NOTE
The six 1/4-28 hex head cap screws loosen the tapered lock
nut.
14. Precisely align the boring bar:
a) Position a dial indicator to check concentricity
between the boring bar and the bore.
b) Adjust the screws in the centering blocks until the
bar is centered.
ID-mount bearing support assembly setup
Though the ID-mount bearing support assembly mounts inside the work piece, it can be placed
anywhere along the boring bar.
CAUTION
Bearings placed too far apart allow the bar to deflect,
reducing bore accuracy.
1. Clean the bore with solvent to remove grease, oil, and dirt.
2. Examine the bar for nicks or cuts. Dress it smooth if necessary. A bar with
nicks or gouges can damage mating parts (including the tool carrier assembly
and rotational drive unit) beyond repair. Clean the bar with solvent to remove
dirt and chips.
CAUTION
The boring bar is not hardened. To prevent damage to the
bar, do not strike it against the bearing supports or the work
piece.
3. Measure the diameter of the bore into which the bearing will fit. Using Table 1
on page 20, select the components required.
4. Position one bearing support assembly on the bar. Tighten the lock nut using
the impact spanner wrench in the tool kit.
5. Slide the bar and bearing into the work piece.
6. Using a dial indicator and the jaw crankshafts, center the bar in the work
piece. Turn the crankshafts until the jaws are tight in the bore. Do not exceed
22 ft-lbs (30 Nm) of torque.
