DISASSEMBLY
The following disassembly procedure is presented for
reference purposes and presupposes that a major rebuild
of the Bendix
® AD-9 ® or AD-9 ® IPC air dryer is being
undertaken. Several replacement parts and maintenance
kits are available which do not require full disassembly. The
instructions provided with these parts and kits should be
followed in lieu of the instructions presented here. Refer
to Figures 7, 8 and 9 during disassembly.
Caution: While performing service on the AD-9 ® and
AD-9 ® IPC air dryers, it is not recommended that a
clamping device (vise, C-clamp, etc.) be used to hold
any die cast aluminum component, as damage may
result. To hold the end cover, install a pipe nipple in
the supply port and clamp the nipple into a vise.
Delivery Check Valve Removal
The current style AD-9 ® air dryer end cover has a horizontal
delivery check valve while earlier styles contained a vertical
design. Identify the style of AD-9
® air dryer end cover and
proceed to the appropriate step for removal. See Figure
7, illustration E.
1. Vertical Delivery Check Valve Removal – Using an
adjustable wrench or a 1-3/4" socket, remove the
delivery check valve assembly and o-ring. Remove
the o-ring from the check valve assembly.
Horizontal Delivery Check Valve Removal – Remove
the delivery check valve plug from the air dryer end
cover.
2. Remove the spring, check valve body, and o-ring.
