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
tool bit
against the indicator tip. Adjust the tool bit until the indicator has the same reading as
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.
