 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.
