by sliding the rotary unit axially upwards along
the pump shaft. Inspect the pump shaft for any
burns or debris. Any burrs should be around
smooth with (fine grit) emery paper. See step 7 in
Figure 5.
8. Lubricate the o-ring located in the ID of the rotary
unit of the mechanical seal with a lubricant com-
patible with the seal elastomers. Carefully slide
the rotary unit of the mechanical seal down the
shaft. Rotate the seal to locate the pin on the bot-
tom of the seal with the holes in the shaft sleeve.
