Dexter Grease Cap K71-314-04, 1.99 Inch OD, Fits 7 Inch and 10 Inch Trailer Hubs, Pair

The Dexter K71-314-04 grease cap presses into the end of a trailer hub to seal the bearing cavity, keeping grease in and water, dirt, and road debris out. It is sized with a 1.99 inch outside diameter and is engineered to fit Dexter 7 inch hubs as well as 10 inch x 1-1/2 inch and 10 inch x 2-1/4 inch hubs. This cap is sold as a pair, so a single purchase covers both hub ends on one axle.

Keeping the grease cap intact and properly seated is a basic maintenance item for trailer hub and bearing service: a cracked, corroded, or missing cap allows grease to leak out and lets water into the bearing race, which accelerates bearing wear and can lead to a failed wheel bearing on the road. Because it presses in without tools, the K71-314-04 is a straightforward replacement during routine bearing repacking or hub service.

Frequently Asked Questions

What hubs does the Dexter K71-314-04 grease cap fit? The K71-314-04 fits Dexter 7 inch hubs and 10 inch x 1-1/2 inch and 10 inch x 2-1/4 inch hubs, with a 1.99 inch outside diameter.

How many caps come in this listing? The Dexter K71-314-04 is sold as a pair, so you get two grease caps, enough for both hub ends on one axle.

What is the outside diameter of this grease cap? 1.99 inches is the outside diameter of the K71-314-04 grease cap, sized to press into 7 inch and 10 inch Dexter hubs.

Is this a grease cap or a dust cap? It is a grease cap, designed to press into the outer end of the hub and seal the bearing cavity, keeping grease in and contaminants out.

How much does the K71-314-04 grease cap weigh? Each package of the Dexter K71-314-04 weighs 0.21 pounds.

How is this grease cap installed? The K71-314-04 is a press-fit cap that seats into the end bore of the trailer hub, typically installed by hand or gently tapped in during bearing repacking or hub service; no fasteners are required.

Will this cap fit a 10 inch x 2-1/4 inch hub with a 4.4K rating and 12 inch hubs? No. The larger 10 inch x 2-1/4 inch (4.4K), 12 inch x 2 inch, 5 spoke, and 6 bolt hubs use Dexter's K71-316-00 grease cap, which has a 2.45 inch outside diameter, not the K71-314-04.

Why does a trailer hub need a grease cap? A grease cap like the K71-314-04 seals the outer end of the hub bearing cavity, retaining lubricant and blocking water and road debris; a damaged or missing cap can lead to grease loss and premature bearing failure.

Is the K71-314-04 a genuine Dexter part? Yes, K71-314-04 is the Dexter part number for this 1.99 inch outside diameter grease cap.

What size hub does this cap not fit? The K71-314-04, with its 1.99 inch OD, does not fit Dexter's larger 2.45 inch OD hubs (10 inch x 2-1/4 inch 4.4K, 12 inch x 2 inch, 5 spoke and 6 bolt); those use the K71-316-00 cap instead.

What comes in the package? The Dexter K71-314-04 listing includes a pair of grease caps (two caps total).
