Step 2 - Replacement of the outer piston

(1) Using two spanners,
carefully undo the lower
piston nut. Discard the
piston but retain the nut.

(2) Remove the new piston
from retainer and fit to the
shaft curved end face up
(see picture). Replace the
front nut using a small drop
of Loctite 262 on thread.
Tighten the nut only until
the piston can no longer be
rotated by hand.

(3) Holding the end cap (A)
in one hand, pull the outer
pump handle (B) until the
piston is fully withdrawn
inside the end cap.

Step 3 - Returning plungers into cylinders

(1) After lightly oiling the
top inside edge of the
cylinder, position the plunger
assembly on the cylinder
with one hand. With the
palm of the other hand,
firmly push the plunger
down fully.

(2) Remove the new piston
from retainer and fit to the
shaft curved end first.
Replace the front nut using a
small drop of Loctite 262 on
thread. Tighten the nut only
until the piston can no
longer be rotated by hand.

(3) Remove the sleeve from
the inner piston and discard.
Lightly oil the inside edge of
the hollow outer piston shaft
and then gently ease the
piston inside. Refit the
gauges.
