ACE Controls 4" Bore Self-Compensating - Manual

Installation Instructions
4” Bore Self-Compensating Shock Absorber
GENERAL
Install the ACE Self-Compensating Shock (Figure 1)
on a surface of sufficient strength. Align the shock
absorber rod end button with the load striking surface.
This avoids side loading (5 degrees maximum). Use the
full stroke of the shock absorber up to and including an
additional .03 inch (0.8 mm) and provide a solid
mechanical stop to prevent bottoming out. To allow
maximum heat dissipation, DO NOT PAINT THE SHOCK
ABSORBER. If necessary, guard the shock absorber to
protect it from foreign materials such as acids, steam,
weld flash, etc. Applications using two or more self-
compensating shocks should have the load balanced
between them equally.
SELF-CONTAINED MODEL INSTALLATION
All standard 4” bore self-compensating shocks are
prefilled with ATF oil and are ready for use after proper
installation.
AIR-OIL TANK INSTALLATION
Models CAA and CSA 4” bore self-compensating
shocks are prefilled with ATF oil but, MUST BE
CONNECTED TO AN AIR-OIL tank before use. Install
(Figure 2) 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 must be equal to, or greater than,
that of the port in the shock absorber. Do not put a shut
off valve or check 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 oil (taking care to avoid overfilling)
and charge the system to between 50 - 100 psi.
SIDE FOOT MOUNTING INSTALLATION
Bolt the shock absorber (Figure 3) to the mounting
structure using bolts listed. Be sure to securely tighten
the bolts. PLACE A KEY BEHIND THE REAR FOOT
BAR TO PREVENT MOVEMENT OF THE SHOCK
ABSORBER.
Maximum efficiency of operation can be obtained by
carefully following these instructions:
