Will the Americana Trailer Wheel Center Cap # AM90098 Fit a Boat Trailer With Oil Bath Hubs


Needing to replace a couple of center caps on my triton boat trailer. Do these center caps work with the oil bath hubs? Does the end pop out? Thanks!


Expert Reply:

The Americana Trailer Wheel Center Cap, part # AM90098, has the removable top plug that can be removed for easy access to an EZ lube trailer spindle. The EZ lube axle has a zerk fitting on the end of the spindle for filling the hub with grease. This center cap will fit 15 inch wheels with a 5- lug bolt pattern and a pilot hole diameter of 3.19 inches.

Most axles that use an oil bath hub are larger axles and with oil bath hubs you will usually want to see the center cap that will show the oil level inside the hub.

If your boat trailer has oil bath hubs and your wheel is a 5-lug bolt pattern with a pilot hole diameter of 3.19 inches, I would see if this center cap matches the center caps you have now to tell if they will fit your oil bath hubs.
