CARRIAGE LINEAR BEARING ADJUSTMENT & REPLACEMENT
CARRIAGE LINEAR BEARING REPLACEMENT
STEP 1- Loosen & remove the limit switch bracket
(item 17, fig. 3) and place it as the electrical lead will
allow. Unplug the electrical lead from the motor and
place it to one side.
On the 3096 model only, release
all spring tension by
removing the horizontal adjusting screw assembly. On
the 3096 model only, remove the rubber boots from
both sides of the carriage on the front shaft. (see fig.
5)
Remove pin driver (item 2, fig. 3) from linear actuator
(item 29, fig. 3). Then remove the screws (item 33, fig.
6) from the front and rear carriage shafts. Then slide
the carriage assembly to the right end of the carriage
shafts (fig. 6) Lift eh carriage assembly and carriage
shafts (fig. 6), slide the carriage assembly to the right
off first the rear carriage shaft and ten off the front
shaft. The shafts must be gripped by hand and pulled
left while the carriage assembly is moved right. After
removing the carriage assembly, lay it on its side on
the floor.
STEP 2- Remove the 3 linear bearing pillow blocks
(item 12, fig. 6) and discard.
STEP 3- Insert the three new linear bearing pillow
blocks (item 12, fig. 6). Adjust the tension screw on
the side of each bearing block so when you radially
rotate the pillow block around the carriage shaft there
should be no free play between bearing (item 12, fig.
6) and carriage shaft (item 42, fig. 6). Repeat this
adjustment to all three pillow blocks and then remove
the pillow blocks from the carriage shaft.
NOTE: Tension is too tight if you feel a cogging action
when you rotate pillow block around the shaft. This
cogging is from the skidding of the bearing on the shaft
and indicates tension screw is too tight. As a final
check, sliding the bearing back and forth on the shaft
should be a smooth uniform motion.
The carriage assembly weighs
approximately 40 lbs. Be prepared to
handle the weight or get assistance in
handeling.
Setting the bearing tension correctly is
critical to proper grinding. Bearings which
are too tight or too loose will cause poor
grind quality. Also, bearings which are too
tight will have a substantially shortened life
and will damage the shaft
