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.

  • 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...

  • Grease Cap and Dust Cap Needed for Trailer Bearings
    We definitely carry those! For those parts, you need 2x of the # RG04-080 and 1 of the # DC250L-DCRP. I went ahead and attached helpful demo videos of these products for your convenience.

  • 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.

  • Dust Cap Recommendation for Ranger Trail Boat Trailer 9606087
    You will want to use a dial caliper or micrometer 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 wish there was a different way but this is the only reliable method. 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 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.

  • 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".

  • 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...

  • 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...

  • Converting From Disc Brakes to Electric Brakes on 1977 Airstream Sovereign 31
    In order to verify if this is the correct hub and drum assembly you will need to check the bearing numbers. If the numbers are too worn, you will need to measure using a digital caliper like the # PTW80157. I have attached a photo of where you need to measure on your spindle. We will assume you have this information since you already removed your hub and drum. The Dexter Trailer Hub and Drum Assembly # 8-201-5 is for 5,200 lbs axles and has a 6 on 5-1/2 bolt pattern. This uses a # 25580...

  • Replacing Bearings, Races, Seals and Dust Caps on a 5th Wheel Trailer
    Yes, the Dexter axle part number 4003321 you referenced works with the hub and drum assembly part # 8-201-5UC3-EZ which is a 5,200 pound axle. The hub pattern is 6 on 5-1/2. The parts you will need are inner bearing # 25580 (4) and outer bearing # LM67048 (4). You will need seals # RG06-090 and dust cap # RG04-080. The seal and dust cap will come as a pair. I have included a FAQ and multiple videos for you too.

  • 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...

  • Grease Cap for Dexter 8-248 Hub Assembly
    If you have trailer hub assembly 8-248-50UC1-EZ the correct replacement grease cap is # DC200L-DCRP. This cap is for E-Z Lube spindles and measures 1.99" x 1.40" x 1.18"; I've added a link to a video review of the cap for you to take a look at as well.

  • 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.

  • Replacement Bearing Cover Options for Bri-Mar Dump Trailer
    You will need one of two sizes depending on the axle capacity of your Bri-Mar dump trailer. 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.

  • Replacement Dust Cap for Hub with 2.312 Inch Opening
    I have a solution for you, but it's unlikely that you're going to be able to use the # RG04-080 because of the difference in size. If you don't have EZ lube axles, you could use the Fulton Grease Cap # F001601 which has a diameter of 2.33" and would be a much closer fit for your trailer-in fact, if you look through some of the reviews there are some Ranger boat owners who've said this was a match for their trailer. This is a zinc plated steel grease cap that will provide good corrosion...

    The correct grease/dust cap size for your Kodiak Disc Brake Kit # K2HR526D is 2.44". For EZ Lube grease caps with this dimension we have part # RG04-080 which comes in a quantity of 2. 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. The advantage of the Bearing Buddys over the EZ Lube is that the Bearing Buddys give you an easy way to add grease and...

  • Replacement Grease Cap and Wheel Studs for a RV Trailer Hub with ALKO Electric Brakes
    The grease cap part number that you referenced cross references to a drive in cap with a 2.44 inch outside diameter. If you have a standard cap then the Grease Cap, 2.44 inch OD Drive In, item # RG04-060, is the correct part. If you have a grease fitting in the end of the spindle then the Grease Cap, 2.44 inch OD Drive In with Plug, item # RG04-080, would be the correct part. These parts are correct only if the 092101 part you mentioned is correct. The correct inner and outer bearing part...

  • 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.
