With the safety chamber under pressure, and the safety piston in a retracted position, run the flange nut up snug on the push rod and install the clevis yoke. Maintain a distance of 2 1 %6 ± VLQ of an inch between the centerline of the clevis pin holes in the yoke, and the mounting flats of the cylinder assembly. Tighten the flange nut against the yoke to lock it in place. FAIL-SAFE UNIT DISASSEMBLY 1. Loosen the housing to cap set screws, and unscrew the housing from the cap (Figs. 7 and 8).

If the Fail-Safe piston seal is worn or damaged, replace the entire piston assembly. 3. If the housing cap assembly is damaged, replace the complete cap assembly. Do not attempt to remove the spring from the assembly. Serious injury could result. Inspection. Check all components for wear or damage and replace as necessary. Clean all parts.
