Condition |
Crankshaft sprocket may disengage from crankshaft during Crankshaft Balancer removal. |
|
Cause |
Crankshaft sprocket may stick to the Crankshaft balancer during removal. |
Anytime that the crankshaft balancer (1) is removed for service, be careful not to pull the crankshaft sprocket (2) off of the end of the crankshaft due to the balancer sticking to the sprocket.
Loosen the crankshaft balancer bolt a few turns and then strike the crankshaft balancer with a rubber mallet to separate the crankshaft balancer from the Crankshaft sprocket.
Caution: Do not rotate the crankshaft on these engines with the crankshaft balancer removed. The crankshaft balancer and bolt must be reinstalled to avoid damage to the crankshaft sprocket, crankshaft and valvetrain.
Once the two components are separated, proceed with repair / diagnosis.
