3.
Install 1U8869 Digital Dial Indicator (9) in the collet of
4C4716 Timing Fixture (2). Leave the collet loose.
4.
Put the dial indicator and timing fixture (2) on the
1U8702 Injector Timing Block (3) and 1U6678
Calibration Fixture (4) as shown. Make sure locating pin
(C) in left side of timing fixture (2) engages hole in
calibration fixture (4). Install bolt (B) on the right side
and tighten to secure timing fixture (2) firmly to
calibration fixture (4). The long pin of timing fixture (2)
must be in the hole located in the center of injector
timing block (3). The ends of the injector timing block
and surface of calibration fixture must be clean.
