Disassembly Instructions Provide a clean surface for work area. Separate the pumphead from the magnet cap. Remove the 3 screws      and disassemble front housing     , driven gear     , central housing      and dowel pins     . If the pump is equipped with by-pass, make sure not to damage the sealing poppet      . Remove the poppet assembly from the adjusting screw (fig. 5), remove the by-pass nut     , the adjusting screw     turning counter-clockwise, the by-pass washer      and the by pass seal      from the cap. Remove the screws      which secure the magnet cup     and the mounting plate      to the rear housing      and disassemble. Remove and discard all the bushings      from the rear housing      and the front housing      with the bushing extractor tool P/N 60211 (fig.1). Remove seal      and flat seals      from the rear housing and from the front housing and discard them. If wear on front housing, rear housing or center housing is excessive, rebuilding the pump my not be advisable.

Re-Assembly Instructions Clean carefully all parts before re-assembling. Any foreign body material clinging to magnet must be removed.

Note Bushings - Bushings on both sides of gears must be recessed 0.5 mm from the face of the rear housing and front housing      (fig. 2) Bushings Installation - Press 6 new bushings      into the rear housing      and front housing      as shown in figure 2 using P/N 60212 installation tool. Once in place, the bushings need to be reamed with P/N 60210 reamer tool (fig. 3). Seals - Apply a thin coat of silicone grease on the central housing      surfaces and place the flat seals      on each side of it insert the driving gear      into the rear housing and then insert the shaft of the driving gear in the driven magnet using the spacer P/N 60213 (fig. 4). Insert 2 dowel pins      in the body. Slip carefully central housing      onto dowel pins against body face, verifying the proper, alignment of the screw holes. Install the driven gear      (The side of gear assembly with longer shaft extension goes into the rear housing). If pump is equipped with by-pass, install the by-pass

seal      , then by-pass nut      and tighten to prevent by-pass seal rotation. Then tap the by-pass seal with the P/N 60214 tool (fig. 6). Disassemble the by-pass nut and install by-pass washer and turn clockwise the adjusting screw      before installing again the by-pass nut tightening. Align the cap bushing holes with gear shafts, and dowel pins      with cap dowel pin holes and assemble. Make sure that the poppet assy goes fully into poppet holes and seat (fig. 5). Install 3 screws      in cap      and tighten alternately as tight as possible. Turn driven magnet with fingers to check for any binding during the rotation: the magnet should turn freely. Install magnet cup      and mounting plate      with 3 screws      and turn alternately until tight. Assemble the driving magnet to the motor (see fig. 7) and the pumphead to the motor.
