CARRIAGE LINEAR BEARING REPLACEMENT
STEP 1--
Remove the four screws of one linear bearing and slide
the linear bearing off the end of the carriage shaft.
STEP 2--
Insert a new linear bearing onto the end of the
carriage shaft with the tension adjustment screw pointing
outward. See FIG. 1.
STEP 3
--Adjust the tension screw of the linear bearing so when
you radially rotate the linear bearing around the carriage shaft
there should be no free play between the linear bearing and the
carriage shaft.
NOTE:
Tension is too tight if you feel a cogging action when you
rotate the linear bearing around the shaft. This cogging is from
the skidding of the bearing on the shaft and indicates the tension
screw is too tight. Sliding the bearing block back and forth should
be a smooth uniform motion.
ADJUSTMENTS
FIG. 1
STEP 4--
Slide linear bearing under carriage and attach with the four screws.
Repeat Steps 1 through 3 with the other two linear bearings.
STEP 5--
After all three linear bearings are secured to the carriage, check for correct bearing tension. The
bearing tension is correct when you try to lift the carriage and can feel no carriage movement. If there is
movement this means there is up and down free play. The most dependable method of checking free play
is to use a magnetic base dial indicator attached to the traverse frame weldment and a bearing testing fork
3706055. Read the vertical movement above each bearing. This movement should be within .003" [.07 mm].
See FIG 2.
In addition, there should only be approximately 3lbs [13 Newtons] of force required to pull the carriage from
side to side with the belt clamp disengaged. The grinding head assembly should have very uniform resistance
through its full range of travel.
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 SUBSTANTIALLY
SHORTER LIVES AND may DAMAGE THE SHAFT.
