Can a torque wrench be used to tighten a locknut?
Can a torque wrench be used to tighten a locknut?
When the lubricated locknut is tightened with a torque wrench, there should be a rise in the reading and then a sharp drop as outboard ring shifts and the two rings come together. The nut is now tightened till the torque value is reached. Is this with or without the use of a tabbed lock washer?
What are the torque values for a lock nut?
The “tight” inner ring fit required by high speed will increase preload, requiring an adjustment to bearing face offset or spacer offset to decrease nominal preload and arrive at the desired installed preload. The torque values I included above were for a standard lock nut with a tab lock washer.
Can a lock nut retain a bearing ring?
Lock nuts can’t be trusted to “retain” a bearing inner ring under many loading/operating conditions. The shaft and housing fits (clearance, interference, how much ) need to be carefully considered. The nut also has to provide clamping in excess of the thrust involved.
How does torque work on a Land Rover?
Torque values are given by Land Rover for specific nuts and bolts around the vehicle to ensure that they do not come loose during use. Torque wrenches can deviate over time so should be recalibrated regularly to ensure their torque settings are correct. New bolts must be installed.
What should the adjusting nut be torqued to?
Torque the adjusting nut to 200 lbf-ft to seat the bearing components. Always rotate or oscillate the wheel while torquing the adjusting nut to ensure that the rollers are fully seated against the cone large rib. 2. Back off the adjusting nut one full turn or until it’s loose. 3. This is where you actually establish end play.
How is nut torquing and back-off used to set wheel bearings?
1. Torque the adjusting nut to 200 lbf-ft to seat the bearing components. Always rotate or oscillate the wheel while torquing the adjusting nut to ensure that the rollers are fully seated against the cone large rib. 2. Back off the adjusting nut one full turn or until it’s loose.
How much torque does a 4WD axle nut have?
Tighten to 111 ft-lbs/150 Nm. Loosen 45° then retighten to 199 ft-lbs/270 Nm. 4WD 1980-1991 With manual locking hubs: Tighten adjusting nut to 50 ft-lbs/68 Nm while turning hub. Back off and retighten to 50 ft-lbs/68 Nm. Back off to 0. Install ring and tighten locknut to 160 ft-lbs/217 Nm minimum. Tang on ring must press through slot on spindle.
