CF = Consult Factory Warning: If components show significant deterioration to abrasion, damage, or corrosion, the assembly should be removed from service. Failure to periodically perform inspection for abrasion, damage, or corrosion may lead to failure and/or rupture of the assembly resulting in property damage, serious personal injury, or death. Bolt Torque Information Bolts should be tightened using the following torques as a guide and with well lubricated threads.
