A new crankshaft balancer is now available for use on the above models. 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 Number 25523502. The new longer bolts should always be used
when replacing the balancer.
