DISASSEMBLY PROCEDURES

1. Pull back the hose protector to expose wrench ats. Us-

ing a 9/16” wrench, unscrew the MP hose from the rst

2. Using a 4mm hex key, unscrew the HP (19) and MP

(10) port plugs. Remove the o-rings (9, 20) from the

port plugs.

3. Remove the yoke screw (21) and dust cap (18). Thread

a rst stage vise mounting tool (pn 5116230) into the

HP port.

4. Secure mounting tool in a vise. Using a large adjustable

wrench, remove the inlet tting (16) and the yoke (17).

Remove the yoke washer (13).

5. Remove the o-ring (15) from the inlet tting (16). Insert

the extraction tool (pn 109437) through the center hole

of the inlet tting and push out the conical lter (14).

6. Remove the recessed o-ring (9) from the inside of the

inlet tting (16).

7. Turn the regulator in the vise so that the piston cap (2)

is facing up. Using a large adjustable wrench, remove

the piston cap. Remove the vise mounting tool.

8. Insert the handle end of the extraction tool into the

threaded end of the body (8) and push out the crown

orice (12). Remove the o-ring (11) from the crown

orice.

NOTE: Before performing any disassembly, refer to the

exploded parts drawing, which references all mandatory

replacement parts. These parts should be replaced with

new, and must not be reused under any circumstances

regardless of the age of the regulator or how much use it

has received since it was last serviced.

CAUTION: Use only a plastic or brass o-ring remov-

al tool (pn 944022) when removing o-rings to prevent

damage to the sealing surface. Even a small scratch

across an o-ring sealing surface could result in leak-

age. Once an o-ring sealing surface has been dam-

aged, the part must be replaced with new. DO NOT

use a dental pick, or any other steel instrument.
