6. Install the lever assembly (key 9) on the valve
stem (key 13) and secure the lever assembly
(key 9) with the machine screws (key 11).
7. Install the diaphragm head gasket (key 7), lower
diaphragm head (key 24), diaphragm (key 5),
and upper diaphragm head (key 6) on the pusher
post (key 8) and attach with the hex nut (key 37).
Tighten using 30 to 45 ft-lbs / 41 to 61 N•m
of torque.
8. Install the pusher post (key 8) plus attached
diaphragm parts onto the lever assembly (key 9).
9. Install the spring case assembly (key 23) and control
spring (key 1) on the diaphragm casing (key 20)
so that the vent assembly is correctly oriented,
and secure them with the spring case cap screws
(key 21) and hex nuts (key 22), finger tight only.
10. Install the upper spring seat and the adjusting nut
(key 2) turning clockwise until there is enough
control spring force to provide proper slack to the
diaphragm (key 5) and attached parts. Using a
crisscross pattern, finish tightening the spring case
cap screws (key 21) and hex nuts (key 22) using
55 to 75 in-lbs / 6 to 8 N•m of torque. Then finish
turning the adjusting nut (key 2) to the desired
outlet pressure setting.
11. Install a replacement closing cap gasket (key 35) if
necessary, and then install the closing cap (key 3).
Type Y696VRM Vacuum Regulator
1. Remove the closing cap (key 3) and turn the
adjusting nut (key 2) counterclockwise until all
compression is removed from the control spring
(key 1). If the only further maintenance is to change
the control spring (key 1), skip to step 10.
2. Remove the spring case cap screws (key 21) and
hex nuts (key 22) and remove the spring case
(key 23).
3. Remove the diaphragm (key 5) and attached
parts by tilting it so the pusher post (key 8) slips
off the lever assembly (key 9). To separate the
diaphragm (key 5) from the attached parts, unscrew
the diaphragm hex nut (key 37). If the only further
maintenance is to replace the diaphragm parts or
change the control spring (key 1), skip to step 8.
