replacement with a lubricant compatible with the seal elastomers. Carefully slide the
rotary unit of the mechanical seal down the shaft.

used to hold the O-ring on the diameter of the seal housing. Carefully reinstall the seal
housing between the pump and motor shaft and slide the seal housing down the shaft
into position. Use caution when mounting the seal housing between the pump/motor
shaft so that the seal face on the stationary seat is not damaged. Align the holes of the
seal housing with the threaded holes in the discharge head and reinstall the 3 hex cap
screws by tightening evenly. Use the values given in
Torque specification
on page 34
for the final torque.
8. Reinstall the coupling pin and locate the spacer shim provided on the shaft on the seal
housing. Reinstall the coupling halves and evenly tighten the coupling bolts and torque
them to the values given in
Torque specification
on page 34 (the final space between
the two halves should be approximately equal). Remove the spacer shim and save for
future use.
