When replacing the older version with the new flywheel the position of the engine speed (RPM) sensor wires must be reversed in the connector at the
engine harness. If the wires are not reversed the vehicle will not start after the new flywheel is installed.
Note:
If the replaced flywheel is of the same type as the new one, there is no need for changing the position of the engine speed (RPM) sensor wires.
Please make the following notation in the above sections of the Service Manuals:
"See Service Bulletin 2-28-820, when changing the flywheel on model year 1992 - 1995".
Older flywheels (A)
have holes drilled in them which provide the engine speed (RPM) sensor with signals.
The new version of the flywheel (B)
has milled grooves which provide the engine speed (RPM) sensor with signals.
The method of replacing the flywheel is contained in:
