ASSEMBLY - Continued e. Check for piston pin end clearance by cocking connecting rod and shifting pin in bushings. NOTE Clean piston surface around piston pin replacer before measuring replacer leakage. f. Check each piston pin replacer for proper sealing with vacuum gage tester (Figure 11, Item 23). Place suction cup over replacer and hand operate lever to pull a vacuum of 10.0 inches (254 mm) of mercury on gage. A drop of more than 5.0 inches (127 mm) of mercury in gage reading over 10 seconds indicates air leakage at replacer. 23 MAINT_363 Figure 11. Piston Replacer Sealing Check.
