Crankshaft Position Sensor: Adjustments

Fig. 39 Adjusting ignition timing with crankshaft angle sensor:

1. Connect inductive type timing light to No. 1 cylinder high tension lead, following manufacturer's instructions.
2. Loosen bolts securing crank angle sensor to adjustor, Fig. 39.
3. Start engine and check timing at specified idle speed.
4. To advance timing, turn adjuster screw, Fig. 39, clockwise, moving sensor upward. To retard timing turn adjuster screw counterclockwise, moving sensor downward.

Fig. 40 Crankshaft angle sensor adjustments:

Fig. 41 Adjusting crankshaft angle sensor radial dimension "S":

5. Stop engine. Tighten crank angle sensor mounting bolts and check radial direction dimension adjustment.
6. To adjust dimension "S", Fig. 40, loosen crank angle sensor adjuster bolts, Fig. 41.
7. Using a thickness gauge, set dimension as shown in Fig. 41 to .039 -.055 in. and tighten adjuster mounting bolts.
8. To adjust dimension "R", Fig. 40, loosen air conditioning compressor and loosen four compressor Racket mounting bolts.

Fig. 42 Adjusting crankshaft angle sensor axial dimension "R":

9. Place .047 in. thickness gauge between signal disc plate and bracket Fig. 42, and tighten compressor mounting bolts.
10. Insure that dimension "R" is .039-.055 in. Tighten compressor mounting bolts making sure belt is tensioned correctly and recheck ignition timing at specified idle speed
