AIR-OIL TANK INSTALLATION (Figure 1)
Self-compensating models MCA and MCS as well as
adjustable models MAA, MAS, MLA and MLS 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, with the rod
extended, and charge the system to between 50-100 psi
(3.4 - 6.8 bar)
AIR EXHAUST CIRCUIT FOR MODELS MCA, MAA
and MLA SHOCK ABSORBERS (Figure 2)
If the rod is to remain in the shock absorber after
decelerating the load, this type of installation is
necessary. If not built in, a special ACE check valve
should be used to eliminate misting of oil out of the
air-oil tank.
PROPER AIR-OIL TANK SIZE
Refer to the chart below for proper air-oil tank size in
relation to the specific Magnum Group series.
