A Closer Look: The PreSet Plus Spindle Nut System

     The new ConMet PreSet Plus hub assembly incorporates several enhancements designed to improve the performance and serviceability of the wheel end. One of the most significant additions is a unique spindle nut designed exclusively for PreSet Plus hub assemblies.

 

     The PreSet Plus spindle nut now serves as the shipping cap that retains the outer bearing cone and the bearing spacer in the hub. With the outer bearing cone held in place during shipment and installation, it minimizes the possibility of damage to the outer bearing cone during handling. It also insures that the hub remains parallel to the spindle during assembly, reducing the possibility of the seal becoming cocked in the hub.

 

     This spindle nut is designed to be reusable and last the life of the hub. In the event that replacement becomes necessary, the spindle nuts are available as a complete unit or as individual components that can be replaced as necessary.

 

     Be aware that any warranty offered as part of a PreSet Plus package requires the use of a PreSet Plus spindle nut throughout the life of the hub assembly.

 

     There's no need to replace a PreSet Plus nut unless any of the nut pieces are damaged or worn. A PreSet Plus hub can be identified by its locking snap ring with red lettering located on the outside of the nut.

     If a PreSet Plus spindle nut must be replaced, use only PreSet Plus axle spindle nuts. Part numbers can be found in the ConMet hub service manual. This service manual provides instructions for removing, servicing and re-installing PreSet Plus hub assemblies as well as ConMet's standard and PreSet� hubs. It can be found on ConMet's web site at www.conmet.com. For a hard copy of the manual, contact customer service at 800-547-9473.

 

     Another unique feature of the PreSet Plus hub assembly is the spiral snap ring that retains the spindle nut assembly in the hub. When the spindle nut is loosened and removed from the spindle, it pulls against the snap ring in the hub and acts as a hub puller to help remove the hub and the seal from the spindle.

 

     PreSet Plus hub assemblies are available for FF and FL steer axles, R Drive axles, and TN and TP trailer axles. There are two FF spindle nut variations to accommodate both spindle nut configurations used in the industry today:

     Spindle

       Threads

     FF with D-Flat Washer

       1.50" x 12 UNF

     FF with Keyed Washer

       1.50" x 18 UNEF


     As with PreSet hub assemblies, the PreSet Plus hub assembly is completely serviceable in the field. For additional product and service information about all ConMet products, visit www.conmet.com or call 800-547-9473.
