Grease cap fits trailer hubs with 1.943" inner diameter.


Bearing caps fit perfect,will order again as needed


perfect fit for a 60+ year old farm implement I'm restoring.


was as described


Good communication


The pair of grease caps I purchased fit perfect. Your website was very helpful by giving me actual dimensions so I could make sure It would be the right part.
The caps went on an old homemade utility trailer with non standard size hubs, and with your large selection I was able to complete my project.
I will highly recommend etrailer to anyone needing parts.

They havent fallen off yet.


the grease cap is just the size I needed,the hubs on my trailer are old and the ones these days are all a different size,but etrailer got the right size for me. thanks etrailer the caps are on my trailer.

I bought 4 of these caps for a tandem-axle trailer. Three fit perfectly. One was too loose to stay in place and required a thin strip of brass shim stock to make it secure. I don't think it's a fault of the caps, probably a variation in the opening in the hub. Perhaps one hub had been replaced by a previous owner and wasn't the same size as the other three. It would be good advice to measure all your hubs with a micrometer to avoid this issue. Notice that some of these caps only differ by a couple of thousands of an inch, but that difference can really affect the fit.


I was in the process of restoring a low speed agricultural axle and hub set that was probably from as far back as 1952. I found all of the bearings, races, and seals at local auto parts stores with the exception of the dust caps. I tried every auto parts vendor and trailer sales outlet known to man before finally finding the right size cap at E-Trailer. Their service was great. Shipping was cheap and prompt and the new caps fit like a glove.


excellent service, I received the caps sooner than expected.


Received the Grease/Dust?Water caps very fast. They were purchased to replace missing caps on one of my trailers so that the axle/wheel bearings would be protected from intrusion of dust and water and other contamination, reducing frequency of having to remove, clean, re-pack, replace and adjust the tension and reducing the concern of bearing failure due to contamination/premature wear.


It fit! This is an old Linco axle, 1-15/16" bore for grease cap.


Fast excellent service and delivery.


I built a fishing boat trailer out of "pieces" I had. The dust caps for the wheels I had were missing. It turned out that they were not a common size so after doing a search I was able to find just what I needed at I washed the preservative off them and gave them a coat of paint and my boat trailer was complete.


Looked all over for weeks for this Grease Cap. Found your website. You had the right size I need to complete my rebuild of an old boat trailer. The part fit perfectly.



Excellent - Absolute No Problems


This cap goes to an older cement mixer that was used once and the bearing cap came off and was lost. It was made in Canada and I was having a heck of a time finding a cap that would fit. Etrailer came through and hooked me up with the right part. An excellent bunch to work with. Thanks, guys.


Quality trailer product at a reasonable price. These grease caps were just what I was looking for. Thanks for the top notch service.

B. K.


The grease caps are still working like new on my trailer after a year. No problems.


I could not find what I needed locally but etrailer had it. Great price, very fast shipping, and an overall perfect experience. Very pleased!



Still in place and doing fine after a year.


I have an old axle with missing dust caps. I haven't a clue what vehicle or year it was from. I checked everywhere finding that they do not have measurements on most and the ones with measurements didn't include my size. changed that. Thank God they had everything needed to get the right dust caps with ease. Thank you for your site.


Great product, but had to return it because wasn't correct size measured on my end. Simply was guessing. However, please continue to put all the dimensions of your caps within the descriptions as was in this one. Certainly helped me make a decision from other competitors, even though I didn't get an accurate measurement prior to purchasing. Trying again with a 2nd purchase from etrailor. Simple and a great website, keep it up.


Rating: excellent. The boat trailer bearing races and bearing covers were shipped promptly and arrived quickly. I am happy with the responsive service from and recommend them to others.


This is to replace a bearing dust cap in an old cement mixer that was made in Canada. After a lot of research I was able to find one in Canada, however they would not export it to the USA. I was able to cross reference part numbers and came across this one at etrailer. Fits perfectly. Thanks.


This is a fine product and fit my application perfectly. But its just a dust cap. The real bright spot was talking with Gail, she was knowledgable and professional and made my small purchase seem important. I appreciate that, and will share my experience at every opportunity!


As I have come to expect E Trailer has delivered on time and in good condition. The Wheel Hubs fits perfectly and my trailer is on the road again.


They actually arrived dirty/greasy. They felt a little sticky. I cleaned them off, and they looked better. I wish I could say they work well, but they were too small. That was my fault. I needed something for my 1966 Aristocrat travel trailer. I guessed wrong. 4 stars because of the dirt.


Only issue is after 1 year the grease cap is completely covered in rust. (the trailer sits out in the weather)

  • Triton Grease Cap Size
    Measuring the inside diameter of the hub where the cap press fits into it is the best bet to get the right replacement grease caps. If you have access to a dial caliper, that would make the job that much easier. Measuring with a tape measure is difficult in this application. If you would like to try to find a part number and or manufacturer on your hub I would be happy to try to find the correct grease caps for your application. I am here to help let me know any information you can come up with.

  • Grease Cap Recommendation for Trailer Hub with 1.938 inch Bore
    For your hub that has a bore of 1.938 you would want the part # F001524 which has an outer diameter of 1.943 inches. This will fit your hub well.

  • Grease Cap Closest to 1.934 Diameter
    We have one option that may work for you as it is very close to 1.934 inches, but there isn't a cap available with that exact measurement. The cap with the closest diameter to that is the Fulton Grease Cap # F001524. This cap has a 1.943 inch outer diameter, and I don't see any reason why you wouldn't be able to make it fit considering the difference is just 0.009 inches. I have added a link below to a video review for you to check out as well of the Fulton Grease Cap # F001524.

  • Trailer Hub Dust Cap for 1.940 Hub Bore
    Are you sure you didn't order a cap for a 1.968 hub bore? We don't offer a cap for a 1.986 bore. The next size down would be for a 1.943 bore, part # F001524 which would be the correct fit for a 1.94 bore. Keep in mind, the dust caps are meant to be slightly oversize for a tight fit. You'll need to persuade it in with a hammer and a block of wood. I've linked to a product description video for the # F001524 dust cap.

  • Looking for 1.94 Inch Grease Cap and 35898 Grease Seal
    As far as a grease cap goes, I've found one that would work for you. The Fulton # F001524 has an OD of 1.943, which would make for a good compression fit in your hub bore. As far as the seals go, I didn't have much luck. I've looked through the grease seals we offer, and I'm not seeing anything that comes close to the dimensions you provided, I'm sorry to say. I even did a Google search of the 35898 reference number, and came up empty handed. There have been occasions where we've found...

  • 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.

  • Replacement Dust Cap for Motorcycle Trailer
    The first thing I would do is go ahead and measure to take the guess work out of the size. Using a digital caliper like the # PTW80157 you will need to measure the center of the hub where the grease cap will fit. I attached a diagram below showing where to measure. Since you will already be measuring, you can go ahead and measure how far out the axle stub extends to compare to height measurements on grease caps. You may also need to contact the manufacturer of the trailer to find or purchase...

  • 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.

  • Grease Caps With Outer Diameter Smaller Than 1.988 Inches
    We do have a grease caps that are smaller than those with a 1.988 outer diameter like the Grease Cap # F001518. In order to know the correct fit for certain you will need to use a digital caliper and take a measurement, but I'll go ahead and list out the smallest size grease caps we offer so you can try and match up the correct size. - 1.957" Outer Diameter: Grease Cap # TRAG-DC-196 - 1.943" Outer Diameter: Fulton Grease Cap # F001524 I have also added links below to video reviews for...

  • Which Grease Cap For Hub With 1.940" Bore
    For the 1.940" bore on your hubs you will need the Fulton Grease Cap - 1.943" Outer Diameter - 1-3/8" Tall - Drive In # F001524, but to determine the correct bearing assemblies you will need to do a little disassembly as I was unable to confirm which bearings you axle uses. You will need to remove one of your current hubs and look for the bearing numbers stamped in the face of each of the bearings as shown in the included picture of the # L44649. If your bearings are worn to the point...

  • Do You have Grease Caps for a 1.935 Bore Diameter Hub
    If there is any corrosion built up on the hub, it could be built up corrosion built up on the hub bore making the hole read smaller. Grease caps do not have to be very deep. They only have to go in far enough to fit snug and tight inside the hub bore. Many grease caps have a flange length of just a little over a 1/4 inch, and most are well under a 1/2 inch. If their is a bit of corrosion, try lightly scrubbing with some steel wool. After cleaning it up, a 1.943 cap like part # F001524...

  • Recommended Grease For Packing Bearings
    The Bearing Kit for 1 inch BT8 Spindle, part # BK1-100 does not come with the bearing grease included. We have the bearing grease available in several different size containers. I have attached a link to our product page for the bearing grease we have available you can check out. To make it easy to pack the bearings I recommend a LubriMatic Deluxe Bearing Packer, part # L70025. This has a fitting at the top that you can use a hand operated or power grease gun with.

  • Dust Cap with Over 1 Inch Depth with 1.98 Inch Diameter
    We don't have the "normal" grease caps that will fit your assembly, however, the 2" Lubed Dust Cap & Rubber Plug - 1.99" x 1.40" x 1.18" - Qty 1 # DC200L-DCRP will work just fine for you. Even though you don't have the zerk fitting on your spindle, these grease caps will work very well of you. The rubber cap will still keep dirt and debris out as well as moisture. Any of the Bearing Buddy protectors for your 1.98 like # BB1980A will also work for your application.
