etrailer is the ONLY place I could find this part, so if I could give ten stars, I would! Good quality part and quick shipping, exactly what I was looking for.

After a year, everything is still working perfectly! Couldnt have asked for a better part and will be looking here for any needs in the future!



by:

I have a 30+ year old boat trailer that needed a new hub dust cover due to one being lost. I replaced both and have one for a spare. They worked fine. etrainer was the only place that I could find the size I needed. Picture is boat that is "work in progress"!Thanks etrainer!



by:

they are thicker material, good quality. I like them a lot



by:

A simple bearing pack on an early 50's travel trailer axle turned nightmare. My local guys just said sorry. However, etrailer had the parts in stock at a great price. The site is very user friendly. What made finding the right parts easy was their excellent and complete listing of sizes and dimentions of seals, bearings and hub caps etc. that I needed. I found the parts to be of high quality. This combined with unprecedented customer service and fast shipping has earned them my future business. I would highly recomend them as a go to site for all your trailer needs. THANKS.



by:

It was the part I ordered. It was just not a good fit, though. I have an old hub from a farm harrow that I'm having trouble finding correct parts for.



by:

Got the part right on time. Excellent service!!!



by:

I needed dust caps for a 1965 Dodge Coronet, but all those that are available thru auto supplies and restoration shops did not fit. After searching the web with the dimensions of the caps I needed, I found these at etrailer. The lip which fits into the hub was about 1/8" too long, so I machined it down to fit. The caps were too shiny. I needed them to look like the original factory galvanized ones. I glass beaded them and painted with cold galvanized spray. Turned out very nice and look like original 1965 Dodge Coronet ones.



by:

Exactly what I needed.



by:

It fit my boat trailer. Received timely and got excellent service!



by:

Just what I ordered. Tks



by:

Needed new grease caps for a log splitter, wasn’t, having luck finding them local. I checked out e-trailer and they had what I needed, as always with etrailer the part was received in a few days and worked as it should. After a year it’s still working well



by:

Exactly what I needed! Spent quite a while internet searching, checking dimensions of the grease caps offered; but etrailer was only place that had same size as what I needed. Apparently it's a much older style that's not used much anymore. Even though I'd only lost one of the caps I ordered two just to have a spare on hand. Fast service, very economical shipping - no doubt I'll keep this site on my favorites list.



by:

Fit just right for my small trailer. Perfect sizing descrirption. Works great

Still working great.



by:

Purchased these for a 1965 Sears fishing boat trailer. Added chamfer with a Dremel tool to get the leading edge to start into the hubs. Seated caps with a rubber mallet. Nice tight fit.



by:

I went to 5 auto parts stores looking for these caps. Went back to this web site and there they were. Always have been able to find what I needed and fast shipping.

by:

This Item Still was too large but needed to get on road, so I used File arround outside edges of flange to file it down to fit, I'll probaly have a hard time taking it off the next service, but guaranteed it wont just pop off.



by:

I took a chance that these would fit my 50+ year old trailer axle that looks like it came off the front of a tractor.. but they didn't... The product is good but my trailer is too old...



by:

I needed a grease cap for an old handmade utility trailer, this cap will work well with a bit of work.



by:

shipping was quick and product was exactly as described
great service from etrailer

  • Is there a bearing Buddy that Measure 1.786 Inches
    The closest match bearing protectors we have will be either a 1.781 or 1,810. A 1.786 is not available. Make sure you are getting the most accurate measurement of the hub bore that you can. We use digital dial calipers to take these types of measurements. The outside diameter of the bearing protector is usually slightly larger than the hub bore so there is a tight fit. If you do keep coming up with 1.786 the only option we have is grease cap # F001503 that you referenced. Bearing Buddy...

  • Grease Cap Recommendation to Replace Cap that Measures 1.90 Inches
    You would want the part # F001524 which has an outer diameter of 1.943 inches. This would install in your hub and provide a nice tight fit. The part # F001503 would be too small and wouldn't stay in your trailer hub.

  • How to Pick Out a Grease Cap for a Trailer Hub on an Enclosed Trailer
    We have several grease caps that could potentially work for the hub on the axle you have on your enclosed trailer, see link to the right. To pick out the correct size one you will need to know the pilot hole diameter on your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap. Clean the grease off and measure the opening with a dial caliper...

  • Grease Cap Recommendation for Hub with 1-15/16 inch Hub Bore
    The closest grease cap we offer to what you would need is the part # F001524 that is designed to fit hubs that are 1.943 inches. 1-15/16 inches in decimal form is 1.9375 inches.

  • Tools for Installing and Removing Bearings, Races and Seals
    We offer a tool for installing bearings, races and seals, kit # PTW83020 from Performance Tool. This is intended for installing these items but it could also work to get them out of your hubs. Sometimes mechanics will use a socket or piece of pipe sizes to the hub bore for removing old races, bearings and seals. Please refer to the linked video. We also offer dust cap driver tools, shown on the linked page. These are used for installing grease caps/dust caps like # F001503.

  • How to Select Correct Bearing Buddy Bearing Protectors
    You can easily switch from standard grease caps like # F001503 to Bearing Buddy bearing protectors. All you need to do is measure the hub inner bore with a precision caliper like # PTW80157. You will want to measure to the nearest thousandth of an inch, such as 1.234-inches, to select the correct size. Also note whether the bore of your hubs is threaded or smooth; we have Bearing Buddy protectors for both threaded and non-threaded hubs and in many sizes, shown on the linked page.

  • Availability of Axle Hub Grease Dust Cover That Fits Hub Bore of 1.810" Diameter
    The Bearing Buddy Bearing Protectors # BB1810 is currently the only grease cap we have that fits a 1.810" hub bore opening.

  • How to Pick Out a Grease Cap for a Boat Trailer
    Sounds like you are looking for a grease cap for the hub on your boat trailer. You will want to use a dial caliper or micrometer like # PTW80157 to measure the inner diameter of the hub you have on your trailer to determine what size cap would be needed. Check out the picture I attached that shows this measurement being taken on a hub. I attached a link to all the grease caps we offer, once you know what size you need check out the link I attached to see all the sizes we offer.

  • Replacement Hub Grease Cap that Fits Hole 1-7/8 inch
    The closest grease cap we have to the size you mentioned would be the Fulton part # F001503 which fits an inner hub bore diameter of 1.786 inches. This is a little smaller than 1-7/8 inch so I would recommend using a caliper like the part # PTW80157 to verify this.

  • Looking for 45mm Grease Cap
    The grease cap you'll need for your 1.77 inch hub bore is from Fulton, part # F001503. The outside diameter at the base is 1.78 inches which is perfect, as it's meant to fit tightly. I've linked you to a product description video featuring the Fulton grease cap.

The option closest to your quoted 1-1/2 inches is the 1.786-inch size. We offer the Fulton # F001503, which is sold as a single unit.

  • Correct Trailer Grease Cap for 1-3/4" Pilot Hole

  • Replacement Grease Cap Recommendation
    It looks like the Fulton Grease Cap - 1.786" Outer Diameter - 1-9/16" Tall # F001503 is going to be slightly too small for your needs. The closest replacement grease cap we have to your 1.934" OD size is the Fulton # F001524 which is 1.943" OD and 1-3/8" tall. I've linked our entire selection of grease caps to this answer, the next closest size after that is the # TRAG-DC-196 which is 1.957" OD.

  • Correct Dust Caps for 1.78" Hub Bore
    Thanks for sending in your picture and a tape measurement of a 1-7/8" dust cap, but we don't have any dust covers with an outer diameter of 1.875". We have a bearing protector that is 1.78" in outer diameter, which is the Fulton Grease Cap - 1.786" Outer Diameter # F001503.The next size up is a 1.988" dust cap # RG04-020. It's also possible that the hubs on your 1947 International KB-1 Truck have non-standard sizes. I highly recommend picking up a digital caliper like # PTW80157 to get...

  • Replacement Grease Caps For Hub Bore 1.781 With Grease Zerk On Cap For Adding Grease To Spindle
    It appears that you have a Fulton Grease Cap # F001503 that fits a 1.781 hub bore. And that someone put in a Grease Zerk # Gzerk on the cap. If you can confirm that is you hub bore diameter as I cannot tell from your tape measure, you can use the previous cap. Or you can use the Bearing Buddy Bearing Protectors # BB1781SS that are designed to do what your caps are doing.

  • Recommended Grease Cap With Grease Fitting
    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...
