Harmonic Balancer - Crankshaft Pulley: Specifications
This article has been updated with bulletin No.: 57-61-34A.
NEW HARMONIC BALANCER INSTALLATION
1996 model year engines are equipped with a smaller diameter M14 crankshaft balancer bolt, which replaces the larger M18 bolt. Since this new bolt
is smaller in diameter, Kent Moore tool number J 39344 is no longer used on 1996 model engines. A new harmonic balancer tool J 41998 is now
available and must be used whenever installation of the harmonic balancer is necessary. This new bolt has a revised torque specification of 50 Nm (37
lb ft) plus 120° for installation.
IMPORTANT:
A small number of 1995 engines were built with crankshafts equipped with the M14 bolt. Identify the size of the bolt to determine the proper
torque specification.
