Important: Do not nick or scar the sides of the bearing bores in the steps below.
6. Clamp the Bearing Extractor Tool in a vise and screw the Bearing (11) on the tool and gently tap with a soft mallet while supporting
and pulling the Cap (16) or Body (10) to free the Bearing (11). Repeat process until all ve Bearings (11) are removed. See Figure 1.
7. Inspect all parts for damage and wear. If wear on Cap (16), Cavity Plate (15) and Body (10) is excessive rebuilding the pump may
not be recommended (consult factory).
Assembly Instructions (Refer to Pages 3 & 4)
1. Clean all parts. Any foreign material clinging to the Driven Magnet (7) can be removed with masking tape.
2. Body Bearing Installation for .11 and .19 size pumps only: Use installation tool 60098-4. Body Bearings (11) should be installed to
.135/.145 below the face of the body (10). Install the cap bearings per step # 3.
3. Cap bearings (.11 – 2.3) and Body bearings (.23 to 2.3 only) use installation tool 60098-2. Press bearings into the Cap (16) and
Body (10). Bearings (11) should be .002/.005 below the face of the Cap (16) and Body (10). See Figure 2.
4. Apply a thin coat of silicone lubricant (furnished in Service Pak) to three new O-Rings (9) and install in the Cap (16) and Body (10)
O-Ring grooves. Omit silicone lubricant if it is incompatible with your pumped uid.
Note: Instructions for “slip t” Design. Install Driving Gear Assembly (12); then slip t Driven Magnet (7) on shaft (no screw
required for this design). Instructions for Magnet Clamp Screw Design. Install Driving Gear Assembly (12), Magnet Hub (8), Driven
Magnet (7), Magnet Clamp (6) and Magnet Clamp Screw (5). Hold Driven Magnet (7) to prevent rotation and tighten Magnet
Clamp Screw (5) counter-clockwise (left hand threads) to 200 in/oz torque (a rubber glove can be used to facilitate holding the
Driven Magnet (7). When performing the following assembly operations DO NOT apply forces to the Driven Magnet (7). Pushing or
pulling the Driven Magnet (7) may damage the Driving Gear Assembly (12).
5. Install two Dowel Pins (14) into Body (10) and slip the Cavity Plate (15) over the Dowel Pins (14) against the Body (10) face. The Cavity
Plate (15) will t properly in only one orientation. The Screw holes in the Body (10) and Cavity Plate (15) must align.
6. Install Driven Gear Assembly (13) with the longer shaft extension into the Body (10).
7. If pump is furnished with a Bypass, install Bypass Adjusting Screw (18) through the Bypass Nut (19) and turn clockwise until the
Bypass Adjusting Screw (18) is ush with the Bypass Nut (19). Attach Poppet Assembly Spring (20) onto Bypass Adjusting Screw (18).
8. Align Cap (16) with the Driving (12) and Driven (13) Gear Assembly shafts and Dowel Pins (14). Assemble carefully and make certain
the Poppet Assembly (20) goes fully into the Poppet hole and seats. See Figure 3.
9. Install two Cap Screws (17) in Cap (16) and torque alternately to 640 in/oz.
10. Rotate the Driven Magnet (7) by hand to check for any binding during rotation. The Driven Magnet (7) should turn freely. If there
is binding determine and remove cause.
11. Install Magnet Cup (4) and Mounting Plate (2) with six Mounting Plate Screws (1). Turn alternately until tight to 320 in/oz.
12. Assemble Pump-Head to Motor and Drive Housing with three Mounting Screws (3). Pump/Motor assembly is now complete.
Note: New parts may exhibit slight interference with mating surfaces. An initial “run-in” period may be required to allow the gears to seat.
Rebuilt pumps may initially decouple below normal dierential pressure or produce less than normal ow-rate until mating parts have fully
seated during initial period of operation.
