CLEANING & INSPECTION

1. Using mineral spirits, clean and thoroughly dry all metal

parts with the EXCEPTION of the VALVE AND PISTON

ASSEMBLY. The valve and piston assembly contain

o-rings, therefore, wipe the exterior of the exposed areas

avoiding the bore in which the piston slides since a

special high temperature lubricant is used on that

surface.

2. Using a thin wire make certain that the vent holes in the

IRV

valve body and valve and piston assembly are open.

3. Check all metal parts for severe corrosion, pitting and

cracks. Pay particular attention to the valve springs and

valve surfaces. Superficial corrosion and shallow pitting

on the exterior of the cap nut and body is acceptable.

ASSEMBLY

The appropriate lubricant is packaged in Bendix maintenance

kits and should be used as directed in the kit instruction

sheet. Refer to Figure 9 throughout assembly.

1. Lubricate the interior bore of the body and the o-ring

grooves of the valve and piston assembly.

2. Lubricate and install the large and small diameter o-rings

on the valve and piston assembly.

3. Carefully insert the valve and piston assembly into the

body, making certain that it is completely seated and

the valve plate remains visible.

4. Carefully work the small diameter o-ring, which serves

as the valve seat, into the cap nut groove. When properly

installed, this o-ring is evenly retained by the rolled over

crimped edges of the cap nut groove. IMPORTANT: Do

not Lubricate this o-ring or the cap nut groove in

which it is installed.

5. Lubricate the cap nut groove for the large diameter

o-ring. Lubricate, then install the large diameter o-ring

on the cap nut.

6. Install the spacer then the spring in the valve body.

7. Install the cap nut in the body and torque it to between

58 and 72 pound feet.

8. Install the safety valve and valve spring in the IRV

body. Using a 3/16 inch Allen wrench, install the exhaust

plug.

9. Perform the operation and leakage tests before placing

the valve in service.
