Inner Wheel Bearing Recommendation for a Number 84 Spindle  

Updated 10/27/2014 | Published 10/26/2014

Question:

I noticed that my spindle has two different bearing/race diameters. The inner bearing has to go over about 1/8inch lip. I bought two sets of the 1inch ID bearings. When I removed the old ones I only had the outer race and bearing left on the left axle. I watched the video and I saw that a flat washer was supposed to be on it. All that I had was a little serrated ring. Can I use a flat washer this time with the outer bearing? Do you folks sell them?

The inner and outer bearing surfaces on a number 84 spindle are different diameters. The outer bearing will ride on a 1.00 inch diameter surface and the inner bearing will ride on a 1.378 inch surface.

It sounds like you have the correct outer bearing and now are in need of the correct inner bearing. For that you would want the part # L68149 that you referenced.

You will want to use a spindle washer. The washer protects the back side of the bearing from the edges and points on the back side of the spindle nut.


There are several types of spindle washers available depending on the spindle configuration on your trailer.

The Washer For 1 inch Spindle, # SW1000, is typically used on spindles that have a castle nut, like # 165686, and a cotter pin, # 165649.

A D washer, # 5-23, would be used on a spindle that has a flat side and uses the same castle nut and cotter pin setup.

A Tongue Washer, # 165863, would be used on a spindle with a groove cut through the threads, and would use the same castle nut and cotter pin setup.

A Tang Washer, # 5-101 or # 5-71, could be used with a spindle that has a D shape or a groove, and no cotter pin. The tang on this type of washer is bent up in one or places to prevent the spindle nut from turning and a cotter pin is not needed.

Before installing spindle washers on your trailer, you should check the outer bearing for damage. If you see grooves or scarring of the bearing, you should replace the outer bearing and remove and repack the grease, # L11380, in the trailer hub.

I have added a video on repacking bearings to the right.
