XLT-X & X17 - Install the impeller (101) without
the O-ring (412A) and Teflon
®
washer (428D) on
plug (458Y).
5. Put shaft wrench and coupling key on shaft.
When impeller (101) makes firm contact with
sleeve (126), raise shaft wrench
(counterclockwise, viewed from impeller end of
shaft) off bench and slam it down (clockwise,
viewed from impeller end of shaft). A few sharp
raps will tighten impeller (101) properly (Fig. 152).
6. Loosen clamp bolts (370C), and jacking bolts
(370D). Measure gap between impeller (101) and
seal chamber/stuffing box cover (184) with a
feeler gauge. When 0.030 in. clearance is
reached, tighten clamp bolts (370C), jacking bolts
(370D), and locking nuts (423) (Fig. 153)
NOTE: This approximates the impeller position
when set at 0.015 in. (.38 mm) from casing.
Final impeller adjustment must be made after
installation into casing.
