13.2 Trantorque Installation Procedures
Shaft and bore diameters along with surface finishes are critical for the proper installation of a Tran-
torque bushing. These specifications are held at the factory during manufacturing. If it is necessary
to disassemble and reassemble a Trantorque application that is undamaged and intact the following
procedures will insure a positive installation. If it is necessary to replace a unit in which the Tran-
torque or shaft may have come loose, rotated or been damaged, a thorough inspection of the com-
ponents is necessary to insure the failure will not reoccur.
CAUTION: Do not use lubricants in this installation. The use of any lubricant on the contact surfaces
may result in bushing failure and will void all warranties
1. Both the shaft and component bore must be completely free of paint, grease, oil, dirt, and burrs.
Clean the surfaces with a non
- petroleum based solvent such as isopropyl alcohol.
2. Insert the Trantorque into the bore making sure the mating hub is flush against the shoulder at
the hex flats.
3. Insert the shaft fully and hand - tighten the nut until the assembly becomes snug on the shaft.
IMPORTANT: The shaft must fully engage the gripping area of the Trantorque.
4. Using a torque wrench, tighten the nut to the proper torque shown in Table 13 - 1.
IMPORTANT: A torque wrench must be used! An impact wrench will not yield the proper torque
and the installation will fail. Minimal under - tightening will allow the Trantorque or shaft to spin in
the bore. Over - tightening will damage or crack the Trantorque. Do not use an impact wrench dur-
ing installation.
