IMPORTANT:
IMPORTANT:
Apply grease or clean engine oil to the inside of the crankshaft balancer or the end of the crankshaft, to prevent galling during assembly.
IMPORTANT:
Apply the lubricant that comes with J 42845
each time the tool is used. Failure to lubricate J 42845
may prevent the balancer from installing completely.
NOTE:
Ensure the crankshaft balancer is installed to the proper depth. The crankshaft balancer nose must be seated against the crankshaft sprocket. Failure to install the crankshaft balancer properly may result in improper torque to the crankshaft balancer bolt. An improperly torqued crankshaft balancer bolt may loosen causing serious engine damage.
