or damaged. Install on plunger rod and press
into crankcase with tabs out. (Figure A)
2. Place inlet manifold on work surface with
small I.D. ports up. (Figure B)
3. Lubricate new low
pressure seal and
press into position
in the manifold
chambers with
garter spring
down. (Figure B)
4. Carefully examine plungers for scoring or
cracks and replace if worn. Next lubricate ce-
ramic plungers and new high pressure seals.
Place the
deeper
recessed
hole of the
plunger into
the metal back side of the seal and slide
seal to the middle of the plunger. (Figure C)
5. Place inlet manifold on work surface with
larger I.D. ports up. Install plungers with
seals into ports
with metal seal
side into mani-
fold.
Press into posi-
