NOTES
• ACR is used only on 103 cu. in. and larger engines.
• See Figure 7-61. The tip of ACR solenoids for Twin-Cooled engines are approximately 0.500 in (13 mm) longer than those for air-cooled engines. Twin-Cooled ACR’s will contact the pistons of an air-cooled engine.
See Figure 7-62. The ACR is opened and closed by the ECM to assist starting.
See Figure 7-63. When open, compressed gases are released through the exhaust port.
Twin-Cooled models: ACR service requires the removal and installation of the upper coolant hoses to access the rocker covers. See C.5 COOLING SYSTEM REPAIR, Upper Coolant Line Removal.
