Video Transcript for TruRyde E-Z Lube Grease Cap Plug Review

Speaker 1: Today, we're going to be taking a look at the TruRyde rubber lube plug that fits the 1.18-inch lubed dust cap. It's sold as a quantity of one. Part number is DC-RP. For the quantity of two, part number is RG04-010. These dust plugs are very inexpensive, but very critical component to any trailer hub system with the E-Z Lube axles. These, you can see we've got one missing here.

Our design to cap this off preventing water, dirt, and debris from getting inside the hub where it can cause major problems. In your hub you've got bearings that are going to ride on races. You can see the grease in there that keeps those working properly. Once dirt and debris gets in there, it starts wearing on those. The life of our bearings is going to be greatly reduced.

At the extreme side of that, it could cost us an entire axle. It's a very and simple thing to install.You can see the lip all the way around the outside here. That's going to go right inside the metal ring. Place them in. Push it in all the way around and that's going to be sealed up at that point.

We'll not have any issues with moisture or debris getting in there, causing us headaches. Now here's another great example of a dust cap that needs replaced. You can see it's kind of deteriorating here. We can start to see cracks in it. It doesn't fit properly all the way around.

That allows an area for the moisture to go right in. To remove it, it's quite simple. You just pop it out. Grab our new one and we'll put it in place. That'll complete our look at the TruRyde grease cap plug for the E-Z Lube grease caps.

This is the second time I have ordered items from etrailer and am extremely pleased with the way sales staff assisted me then and now. The sales staff member assisting me with the order of grease cap plugs was Mariah A. She was great. I received my order as ordered on November 2nd,2020 and did the simple install right away on my ATV trailer. I will definitely do business with etrailer again. Thanks again Mariah A.

The grease plugs are performing as expected.I am very satisfied with this product.

Appreciate the prompt service but I guess I messed up on my order. I got two bearings that were the same size. My hub has a bigger inner bearing and seal.


Comments
You will need to know both the inner and outer bearing numbers. These numbers can be found stamped on the bearings themselves or you can use a digital caliper such as item # PTW80157
4" Carbon Fiber Digital Caliper
$10.95
to measure your spindle to the thousandths of an inch at the seal, inner bearing and outer bearing.

I tried this product for an aviation application. I own a DHC-2 Beaver aircraft that has a tail wheel axle that is 1.125 inch ID. I wanted an end cap that was removable because the axle tube is used to steer the aircraft with a hand held bar during some ground movement. So far the rubber cap seems to work. It has remained on during several flights. It is easy to remove and insert. The only problem may occur if the cap mounting area of the axle become oily or greasy which may allow the cap to slip off. It seems to need a friction fit to stay on.


Comments
Same as described above.

I bought these dust caps, the matching rubber ends, along with the etrailer driver tool. (290-991 for the size caps I have.) I was having issues with the Kodiak disc brake/Hub combo opening being a tad smaller and bent a couple of caps putting on with a dead blow rubber mallet. So ordered some new caps and the etrailer driver tool. Having the driver tool to keep these going straight and from warping (It fits pretty snug around the cap.) and really helped out. I also put a little grease around the edge of the rubber seals to help ward off water. What I like about e-trailer is they have about everything you need for trailers at one place. Their folks are friendly, knowledgeable, and helpful when you call.

Still working great!

I bought a used utility trailer with no manual so I was in the dark as to what I needed to replace the failing dust covers after regreasing the hubs. The information on the etrailer website helped me confirm what I needed, the parts were in stock, and they were delivered promptly. I’ll return when I have future trailer part needs.



- RG04-010
by:

These are the caps that get removed to pump grease into an Ultra-lube hub. Perfect fit on my trailer with AL-KO 8490 axles and 10x2.25 brakes. Very nice price for a product that can be hard to find locally. I can't prove it, but my research suggests these cross reference to: + 85-10 + AL KO #568067 + Hayes #09213611 + TruRyde RG01-010 + Dexter 085-001-00

These grease cap plugs fit perfectly. My bearing are now protected.

I have ordered multiple times from etrailer. The orders have arrived earlier than stated and with everything complete as ordered. Great prices and service.



- RG04-010
by:

These grease caps had only light cracking after one year of service. Most caps that I have used in the past would be cracked and leaking after one season of boating, some wouldn’t even make a full season and would require a replacement. Rubber rot seems to be a serious issue with all of these plugs, but these held up the best of any I’ve used. After greasing the bearings I always replace the caps with new fresh caps yearly, the cost is minimal compared to the damage that may happen if not properly cared for.



- RG04-010
by:

I was surprised. I had resigned myself to a less than ideal fit from an off-brand product. But these plugs actually fit tighter than the original Dexter plugs that came on my axles. Will they last? I don't know. I'll check back in a couple of years.



- RG04-010

I needed these to replace the original caps on my trailer that were starting to leak. They fit well and should last as long as the others.

Finding the product and placing the order was super simple. Delivery was unexpectedly quick. I had my parts in hand within 2 days of placing my order. I've purchased from etrailer before and will most certainly again in the future.

Great products, and available! Fast and efficient customer service!

by:

I am ecstatic. These are direct OEM replacements. I was left questioning similar products listed on Amazon in regards to size and durometer rating. 5 stars for me!



- RG04-010
by:

I cannot honestly give these a good rating as I cleaned up my old ones and will be putting them back into service. While the rubber on these is soft and pliable compared to the original equipment, the tolerances are all wrong to be able to get a snug seal. The groove in the seal that fits over the sheet metal cap is too wide in the first place, something like 1/16" with the metal being probably half that. Second thing is the hole is slightly larger then the center of the rubber when it is installed meaning this plug does not make a tight seal, my old stiff ones make a tighter seal and will be reused. Also, the part of the rubber plug in the inside has a much smaller lip the catch the metal then the old ones which probably makes it easier to get off and put back on but also means it can fall off much easier as the tolerances are such that it moves around and does not seal tight. In my experience I cannot recommend these.


Comments
Nothing has changed, my opinion is still the same and they still sit in a parts bin unused solely to be used as backup in case of emergency.

    The Grease Cap Plug for E-Z Lube Grease Caps - Qty 2 # RG04-010 is designed to fit in E-Z Lube axle caps that have a 1.18" diameter opening. If you don't have an E-Z Lube it's possible that if you're measuring the outside dimensions of your grease cap that potentially the inner diameter of your grease cap is also 1.18" diameter. A similar plug is the Rubber Lube Plug - Fits 1.18" Lubed Dust Cap - Qty 1 # DC-RP, which is designed for regular axle grease gaps and is also 1.18". Both of these...

    After looking at some photos of the Performance boat trailers it looks like you likely have 1/2" wheel bolts.

    If you are looking for a grease cap PLUG with the TRP stamped on it chances are the Grease Cap Plug for E-Z Lube Grease Caps # RG04-010 would work for you, but to be certain you will want to measure the diameter of the grease cap hole. If it is 1.18 inches across then the # RG04-010 would work for you. If you only needed one cap you would want the # DC-RP.

    Yes the lug nuts you mentioned part # 12CLN-L are a fit to the wheel studs part # 7-262. The Lynx trailer wheel part # LHSL311B has a 4.25 inch pilot diameter so the wheel center cap part # 425EZ would fit.

    You identified the correct grease cap, part # RG04-040. This is sold as a set of two caps. If you ever need replacement rubber plugs we also offer these as a set of two, part # RG04-010. Since your trailer uses EZ-Lube zerk fittings on the spindles you will be better off with a grease cap that has a removable plug. This will enable you to get quick access to the grease fitting without having to take off the grease caps. If you want to simplify installation of the grease caps you might...

  • Replacement Grease Caps for a Trailer Hub with 2-1/16 Inch Hub Bore
    Instead of measuring the grease cap, measure the hub bore where the grease cap fits. You will need the most accurate measurement as possible so use dial calipers. You may find that you have a 2.047 inch bore so you could use bearing protectors like # BB2047SS. Or it could slightly larger, 2.080 like # BB2080. These are the 2 most likely sizes if you are coming up with 2-1/16 inches but measuring the hub bore with dial calipers would be the way to go.
