6.4.6 Wet end assembly instructions
The following steps are used to assemble the wet end in sequential fashion for the XHD Value Option
model, as well as the XHD model when the complete wet end connection option is not employed.
6.4.6.1 Install the knock-off ring
1.
Coat the shaft (122) protuberance with an anti-seize compound.
2.
Loosen but do not remove the hex head screws holding the knock-off ring assembly (149) halves
together.
3.
Position the knock-off ring onto the shaft (122) and make sure that the part is properly oriented. The
side of the knock-off ring that should face the impeller is marked "THIS SIDE OUT".
4.
Slide the knock-off ring towards the bearing cartridge housing until it is flush with the inboard end
cover (119). Be sure to assemble the knock-off ring (149) such that the words "this side out" can be
read from the threaded end of the shaft.

On the XHD model, the knock-off ring will fit over the inboard Inpro seal (332A).
6.4.6.2 Install the shaft sleeve
1.
Prepare the shaft sleeve (126) by coating the shaft sleeve o-ring (412F) and impeller hub o-ring
(412A) with a lubricant and installing the o-rings into the sleeve.
2.
Slide the shaft sleeve (126) with the impeller hub o-ring (412A) properly positioned (facing outward)
onto the shaft. Use care positioning the sleeve on the shaft to avoid any o-ring damage.
3.
Continue sliding the sleeve until it is fully seated in the knock-off ring. (Sleeve to Impeller Oring
(412A) is not required with Rubber lined components.) Use a soft blow mallet to gently tap the
sleeve along the shaft if necessary.
