U-Bolt Torque Guide
U-Bolts that bave ben torqued to a set preload are recommended to be re-torqued after a short time to take up the stretch in the material.
U-Bolts that have been well lubricated with an anti-sieze compound will have a torque range between plated and unplated values.
All of the below values are general guidelines. The OEM Service Manual on specific models always takes precedence over the values shown.
| Size | Material Grade | Max. Torque Ft.-Lbs. Plated | Max. Torque Ft.-Lbs. Unplated |

U-Bolts must be tightened and torqued using a cross pattern sequence.
Tighten #1 then #4 to partial toque, then partial torque #2 and #3.
Using the same sequence, fully torque U-Bolt Nots.
DO NOT RE-USE U-BOLTS.
