Maintenance
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).
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. Use a soft blow mallet
to gently tap the sleeve along the shaft if necessary.
