.001"). Used pry to hold axial niovenient while checking the cou- Initial
pling-face run-out on sleeve bearing equipment.
b. Recorded Essinger alignment bar readings on pumps and drivers
rated 100 or more HP.

5. lt~stiilluti~~~t of'siwiotr mid clisclici,gi~ piping
a. Checked piping and pump flanges for parallel. and when the pipe
was pushed in place without strain the bolts fit free in the flange
holes.
b. Flange alignment is 0 satisfactory
0 unsatisfactory
c. Placed and adjusted dial indicators on the top and side of the
pump's coupling hub andlor flange. Observed the dial indicators
while the pump's suction and discharge flange bolts were being
tightened evenly to prevent piping strains on the pump.
d. Pump suction strainer is
0 installed 0 not installed.
6. Aic.ri1inr.v piphig
a. Cleaned and installed piping and plugs using thread compound.
Nole: All small piping (except water) is lo be Schedule 160.
7. Lirbrii~iiliotr (slcwv ntrd hall betoitigs)
a. Cleaned and installed bottom sight glass and snap drain on dry-
sump lubricated pumps. Adjusted lubricator assembly to oil-level
mark on bearing housing of wet-sump lubricated pumps. Used En-
mist-100 on all pumps. Teresstic-32 on turbines. (Exception: Units
with centralized pressure lubrication use Teresstic-32 throughout.)
b. Verified that vertical in-line pumps in hydrocarbon service have
thrust bearing installed at motor outboard end.
C. On dry-sump oil-mist lubricated motors, verified that bearing iden-
tification code on nameplate shows thrust-loaded bearings 1101 to be
equipped with shields (no letter "P" in code sequence). Radial
bearings are allowed one or no shield (one letter "P" or no letter
"P" in code sequence).
d. Cleaned oil-mist fittings at bearing housing, checked tubing for
cracks. and connected it to distribution block. Adjusted tubing so
that it sloped from the manifold to the oil reservoir without sagging.
to prevent oil traps. Verified that drain tubing on horizontal motors
is led to the drain rim of baseplates.
e. Observed oil mist and escaping mist from bearings. Note: If mist is
not observed. check "f" below.
f. Checked oil-mist generator for proper operation. Check:
0 Adequate oil in reservoir.
n Oil-mist pressure--20"-30" H,O.
0 Oil Temperature-9S"F- 125°F.
