General Torque Information
Mismatched or incorrect fasteners can result in damaged or malfunction, or possible injury.Take care to avoid mixing metric dimensioned fasteners and inch dimensioned fasteners.
Prior to installation of any hardware, ensure that components are in near new condition. Bolts and threads must not be worn or damaged. Threads must not have burrs or nicks. Hardware must be free of rust and corrosion. Clean the hardware with a noncorrosive cleaner. Do not lubricate the fastener threads except for the rust preventive. The rust preventive should be applied by the supplier of that component for purposes of shipping and storage. Other applications for lubricating components may also be specified in the Service Manual.For additional torque specifications, not included in this section, refer to Torque Specifications, SENR3130, available from your Caterpillar dealer.Standard Torque for Inch Fasteners
The following charts give general torques for bolts, nuts, and taperlock studs of SAE Grade 5 or better quality.

Inch Taperlock Studs
Standard Torque for Metric Fasteners
Be very careful never to mix metric with U.S. customary (standard) fasteners. Mismatched or incorrect fasteners will cause machine damage or malfunction and can result in personal injury.Original fasteners removed from the machine should be saved for reassembly whenever possible. If new fasteners are needed, they must be of the same size and grade as the ones that are being replaced.The material strength identification is usually shown on the bolt head by numbers (8.8, 10.9, etc.). The following chart gives standard torques for bolts and nuts with Grade 8.8.
Metric hardware must be replaced with metric hardware. Check parts manual for proper replacement.Metric Nuts and Bolts

Standard Torque for Worm Drive Band Hose Clamps
Typical hose clamp. Standard Torque for Constant Torque Hose Clamps
Use a constant torque hose clamp in place of any standard hose clamp. Ensure that the constant torque hose clamp is the same size as the standard hose clamp. Due to extreme temperatures changes, the hose will heat set. Heat setting can cause hose clamps to loosen. Loose hose clamps can result in leaks. There have been reports of component failures that have been caused by hose clamps that have loosened. The constant torque hose clamp will help prevent these failures. Use a torque wrench for proper installation of the constant torque hose clamps. The constant torque hose clamp is installed correctly under the following conditions:* Screw tip (1) extends 6.35 mm (.250 inch) (X) beyond the housing.* The belleville washers are collapsed nearly flat after screw (2) is tightened to a torque of 11 1 N m (98 9 lb in).Torques for Ground Engaging Tool Bolts
