Air-Oil Tank Installation Instructions
CAA & CSA Self-Compensating and
AA & SA Adjustable 2” & 3” Bore Series
Maximum efficiency of operation can be obtained by
carefully following these instructions:
Figure 1
AIR-OIL TANK INSTALLATION (Figure 1)
Self-compensating models CAA and CSA as well as
adjustable models AA and SA are pre-filled with ATF
but must be connected to an air-oil tank before use.
Install the proper ACE air-oil tank as close as possible to,
and physically higher than the shock absorber. The line
connecting the shock absorber to the air-oil tank must
be free of kinks and loops. The inside diameter of this
line must be equal to, or greater than, that of the port
in the shock absorber.
Do not put a shut-off valve between the shock
absorber and the air-oil tank. Install a check valve in
the air line to the air-oil tank and plug the extra ports of
the tank. Fill the tank with ATF to the fill mark and charge
the system to between 50 - 100 psi (3.4 - 6.8 bar).

AIR EXHAUST CIRCUIT FOR MODELS CAA and
AA SHOCK ABSORBERS (Figure 2)
If the rod is to remain in the shock absorber after
decelerating the load, this type of installation is
necessary. Avoid overfilling the air-oil tank. If not built in,
a special ACE check valve should be used to eliminate
misting of oil out of the air-oil tank.

RE-CIRCULATING COOLING CIRCUIT FOR
MODELS CAA, CSA, AA and SA (Figure 3)
This type of installation may be required when ambient
temperatures and/or cycle rates cause the shock absorber
to heat up beyond 200 F (93 C).
0 0
Use 250 psi (17 bar) check valves with a low cracking
pressure of 5 psi (0.34 bar). If a filter is to be used in this
circuit, a 30 to 40 micron filter element with a 5 psi (0.34 bar)
by-pass is recommended. Consult factory for assistance.
