End Cap Checks
All end caps, even new ones, should be checked as follows. See Service Bulletin for more information.
Check Valve Bleed Hole Diameter
1. Remove the condenser pressure bypass check valve snap ring, stem, spring, and piston from the end cap.
2. Use a number 43 (0.089 in. [2.26 mm]) drill bit to check the size of the hole from the end cap gasket face to the check
valve piston bore as shown.
3. If the drill does not go all the way into the bore, drill the hole completely through.
4. Deburr the hole in the check valve piston bore. A used drill bit can be modified to use as a deburring tool.
