All of the shaft seal parts, which are included in the shaft seal kit, have now been removed. Each part should
be inspected separately if the seal is to be reused. It is recommended that this entire shaft seal be replaced
(refer to Fig. 7).
Prior to assembly, place one O-ring in the I.D. of the bronze sealing ring and one O-ring in the I.D. of the
aluminum housing. Place the six springs in the cavities in the housing. Care must be used to protect the parts
from damage by the shaft during assembly (refer to Fig. 8).
Slide the sealing ring over the shaft and onto the shaft pilot diameter with the O-ring facing the pump. Work
the ring into place using hand force only (refer to Fig. 9).

Insert the stationary seal pilot into the aluminum housing, locating the notch in the stationary seal over the pin
in the housing (refer to Fig. 10).
