2.7 SEAL SHIMMING
For proper bearing and seal location, dimension “B” (as shown in figure 2.7.3) must be
controlled. Use the shimming bar (P/N 060580635) and a depth micrometer to measure the
bearing and seal location. This measurement is then subtracted from the number stamped on
the measuring bar. This will give you dimension “B”. Refer to shim chart to find the box in
which the value “B” falls. (The shim chart is based on shims .015” thick, actual thickness may
vary).
WARNING: Before lifting the pump into the vertical position first remove the lifting eye and
install swivel hoist. When tightening the swivel hoist ring, torque to 100ft-lbs. Once the pump
is re-assembled and in the horizontal position remove the swivel hoist and re-install the lifting
eye. Reference APPENDIX A Drawing.
With the pump securely held in a vertical position with the wet end facing up, the manifold (36),
pick-up tube (1), and seal mating ring (78) have been removed per Section 3.1.
Remove or add shims (38) as required to obtain the correct seal height. When removing or
adding shims, the fan end of the motor will have to be disassembled following the steps in
Section 4.1.
