Video Transcript for Hands-On with the Oil Cap Kit

Today we're going to take a look at the oil cap kit for 6,000 pound and 7,000 pound Dexter axles. This oil cap is a screw-in plastic cap. It's a clear cap so you can see the oil level through it. It is designed to fit 6,000 pound and 7,000 pound Dexter axles with oil bath hub and drums. The outer diameter of this cap is measured 2.563 inches. The kit does come with the oil cap itself, comes with the rubber plug that you take this off to fill with oil and put it back on to seal it, and it comes, as you can see here, with the rubber O-ring on it to help seal it when you screw it in to the hub assembly.

That should do it for the review on the oil cap kit for 6,000 pound and 7,000 pound Dexter axles.

  • Replacement Sight Glasses Or Bearing Buddies For A 2003 Boatmate Trailer
    Hello Steve, I can certainly point you in the right direction. Unfortunately, we do not have a way to look up a serial number of a trailer in order to know what sight glasses or bearing buddies you would need. Only the manufacturer of the trailer would be able to provide that info. Do you happen to know the weight capacity of each axle? That will help to narrow it down a lot. Or if you were to take one of the current oil caps and measure the OD of the threaded portion, that would tell us...

  • Replacement Caps for Oil Bath Hub With 2-3/4 Inch Diameter at the Threads
    We do offer a grease cap for an oil bath hub that has a 2-7/8 inch diameter at the threads, part # RG04-230, however the total height of the cap is 1-3/4 inches. This is the closest thing we offer to the oil bath cap you referenced.

  • Oil Bath Hub Cap for Mastercraft Boat Trailer
    The oil caps we offer are for much higher capacity axles than what you have based on the bolt pattern of your trailer wheel. That said there's a chance the part # RG04-260 would fit but this has an outer diameter of 2.563 inches. You'd have to verify that first. Or if you have something different let me know and I'll see what size we have that could fit.

  • Replacement Wheel Studs for AL-KO Hayes 09080587 10K Axle Hub
    From my research, it looks like your 10K Axle AL-KO Hayes hub #09080587 uses six 5/8 x 2-3/4 inch wheel studs for single and flat face wheels. The correct replacement is our Trailer Hub Wheel Stud, Screw-In # 7-232. Below are some other direct replacement parts for this hub assembly: Outer Bearing # 28580 Outer Race # 28521 Inner Bearing # 25580 Inner Race # 25520 Oil Cap Kit # K71-859-00

  • Replacement Plastic Cap and Seal for 8K EZ Lube Axle
    The Replacement Grease Cap for Kodiak 8,000-lb Disc Brake Kits # KPCAP is designed to fit a 2.25 inch spindle and has a thread outer diameter of 2-7/8 inch by 12 thread. We also have the Oil Cap, Plug and O-Ring for Dexter 7-9K Trailer Axles # RG04-230 with the same dimensions. We don't have the Viton O-ring outside of the cap replacement kit. Either of these will work on the EZ Lube axles.

  • 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.
