ASSEMBLY
1. Prior to assembly, lubricate all o-rings, seals, and pistons,
as well as body and cover bores, using silicone lubricant.
2. Install the piston stop ring(35), then both the large and
small diameter o-rings(33 & 34) on the blend back
piston(32), then insert the small diameter of the
proportioning piston(32) into the bore in the cover(3). Do
not cut or pinch the o-rings.

3. Install the small and large diameter o-rings (30 & 31) on
the inlet seat(29) then insert the inlet seat into the bore
in the cover(2).
Depending on the configuration/kit being installed:
4a. Install the small and large diameter o-rings (27 & 28) on
the check valve seat(23). Then install the spring(26) on
the inlet seat(29) so that the small diameter fits over
and around the air passage through the center of the
inlet seat. Install the check valve(24) and valve guide(25)
in the check valve seat(23). Note; The check valve must
be installed so that the top hat portion fits into the valve
seat(23). Install the valve guide(25) so that its flange
contains (surrounds) the coils of the large end of the
spring(26), when the valve seat (23) is installed in the
cover(3). Use a small amount of grease to hold these
parts in the valve seat (23). Install the assembled valve
seat(23) with the check valve and valve guide(24 & 25)
into the cover(3) bore and while holding it in place install
the retaining ring(22). Make certain the retaining ring is
fully seated in its groove.

OR,
4b. Install the o-ring(34) onto the plug(35). Install into the
cover(3) bore and while holding it in place install the
retaining ring(22). Make certain the retaining ring is fully
seated in its groove.
5. Install the valve retainer(10) on the inlet and exhaust
valve(11) so that the flange of the retainer(10) surrounds
the rubber portion of the valve. Install the inlet and exhaust
valve in the body(4).
6. Install the inlet and exhaust valve return spring(9) in the
body(4).
7. Install the large and small diameter o-rings(7 & 8) in the
exhaust cover(6), then install the exhaust cover in the
body(4) taking care not to damage the o-rings. Hold the
exhaust cover in place.
8. While depressing the exhaust cover(6), install the
retaining ring(5) in the body(4). Make certain the
retainer(5) is fully seated in its groove in the body.
9. If the valve was equipped with a relay piston return
spring(20), install the spring in the body, large diameter
first.
10. Using lubricant to hold them in place, install the large
and small sealing rings(18 & 17) on the cover(3).
11. Install the o-ring(21) on the relay piston(19), then install
the piston in the body(4).
12. Note the relationship marks made prior to disassembly,
then install the cover(3) on the body(4). Secure the cover
on the body using the two, short cap screws(16). Again,
noting the relationship marks, secure the bracket(15)
on the cover(3) and body(4) and using the two long cap
screws(12) and two nuts and washers(13). Torque the
four cap screws to 120 to 150 lb. in.
13. Install the two cap screws(14) that secure the bracket(15)
to the cover(3) and torque to 180-220 pound inches.
14. Noting the relationship marks made during disassembly,
secure the controller(1) or cover plate to the cover(3)
using the four cap screws(2). Torque the four cap screws
to 50-80 pound inches.
15. Install all air line fittings and plugs making certain thread
sealing material does not enter the valve.
16. Install the rebuilt valve on the vehicle and perform the
OPERATION AND LEAKAGE TESTS before placing the
vehicle in service.
