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

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
