TM 9-2815-220-24 FUEL INJECTION ADVANCE CONTROL TEST 0162 00 ADJUSTMENT PROCEDURE NOTE If the advance varies more than 2 degrees at 300 rpm when the oil pressure drain button is depressed, the advance should be retarded slightly. This variance indicates the mechanical retard stop is not in phase with the hydraulic valve. If advance unit fails to pass the test, it may be adjusted by rotating the adjusting ring (32). Note whether advance unit advances too soon or too late. Either condition can normally be corrected by rotating the adjusting ring. Do not turn the adjusting ring more than 1/16 inch (1.5875 mm) during any one adjustment. 32 WP 0162 00-12
