assembly to crankcase posts.
2. On engines with earlier design bracket, snug screws
and check air gap of sensor with a feeler gauge. It
must be 0.20-0.70 mm (0.008-0.027 in.). Torque
bracket screws to 9.7 N·m (86 in. lb.).
On engines with later design bracket, secure bracket
assembly to crankcase posts. Torque bracket screws
to 7.3 N·m (65 in. lb.)
3. Check electrical connector on crankshaft position
sensor making sure a good connection is made.

screws. Torque screws to 10.4 N·m (92 in. lb.).
2. Apply a small amount of Loctite
to external threaded section, (unless new parts with
preapplied locking compound are being used).
Thread debris screen hex studs into mounting holes
in fl ywheel. Torque each stud to 21.5 N·m (190 in.
lb.).
