2) With reference to the photo's above, place the
components on the reassembly tool in the following
order: locking-clip, tip-holder spring, seal-holder,
O-ring – take care that the spring is the correct way
up and that the fl at
surface of seals, rings
and washers faced the
spring.
3) Insert the components into the tip-holder with the
aid of the reassembly tool.
4) Push on the locking-clip until it snaps
into place.
B) Piston Assemblies
1) Lubricate the piston, as described in
the section above.
2) Gently, slip a lubricated piston into
the tip-holder, with a slight twisting
motion. Avoid using too much force
as this could dislodge the O-ring.
