3.10 SEAL INSTALLATION
3.10.1. 2-7/8” Single Seal (Only)
3.10.1.1 Lubricate and install seal mating ring o-ring in the hub of the rotor cover (4).
Align the drive pin with the hole in the mating ring and insert the seal mating ring
(78) into place. The seal mating ring should move back and forth slightly within
the drive-pin hole. *NOTE: IF YOU ARE ONLY INSTALLING A PICK-UP TUBE
OR SEAL, STEPS 3.10.1.2 – 3.10.1.4 & 3.10.1.6 ARE NOT REQUIRED.
3.10.1.2 For proper bearing and seal location, dimension “B” (as shown in Section 2.8)
must be controlled. Use the shimming bar (P/N 060580635) and a depth
micrometer to measure the seal height.
The seal height measurement is then subtracted from the number stamped on
the measuring bar. This will give you dimension “B”. Referring to the shim chart
(Section 2.7) find the box in which the measured value “B” falls. (The shimming
chart is based on shims .015” thick, actual thickness may vary).
3.10.1.3 Now tilt the pump from its vertical position to a horizontal position. Remove the
four socket head cap screws (60) and bearing cap (14). Install the correct
number of shims (38). Reinstall the bearing cap and four cap screws (60) and
torque to 35 ft. lbs. Return the pump to a vertical position.
3.10.1.4 Again measure dimension “B” to be certain it is now correct.
3.10.1.5 Place a dial indicator (P/N 060095053) on the seal face of the seal mating ring
(78) and rotate the assembly by hand 360 degrees. The runout of the face must
be within .001: (0.025mm) T.I.R.
3.10.1.6 Install alignment tools (P/N 0661975) in rotor case for endbell/rotor
case/pedestal alignment. Align endbell so that the Roto-Jet name is at the top.
Carefully slide the endbell (26) into place. Lubricate and install the twelve
endbell socket head cap screws (63) and torque to 54 ft. lbs.
3.10.1.7 Lubricate the seal o-ring (44). By hand, carefully press the mechanical seal (75)
into position in the manifold (36). Care should be taken not to scratch or chip the
seal face during installation.
NOTE: The seal installation instructions (Section 4.5) are for a stationary seal
arrangement. For a rotating seal, simply reverse the mating ring and seal.
Mating ring (78) in the manifold and the seal (75) in the rotor cover.
3.10.2. 3-1/2” Single/Double Seal
3.10.2.1 Apply O-ring lube to new O-ring (44) and install in seal plate (70).
3.10.2.2 Apply light oil to seal cavity.
3.10.2.3 Install and seat seal (75) in seal plate (701). Caution to be taken to avoid
chipping seal face.
