What is the Bore Size of the Dexter Trailer Hub and Drum Assembly # 84557UC3


What size is the bore of the brake drum where the cover fit in.. 1.980 is std. I think. Thanks


Helpful Expert Reply:

A 1.98 inch inner diameter bore is pretty common on trailer hubs. If you were to measure the bore diameter of the Dexter Trailer Hub and Drum Assembly, # 84557UC3, using a dial caliper, you would get 1.96 inches. This hub requires a grease cap with a 1.98 to 1.99 inch diameter. The grease cap that comes with this hub actually measures 1.99 inches.

If you are looking for a replacement dust cover, you have many options. For a standard dust cover, you can use part # F001518 or # RG04-020. If you have EZ lube spindles, then you can use part # RG04-040 (this is a set of 2) or # DC200L-DCRP (single). If you would like bearing protectors that include a grease fitting, then you can use the Bearing Buddy Bearing Protectors, # BB1980A-SS (stainless steel), # BB1980A (chrome plated), or the Kodiak Red Eye Bearing Protectors, # KREB1980AC.

If you have standard spindles (without a grease fitting), I would recommend going with the Bearing Buddy Bearing Protectors, # BB1980A-SS. These are stainless steal bearing protectors that make greasing the bearings easy.
