4. If it is necessary to replace the lever assembly,
remove the lever cap screws (key 18).
5. Install the replacement lever (key 15) into the lever
retainer (key 16) by inserting the lever pin (key 17).
Secure the lever assembly into the diaphragm casing
with the cap screws (key 18) and torque the cap screws
to 7 foot-pounds (9 N•m).
If it is necessary to perform maintenance on the
diaphragm assembly, continue with steps 6 through 11
and step 20 for Type 627, 627H, 627M, and 627HM
regulators, or steps 12 through 19 for Type 627R and
627MR regulators.
Perform steps 6 through 11 for Type 627, 627H,
627M, and 627HM Regulators only:
6. For Type 627, 627H, 627M, and 627HM regulators
(figures 5 & 6), use steps 7 through 11 to disassemble
and reassemble the diaphragm assembly.
7. Remove the diaphragm head cap screw (key 46),
lower spring seat (key 31,Type 627 or 627Monly), and
diaphragm head (key 24). On the Type 627H or 627HM,
remove the diaphragm cap screw O-rings (key 52).
Separate the diaphragm (key 23) from the pusher post
(key 19).
8. Install the diaphragm (key 23), in reverse order in
step 7, on the pusher post (key 19), insert and finger
tighten the diaphragm head cap screw (key 46).
9. Hook the pusher post on the lever (key 15), then
turn the diaphragm (key 23) to match the holes in the
diaphragm with the holes in the spring casing.
10. Unhook the pusher post from the lever and torque
the diaphragm head cap screw (key 46) to 7 foot-
pounds (9 N•m) for the Type 627 or 627M. On the Type
627H or 627HM torque the diaphragm head cap screw
to 14 foot-pounds (18 N•m).
11. Hook the pusher post on the lever (key 15) and
check the hole alignment. If necessary, loosen the cap
screw (key 46) and reposition the diaphragm (key 23)
on the pusher post (key 19). Retorque the screw (see
