NOTES:<br />
• Some adapters use a bolted retaining plate (15)<br />
and others use a snap ring (16) and spring<br />
retainer (17).<br />
• The O-ring (14) fits into a groove machined into<br />
either the head (11) face or adapter (7) base.<br />

head join at each socket head bolt location. Loosen the socket head bolts evenly and incrementally<br />
to release any potentially high-pressure gas. Do not breathe gas emission from VVCP.<br />
7. Remove socket head bolts and turn the adapter counterclockwise to thread it off of the piston<br />
stem. Place adapter base up next to the head.<br />
8. Remove the piston stem and piston assembly from the head. The piston stem and piston are permanently<br />
joined; do not attempt to disassemble them.<br />
9. Remove the piston ring from the piston.<br />
10. Depending on VVCP size, <strong>Ariel</strong> machines a groove for the O-ring into either the face of the head<br />
or the base of the adapter. Remove and discard the O-ring.<br />
11. Some adapters use a bolted retaining plate while others use a snap ring and spring retainer:<br />
