4. If hold down bolt holes have not been tapped in driver mount pads, you should now proceed
with task (see paragraph 2.2.4 below); otherwise, you may begin cold alignment (see
paragraph 2.2.5 below).
2.2.4 TAPPING DRIVER MOUNT PADS
Where driver mount pads have not been tapped for hold down bolts, they must be tapped before
attempting to align driver to pump. Proceed as follows:
1. Bolt dial indicator bracket to driver half-coupling or driver shaft as shown in Figure 2-8.
PUMP (OR OTHER UNIT)
HALF-COUPLING
SPACER (INSTALLED)
DRIVER (OR OTHER UNIT)
HALF-COUPLING
DIAL INDICATORS
NOTE
TO PREVENT DEFLECTION OF
INDICATORS THE BRACKETS MUST
BE RIGID IN CONSTRUCTION AND
SECURELY FIXED IN POSITION

2. Set the bracket to the horizontal (9 o'clock) position. Zero the indicator, then rotate both
shafts 180° to the 3 o'clock position; total indicator reading (TIR) in horizontal plane
(between 9 o'clock and 3 o'clock points) shall not exceed 0.002 in (0.05 mm). If TIR is
excessive:
a. hold distance between half-couplings and move driver frame to correct alignment in
horizontal plane;
b. again rotate shafts and check readings;
