■ Assembly (V-05/-10)
Follow the procedure below to put together the
pump head.
1. Insert the head seal (7) first and then the cylinder
(2) into the pump head (3).
Make sure the flow paths of the cylinder lie direc-
tory beneath those of the pump head. The head
seal of the V-05 has mounting direction. Always
direct its concave side to the cylinder (2).
2. Fit the joint seals (6) into the tube joints (5) and
then screw these joints into the pump head (3) to
softly hold the cylinder.
3. First slide the cap nut (4), then the back seat and
the lip seals (8) onto the plunger (1) as far as they
will go. Softly rotate the lip seals on the plunger
when sliding them onto it. See the enlarged
photo on the left for the mounting direction of the
lip seals.
Do not bend or scratch the lip seals. Degrease
and clean the plunger with benzine or thinner
after this process.
4. Hold the plunger pin and pass the plunger (1)
through the cylinder (2), rotating it from side to
side.
5. Tighten the cap nut (4) to the pump head by a
torque in between 20 and 30kgf•cm .
6. Tighten the tube joints to the pump head by
15kgf•cm .
Do not tighten the tube joints too much, or they
deform the cylinder and prevent the rotation of
the plunger.
7. Pull out the plunger end from the pump head and
fit the plunger pin into the spherical bearing in the
drive joint ass'y (103).
Adjust the direction of the spherical bearing as
necessary. Always grease the plunger pin to keep
good lubrication performance.
8. Place the pump head onto the mounting plate
(14) and direct the pump head to 10 º position.
Fix the connection between the pump head (3)
and the mounting plate (14) with a spring washer
and the hex socket head bolt (20) via the hole
beneath the base (13).
