A new crankshaft balancer is now available for use on the above engines. This new balancer requires the use of longer bolts for attaching the crankshaft
pulley to the balancer.
For this reason the longer bolts required will be packaged with the balancer under part no. 25523502 for regular aspirated engine and part no. 25523503
for Turbo engines. The new longer bolts should always be used when replacing the balancer.
