with the indicator tip on the diameter size of the bore to be cut. See Table 3-5. Adjust the dial
indicator.

Install the tool bit into the boring bar. Do not completely tighten the setscrew. Install the tool
bit adjusting knob into the boring bar. Hold the setting block and indicator against the boring
bar so the indicator tip will be over the tool bit. Turn the adjusting knob clockwise to push the

when adjusted on the setting standard. After the tool bit is correctly adjusted, tighten the
setscrew and remove the adjusting knob.

touch the bushing in the pump body.
