4. Depress the piston(6) flush with body(1), then use compressed air and
blow air into the smaller retaining ball hole in the body(1). The retaining
balls(2) should be forced out the other, larger ball hole in the body. If they
do not come out, the connector may need to be cleaned, so the balls
move freely. Note: the balls will be replaced.
5. The piston(6) should now be free. Simply pull and remove the piston(6).
The internal spring(4) will be loose and can be removed.
6. Remove o-rings(5, 10 & 11) from the piston. Note: the o-rings will be
replaced.
7. Remove the o-ring(8) from the outside of the body. Note: the o-ring will be
replaced.
Re-Assembly:
1. Make sure all components have been cleaned and are ready for
assembly. Open the rebuild kit and identify the components.
2. Install the smallest o-rings(11) onto the piston(6).
3. Install the Teflon coated o-ring(5) into the large wider groove in the
piston(6). Make sure the o-ring is located towards the front end of the
piston. (As shown below).
4. Install o-ring(10) into the large narrower groove on piston.
5. Lubricate the two o-rings(5 & 10) on the large end of the piston(6) with
White Petroleum Jelly. Apply lubricate so as to fill the void between the o-
rings. (As shown below). Note: Do not lubricate the small o-rings(11).
6. Place the spring(4) into the piston(6) and install the assembly into the
body(1).
7. Compress the piston(6) into the body(1) until it stops. Install the small
balls(2) through the larger retaining ball hole in the body(1).
8. Install the sleeve friction o-ring(8) into groove on outside of the body(1).
