  • Hub Bath Idler Hub Replacement for 7K Axle
    The best solution we have for your application is the Dexter Trailer Hub # 008-399-93 which is typically used for 8K axles but it comes with all of the parts needed for an oil bath hub, save the oil which you can get with part # XLPROLUBE. The bearings will match up to your spindle and the seal has a 2.25" inner diameter which is pretty typical for a 7K spindle. The biggest difference you'll see is the 5/8" wheel bolt as opposed to 9/16" bolts like what your 7K hub will have. This means...

  • Dexter 8,000 Pound Axle Idler Hubs with 5/8 Studs for Kodiak Disc Brake Kit K2R858DD
    If your current hubs use grease and are not oil bath then you will need idler hub # 008-399-92 to go with slip-on rotor # K71-635-2. But if it is an oil bath set up you will need # 008-399-93. In either case the hubs have the 8 on 6-1/2 bolt circle, 5/8 inch studs, are fit Dexter 8,000 pound axles.

  • Oil Bath Hub Installation and Operation for 8,000 lbs Dual Axles
    Oil bath hubs like the Dexter Trailer Idler Hub Assembly # 008-399-93 for 8K axles or the hub/drum version # 8-285-10UC3-A simply soak the bearings in oil to keep them lubricated. Dexter bought out AL-KO years ago after they partnered for a long time. The center cap screws on as you stated and has an o-ring to prevent leaking. The cap just needs to be secure so you don't overtighten and damage the threads causing leakage. The center plug allows you to keep the cap in place and add oil...

  • Recommended Trailer Brake Conversion to Oil Bath Disc Brakes
    To convert your 7K #42 axle from drum brakes to hydraulic disk brakes with wet bearings I recommend the HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-T1. The 10-10 Grease or Oil Double-Lip Seals - Qty 2 # RG06-090 will work with the Oil Cap Kit - 21-40 # RG04-260. This is the best option for your conversion.

  • Can Dexter Trailer Hub # 008-399-93 Be Used with Drum Brakes
    The Dexter Trailer Hub # 008-399-93 that you referenced can only be used for disc brakes with the addition of an appropriately rated rotor assembly like # K71-635-00. For electric or hydraulic drum brakes a hub-and-drum assembly is needed instead. For an oil bath 8,000 pound hub-and-drum assembly that will fit the same spindle as the above option the Dexter # 8-285-10UC3-A will work perfectly. For the corresponding brake assemblies I recommend the Dexter Self-Adjusting # 23-450-451 for...

  • Can Standard Lug Nuts be Used With the Taskmaster TA69VR?
    The Taskmaster Provider 215/75R17.5 Radial Tire w/ 17-1/2" Solid Center Wheel - Offset - 8 on 6-1/2 - LR H # TA69VR is designed to be used with and requires the use of flange nuts instead of the standard conical style lug nuts. Typically an 8,000 pound axle will use 5/8"-18 studs as the 1/2"-20 stud will usually denote a hub/drum that will be used on up to a 7,000 pound axle. With that being said, I recommend upgrading your hub/drum to go with this tire and wheel set-up. If you have brakes...
