Grease Cap and and Double Lip Seal for Trailer Hub and Drum Assembly # 84546UC3
For a single grease cap for hub # 84546UC3 you can use # F001518. The grease cap being slightly larger in diameter than the hub bore is normal to create a tight fit. Grease seal # 58846 is a single lip. Single lip seals do not keep grease in as well as double lip seals. For double lip you would use # RG06-050 for a pair.

How to Determine the Axle Capacity of Axles on a 1977 Dilly Tandem Axle Trailer
I can tell you with relatively high accuracy what the axle capacities probably are based on the inner and out bearing numbers. If you can tell me what the numbers are on the bearings are by pulling a hub I can give you a more definitive answer. A 5 on 4-1/2 hub can be found on everything from 2,000 to 3,500 pound axles so know the bearing numbers is important. I have included a link to a video that will help you with this project.

Replacement Wheels for 1988 Jayco J-750 with Proper Pilot Diameter
Since your existing wheels use lug bolts instead of lug nuts, we refer to them a hub-centric rather than lug centric. A lug centric wheel is supported the wheel studs, which means that the studs not only function to keep the wheels in place, but they also bear the vertical load of the trailer. In contrast, with a hub-centric wheel, the lug bolts hold the wheel in place, but the vertical load of the trailer is primarily supported by the portion of the hub that passes through the pilot hole of

How to Select New Brakes and Hubs for a Load Rite Boat Trailer
The 2,600 lb axles on your Load Rite boat trailer are likely de-rated 3,500 lb axles, so you should have no problem using 3,500 lb brakes and drums. The important factor to consider in this situation is that the brakes match the brake mounting flange on your axle and that the hubs/drums match your spindles. Almost all 3,500 lb brake assemblies require a 4-bolt brake mounting flange. The bolt holes on the brake mounting flange should be 2-7/8 inches apart on center. If your brake mounting fla

Will Trailer Hub and Drum # 84546UC3-EZ Fit an ALKO 3500 Pound Axle
I read through the other question you sent and I can clear some things up for you. First, the ALKO axle brake mounting flanges have a different bolt pattern than do Dexter or similar assemblies when you go up to a 12 inch brake assembly and that is why they will not fit ALKO axles. The top mounting holes on an ALKO mounting flange are wider than they are on a Dexter. But on a 10x2-1/4 inch brake assembly the 4 bolt pattern should be the same. So you can use other 10x2-1/4 inch assemblies on

How to Correct for Extreme Stress and Bearing Damage on 5200-Lb Torsion Axle on Tandem Trailer
If your axle castle nuts are backing off and shearing the cotter pin then this extreme force could be coming from one or more possible causes. I suggest you check your rear axle tire treads for signs of uneven wear. If you notice more wear on the inside edges of the tires this could indicate any of several possible root causes, an overloaded axle, damaged axle or bent spindles. Any one of these conditions could result in wheel misalignment. This condition could in turn lead to excessive heat

Can Brakes be Installed on Only One of the Axles of a Tandem Axle Trailer
Brakes can be installed on only one axle of a tandem axle trailer, however you should first check your state laws to see how many brakes are required for the gross vehicle weight rating (GVWR) of your tandem axle trailer. Some states require a specific number of brakes based on the maximum weight capacity of a trailer. If you are able to install brakes on only one axle, I recommend installing them on the front axle. The front axle will bear more weight than the rear axle (see photo) and in b

Can a Trailer Wheel have a Larger Center Hole than the Hub
There are 2 different ways that a wheel secures to a hub. Either it secures to the hub using lug nuts or it secures to the wheel with wheel bolts. Wheels that attach using lug nuts can have a larger pilot hole because the wheel is centered using the lug nuts. The pilot hole cannot be smaller on the wheel though. If the wheel secures using lug bolts then it has to be an exact fit because the wheel centers on the hub itself and the bolts just hold it in place. If you do have this type of whe

How to Determine the Weight Capacity of a Dexter Hub and Axle
Based on your bearing dimensions, I think Dexter meant to say that the replacement hub for you is a 6-lug hub rated for a 5,200 lb axle, not that it is a 5,200 lb hub. Your axle is likely rated for 5,200 lbs, especially since the axle tubing has a 3-1/2 inch diameter. I have not heard of a hub with a 6-lug bolt pattern for a 10,000 lb axle or a 10,000 lb axle with 3-1/2 inch diameter tubing. The Dexter Hub Assembly, # 42655UC1, that you referenced is likely going to be the hub that you need.

Capacity of # 42655UC1 Trailer Hub
The hub you mentioned, # 42655UC1 is compatible with a 6,000 lb capacity axle. Each hub is rated at 3,000 lb max, or 6,000 lb per axle. For a tandem axle set-up, the hubs would provide a 12,000 lb capacity. Assuming that your existing hub uses a # 25580 inner bearing, and a # 15123 outer bearing, this would be the proper replacement. Four hubs would equal a 12,000 lb capacity for a tandem axle trailer. These hubs are compatible with grease seals that use either a 2.25 (# 42385) or a 2.125

Compatibility of Automotive Wheel with 9/16 Inch Lug Holes with Trailer Hub Using 1/2 Inch Studs
The taper of the lug nuts should take up the .062 difference between the 9/16 inch hole and the 1/2 inch wheel stud, allowing the lug nuts to tighten with no problem. In most cases you can use an automotive wheel on a trailer, but you will need to make sure that the wheels have the proper capacity for the load you will be carrying.

Comparing Leaf Spring Axles, Torsion Axles, Dexter and Hayes/AL-KO
I personally would not have any reservations about using a torsion axle. Dexter is a leader in the industry but Hayes/AL-KO are quality as well. It seems to be easier to get parts for Dexter axles and they tend to cost less. On a torsion axle you will want to be cautious not to overload it (of course this goes with leaf spring axles too). The suspension components on leaf spring axles are easier to replace as well but a torsion axle is going to give you good performance provided you keep up w

New Trailer Wheel Center Pilot Hole is Larger than Old Wheel Center Pilot Hole
On some wheel and hubs the center pilot hole has to be the exact size of outer hub bore. This is because the wheels are hub centric meaning they center on the hub rather than the lug holes. Hub centric wheels and hubs will use wheel bolts and not lug nuts. If the wheel centers on the hub using lug nuts (the studs are mounted in the hub) then having a larger pilot hole on the wheel is fine.

How Much Play Should Be Allowed for a Hub and Bearings on Hub and Rotor # KHR138XL10
As far as how much play there should be in a hub once installed, normally when you mount a hub and tighten down the spindle nut you need to allow for 0.001 to 0.007 inches of end play for the bearings. This can be achieved by tightening the spindle nut while turning the hub. Once there is a slight bind on the bearing you know the parts are seated correctly.

How To Measure the Bolt Pattern on a 15 Inch Wheel With 5 Lug Bolt Holes
When measuring to determine the bolt pattern of a wheel with an odd number of lugs, like a 5 lug wheel, you are basically measuring the diameter of a circle that would run through the center of each lug hole. If you are measuring the wheel the easiest way is to measure the distance between the center of one lug hole to the center of the lug hole adjacent to it, then look on the chart and if that measurement is 2-5/8 inches the bolt pattern is 5 on 4-1/2. If it measures 3 inches the bolt patte

Does Hub/ Drum Need to Be Replaced if Armature Surface is Grooved
Because the face of the magnet rides against the armature surface (inside surface) of the brake drum, any grooves that had previously been worn into the armature surface will cause the magnet to wear unevenly. For optimal braking performance, you want maximum contact between the face of the magnet and the armature surface of the brake drum. If the drum itself got too hot, you might see some blue discoloration on the armature surface. In extreme cases, the armature surface can warp. It might b
