Recommended Grease Cap With Grease Fitting  

Updated 08/17/2022 | Published 08/15/2022

Question:

I saw the question about the trailer 1 15/16inch 1.9375 dust cap with the replacement part being the Fulton F001524 however, I am looking for a cap that also has the grease fitting so I can grease everything without taking it apart. I only use to the trailer to haul my lawn tractor, etc. No usage in water. My current dust caps have almost a knife edge and the ones I have seen in stores are almost are thicker. Ive also heard the spring loaded caps with grease fittings push grease out the back and fling it all over the wheels. Really not looking for that mess either. Any recommendations would be appreciated.

Since I'm assuming you don't have an E-Z Lube axle or some equivalent with the zerk fitting on the end of the spindle, the only option would be to use a Bearing Buddy. What you have heard about the grease getting pushed out of the back only happens if they are overfilled. As long as you make sure to not add too much grease this will not be an issue.

Before choosing a Bearing Buddy I recommend measuring the hub bore diameter. I would also use a digital caliper like the # PTW80157 since this is a precise measurement and a tape measure isn't accurate enough. If you are just slightly off that is fine since this is a drive in installation. Based on your grease cap you will need one of the following:

-1.938" hub bore # BB1938SS

-1.968" hub bore # BB1968SS

-1.980" hub bore # BB1980A-SS
