    2006 Raptor 700 Axle Nut Torque

    The New Twin Row Axle Bearing Carriers sometimes are missing the Spacer and others the Spacer is not in contact with the inner races of the Twin Row Bearings. If you apply any torque to the axle nuts (there are several types depending which axle you have) the inner race of the bearing will be forced sidewise against the outer race. Now if the Spacer was tight against the inner race, any torque on the axle nut will compress the two inner races against the spacer with no side load on the two outer races from axle nut torque.


    How do you guys set up those New Twin Row Bearings where there is clearance between the spacer and inner races?

    Or was that spacer suppose to be tight compressing the spacer between the two inner races?

    One from Caltric that had a center spacer that was 1/4 inch too short, and one from fx4kingxit ( Black Path) in which center spacer was missing completely. The last one from partsdiscounter (NICHE) said it had spacer and it did but just a small spacer/bearing end play which Bearings I installed.

    I removed axle again after considerable torque on the axle nut and checked the end play on the center spacer (which remained about 1/32"). I reinstalled the axle with two "O" rings compressed between the left and right (Chain Sprocket/Brake Rotor) and inner Races of the left and right Bearings as shown in the Axle Assembly Stock Illustrations. I applied a gentle torque to the Axle nut to compress the "O" rings just a tad. Albiet the Spec suggests 175 ft-lbs torque on the Axle Nut.

    What is strange is the spacer is not long enough and what is really strange is one Billet Aluminum Bearing Hub did not have a center spacer at all. If you were to grease the center zerk it would just fill the large void inside the Bearing Hub around the axle. Those three Billet Aluminum Bearing Hubs I received are just a poor design or poor assembly or BOTH.

    Of those three Billet Aluminum Bearing Hubs there are approximately 900 sold on Ebay and no one has mentioned the Bearing Center Spacer Issue? The Axle Nut is suppose to be torqued to 175 ft-lbs which if that is done would basically destroy a bearing with that much side load on the inner race, Bearing, and against the outer race in a short period of time.

    I cannot imagine torqueing the axle nut to stock specs without damaging the outer race with any of the three Billet Aluminum Hubs.

    I must be missing something as there are a total of approximately 900 of these three Billet Aluminum Axle Hubs sold on Ebay and no one is bringing up issues
