Replace the valve stem and spring in the valve
body. Using the blunt end of the core key tool
APTP29, compress the valve and spring suffi-
ciently to allow the lever, anti-friction washers
and nyloc nut to be replaced.
Do not
attempt to compress the valve and spring
using the valve seat (Item 6) as this will almost
certainly damage the rubber valve seating.

Using the special wrench APS010 to prevent
the valve from turning, unscrew the nyloc nut
(take note of how far the nut is screwed on
the valve to assist reassembly)
and remove the
lever and nylon anti-friction washers.
The valve stem is spring loaded, so cover the
QD opening and leave the ASP010 tool insert-
ed to keep these parts from escaping.
Carefully remove the APS010 tool, catching
the parts as they “spring” out the open end.
The rubber valve seating (
Item #9
) can now
be removed and replaced.
