This article has been updated with bulletin No.: 47-61-31.
CRANKSHAFT BALANCER BOLT TORQUE
The new crankshaft balancer torque specification is 160 Nm (118 lb.ft.). This torque specification applies to all engines equipped with a WASHER FACE BOLT (see Figure 1) along with a separate washer.
This washer face bolt replaces the PREVIOUS STANDARD HEAD BOLT (see Figure 2) and separate washer arrangement which has a torque specification of 95 Nm (70 lb.ft.).
Whenever servicing a crankshaft balancer held by a washer face bolt, use the revised 160 Nm (118 lb.ft.) torque specification.
If servicing a crankshaft balancer with the standard head bolt, use the 95 Nm (70 lb.ft.) torque specification.
