Video Transcript for In-Depth Review of the Grease Cap, 2.44" OD Drive In with Plug

Today we're going to take at look at the trailer hub drive-in easy lube grease caps. These have a 2.44 overall diameter. This part is for a quantity of two. These grease caps are designed for trailers that have easy lube axles. If you notice it has a center rubber plug that pops right out. This plug is removed to access the grease zerk fitting that is usually on the end of an easy lube spindle on an easy lube axle.

It saves you. You don't have to take your whole hub off to grease the bearings. What you can do is with this on the end of the hub, you just pop the center rubber plug out. It gives you access to that zerk fitting, put your grease gun in there and pump the grease in. These are commonly used on 4,400 pound to 6,000 pound axles.

The caps are made of a 22 gauge steel construction. Again the plugs are rubber. These are a drive-in installation and they do have a corrosion resistant zinc plating to them. Again the quantity is for two of them. Two critical measurements on the center cap are going to be the flange diameter which is measured from here to here and the overall height from the bottom to the very top. On this cap our flange diameter is 2.44" and the overall height from the bottom to the top is right at 1.52".

When this is installed onto the hub, all you have to do is pop off your rubber plug to access the zerk fitting. When you're done greasing the bearings, just put the rubber plug right back in. That should do it for the review of the trailer hub drive-in easy lube grease caps with the 2.44 overall diameter and for a quantity of two.

Yes, unfortunately the grease caps do not typically come with individual labels. The easiest way to distinguish between them will be to measure the outer diameter to determine their sizes.



by:

Does what it’s meant to do. Delivery was fast and the product selection at e-trailer is second to none



by:

Everything came in good condition, and quickly. Thank you!

They seem to be good quality and work the way they should.

Great products. Fast delivery. Outstanding customer service. They go out of their way to ensure you get the product you are looking for.



by:

It's been a year since I purchased the bearing covers and there working great. Finish and rubber are holding up to the Florida sun.



by:

Replaced axles, new had EZ-Lube spindles and reused older drums and needed to retro fit with these Grease fitting access, dust caps. Worked perfectly

Good looking product, good tight fit. When installing the first time you'll need to file the burr off the edge and chamfer it slightly to get them started. They're still tight but you can persuade them with a wood block and hammer, without damage. They need to fit that tight and all four were uniform in fit, Thanks.

Have had no problem. Good heavy plating is still holding with no rust through.



by:

Works great! Exactly what I needed!



by:

Awesome delivery time along with great prices. Kept me informed on the status of my order.



by:

After ordering the 2.44 size, twice, from another website, that I thought would be faster. Both orders showed up measuring 2.46 and would not fit the trailer. The time I thought I would save, turned into two returns before ordering from etrailer. Which of course fit perfectly. Don't trust the many vendors that ship through [online vendor]. I should have gone to etrailer for the correct parts the first time.

  • Replacement Hub and Drum Assembly For Older Drum Marked HD-1206
    The HD-1206 number you found on your drum cross references to the Trailer Hub and Drum Assembly - 5,200-lb Axles - 6 on 5-1/2 # 8-201-5 which is a 12" x 2" drum with the 6 on 5-1/2" bolt pattern you mentioned but has wheel studs instead of holes for wheel bolts. The # 8-201-5 requires inner bearing # 25580, outer bearing # LM67048, grease seal # RG06-090, and grease cap # RG04-080 as these are not included. I included a video of the # 8-201-5 for you to take a look at.

  • Self Adjusting Brake Assemblies for 2009 Forest River Shockwave Toy Hauler
    For a set of self-adjusting brake assemblies that fit your 5,200 lb axles that have 12 x 2 inch drums you'd want the part # AKEBRK-7-SA and you'd be set.

  • Replacement Brakes and Hub Assemblies for Lippert 5,200 Pound Axle
    For your trailer the drums you need are # 8-201-5. They're designed to fit bearings # 25580 and # LM67048 with the 2-1/4 inch seal # GS-2250DL. For brakes I recommend # AKEBRK-7-SA. Both the left and right sides are included. They are side specific so you'll want to pay attention to the labels when installing. They're self-adjusting brakes so they'll need to be adjusted when you install them and then never again. The grease cap to fit the hubs is # RG04-080 if you have E-Z lube axles...

  • Looking For Replacement Seals For A 40 Year Old Triple Axle Trailer
    Hello Robert, sorry to hear the seals you got did not work. Being that this trailer is so old, I am not surprised to hear that finding replacement parts has been difficult. Looking thru all of the seals we carry, I do not find an exact match, but we have one seal that is quite close. The closest thing that I see is the Grease Seal # 10-40. This has an ID of 1.938" which should be perfect. The OD of this seal is 2.510" though, so it is a hair larger than what you measured. Since we don't...

  • Replacement E-Z Lube Grease Cap and Plug for 2005 Casita Travel Trailer
    In order to determine the correct E-Z Lube grease cap for your Dexter axle you are going to need to measure the center of the hub where the grease cap is going to fit. I recommend using digital calipers like the # PTW80157 in order to get an accurate measurement. Once you have your measurement you can match it up to the correct grease cap which comes with the plug. The # RG04-040 will fit a hub bore of 1.99 inches, the # RG04-080 will fit a hub bore of 2.44 inches, and the # RG04-120 will...

  • How and Where to Measure to Find a Replacement Grease Cap for a Trailer
    You would measure the outside diameter of a grease cap or the inner diameter of the hub bore where the grease cap installs. But the measurement has to be as accurate as possible so you would need to use dial or digital calipers to take the measurement. Another option is to get at least the outer bearing number stamped into the side of the bearing. You should be able to see it without removing the hub by wiping away the grease. I have included a link to our grease cap main page for you as well.

  • Replacement Trailer Bearings for Kodiak 6 Bolt Disc Brakes
    Kodiak disc brakes that have a 6 bolt pattern all use the same bearings and races. It is kit # BK3-100. The outer bearing is # 15123. The correct size grease cap for an EZ lube axle would be # RG04-080 which is a 2.44 inch diameter. The race will have the smallest of lips for you to catch a flat screwdriver or piece of pipe on so you can knock it out of the hub. I have included a link to a video and a link to an FAQ article that should help you.

  • How to Determine the Correct Replacement Grease Cap for a 2003 Bayliner 212
    The main difference between the grease caps, # RG04-080 and # DC250L-DCRP, is that the RG04-080 is for EZ lube axles and DC250L-DCRP is for standard axles. I have created a short video for you showing where to measure on your hub to determine the correct size grease cap. If you measure and determine that these caps will work for you, then I would recommend using the RG04-080 if you have EZ lube spindles with a grease zerk in the end of the spindle. Keep in mind that you will want your...

  • Replacement Hub and Drum Assembly for Dexter 008-219-04
    You are correct, the # 8-219-4UC3 matches your existing hub and drum assembly. I'm assuming you're referencing the difference in the grease cap when you say the grease is different. This has a standard grease cap, but you can use your existing E-Z lube grease caps in place of the caps that come with this assembly. If you want new ones you can use the # RG04-080. The grease cap and plug is the only difference between a regular and E-Z lube hub and drum assembly.

  • Recommended 2.5" E-Z Lube Grease Cap with Rubber Center Plug
    It sounds like you're looking for the E-Z Lube Grease Cap part # RG04-080 which is designed for a 2.44" hub bore. Please note, the grease cap that is designed for the hub bore is an exact figure that needs to be taken with a caliper but this size is standard for larger 5,200lb + axles and that is 2.44".

  • Availability of 7k Leaf Spring and 5 Spoke Utility Hub for Dexter 7.2k Axle
    We have leaf springs that will work for you, the PR6 is a 24-7/8 inch 7k rated double eye leaf spring. Then for a hanger kit that comes with equalizers, hangers and hardware you would want the part # APT5. The hub you mentioned is our part # 8-174-5UC3. This comes with bearings. For easy lube caps though you would need the part # RG04-080. I wish we had the axles you are looking for, but we only carry a select few axles at this time and none of them have the dimension/capacity that you...

All are shown on the linked page. All you need to do is measure your hub's inside bore diameter to choose the correct matching grease cap. Part # RG04-040 fits a hub bore of 1.99-inches. Part # RG04-080 fits a hub bore of 2.44-inches. Part # RG04-120 fits a hub bore of 2.72-inches. This is the size that fits the hub you...

  • Grease Cap Recommendation for a Trailer Hub
    In order to know what grease cap you would need you need to get an exact measurement with a dial or digital caliper. Tape measures aren't accurate enough since you are looking at the difference of .07 of an inch. If it measures 2.44 the part # RG04-080 would be the correct cap. Most likely this is what you have but I attached a page that has all of the caps we offer, select your outer diameter needed from the filters.

  • How to Determine Correct E-Z Lube Grease Cap
    To determine the correct E-Z Lube grease cap you are going to need to measure the center of the hub where the grease cap is going to fit (please see accompanying photo). The measurement will need to be very precise, so you are going to want to use a digital caliper such as # PTW80157. You will then just compare that to the available caps. Grease Cap # RG04-040 will fit a hub bore of 1.99 inches. Grease Cap # RG04-080 will fit a hub bore of 2.44 inches. Grease Cap # RG04-120 will fit...

If you are wanting to upgrade to Bearing Buddys (which would require you to remove the grease zerk on your spindle) we have these both in Chrome # BB2441 and Stainless Steel # BB2441SS.

  • Grease Seals and Dust Caps for AL-KO Trailer Hubs with 25580 and 15123 Bearings
    The most grease seal associated with hubs that use the bearings you have specified is # GS-2250DL for 1 seal or # RG06-070 for a pair. For a grease cap you will likely need a 2.44 inch cap as that is the size associated with the hubs that use the bearings you mentioned. If the spindle has a grease fitting at the end use # RG04-080. If the spindles do not have grease fittings use # RG04-060.

  • Grease Cap for E-Z Lube Axle
    Since you mentioned 2-3/8 inches (2.375) as the inside diameter it is likely that you need the Grease Caps # RG04-080 which has an outside diameter of 2.441 inches. The best way to find exactly what cap you need is by measuring your hub bore with a digital caliper, as that will tell you the diameter of the cap that will fit. I have added a link to a video review of this cap for you to take a look at.

If you have 7,000 lbs or 8,000 lbs axles, then you will need part # 21-43-1 and # DC-RP if you have EZ Lube spindles (grease zerk on the end) or you can use part # RG04-100 if you have standard spindles. If you have 5,200 lbs or 6,000 lbs axles, then you will want part # RG04-080 if you have EZ Lube spindles or part # RG04-060 if you have standard spindles.
