If your hub bore is 2.25" in diameter like the # KPCAP then the closest Bearing Buddy Grease Caps would be the # BB2240, which measure 2.24", but this is commonly found to be compatible with Dexter 5200-lbs axles with an outer race 1729 in the hubs. I'm not quite sure this is what you're looking for so you'd want to measure your hub bore using a digital calipers like the # PTW80157 to make sure that you're getting the right ones. Those # BB2240 are push in Bearing Buddies so you'd also want to make sure you don't have a threaded bore- which would likely be the case if you've got an oil bath hub.

If you are certain you've got a 2.25" hub bore and it's threaded, you're not going to be able to make those Bearing Buddies work, but let me know what you find and I can see if we can come up with an alternate solution to let you switch to greased hubs instead of an oil bath.

For your Dexter 5,200 lb hub the Bearing Buddy part #BB2441SS is the correct fit. Installing it is pretty easy. Using a flat board and a mallet you'd lightly hammer it into place.
