HEAD
(C} FIG. 61, IS
REMOVED FROM TRACK ARM FOR ILLUSTRATION
PURPOSES ONLY. DO NOT REMOVE CUTTING-HEAD
FROM TRACK ARM!
After extended use, wear may develop in the track arm,
causing "play" between the ball bearings and the track.
The ball bearings must ride smoothly and evenly in the
channels
of the track
arm. Adjustment
to the two
bearings on adjustable shafts can be made as follows:
1. _
DISCONNECT
MACHINE
FROM POWER
SOURCE.
2.
Remove plastic
plug (D)Fig.
62, from the top of
track arm (E).
3.
Slide cutting-head
(C) Fig. 63, until one of the ad-
justable bearings (B) Fig. 60, is visible through hole (G)
Figs. 62 and 63.
4.
Using a 1/2" socket, extension, and ratchet (H) Fig.
63, through hole (G) in track arm, slightly loosen hex nut
on adjustable shaft (B) Fig. 61, approximately
1/8 turn.
Repeat procedure for other bearing.
