ROTATING ELEMENT-XLTP FRAME
(a) Install outboard bearing (112) on shaft.
(b) Install bearing lock washer (382) on shaft. Place tang of lock washer in shaft keyway. Thread locknut
(136) onto shaft. Tighten nut until snug and bend tang of lock washer (382) over flat on nut.
If it is
necessary to adjust the position of the locknut so that the tang will lineup with the flat, always
tighten the nut, never loosen it.
(c) Lightly lubricate bearings with oil and coat the outside of outboard bearing (112) and bearing hous-
ing bore (134). Slide bearing housing (134) onto shaft and over outboard bearing. DO NOT FORCE.
(d) Install gasket (360C), bearing cover (109C) and bolts. Check to see that shaft turns freely. Refer to
Appendix, page 42, for bolt torque values.
(e) Install inboard bearing (168A). If bearing is greaseable type, install with shield away from impeller.
Lightly lubricate bearing with oil or grease as required.
(f) Install new 0-ring for bearing housing (496). Lubricate outside of bearing housing and inside
diameter of frame bearing bore (228) with oil.
(g) In.stall shaft and bearing assembly into frame (228). Rotate shaft to see that if it turns freely.
(h) Install bearing cover bolts (370C), hand tighten only. Install jack bolts (370D) with lock nuts (423),
hand tighten only.
(i) Install bearing frame foot (241), hand tighten bolts (370F).
POWER FRAME CHECKS AND LIQUID END ASSEMBLY-ALL MODELS
(a) Place power frame in the horizontal position, support frame assembly so that it does not tip over.
Check shaft end play by moving shaft forward and backward by hand. Dial indicator movement
should be within tolerances listed in Appendix.
If values are greater, disassemble power end for in-
spection. See troubleshooting, page 33.
(b)
Install shaft sleeve (126). Install impeller, (101) on shaft (122). Rotate shaft one full revolution, and
check for shaft/sleeve run out. See tolerances listed in Appendix. Maximum allowable indicator
runout is 0.002 inch. If values are greater, disassemble power end for inspection. See troubleshooting,
page 33.
(c) Attach dial indictor to shaft, place indicator against face of frame. Rotate shaft by hand so that
indicator sweeps the entire fit for 360 degrees. Maximum indicator runout should be no more than
0.005 inch.
If greater, disassemble and determine cause.
(d) Lightly lubricate adapter 0-ring (360D) and install in frame face. Install frame adapter (108) with
bearing isolator seal (333A, MTP frame only) onto the power end assembly, align bolt holes and
dowel pin holes. Install dowel pins (469B) and frame to adapter bolts (370B). See Appendix for bolt
torques. Tighten evenly in a crisscross manner.
(e) Attach dial indicator to shaft, place indicator against mating face of adapter. Rotate shaft 360 degrees.
Total indicator runout should not exceed 0.005. With dial indicator still attached to shaft, position
indicator on inside diameter of mating face. Rotate shaft again a full 360 degrees. Total indicator
runout should not exceed 0.005 inch.
If greater values are measured, disassemble and determine
cause be- fore proceeding with assembly.
