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.
