Hey Allen! I went out to our warehouse and measured one of the # DX45BR hubs. Turns out our website was wrong. The pilot hole on the hub measured 2.33". So, it wasn't the 2.56" cap after all, but it isn't the 2.44" either. The 2.32" caps aren't exactly common, but we do carry one you can use:
- Zinc Plated Grease Cap - 2.333" Outer Diameter - 1.00" Tall - Drive In # TRDC-233
I actually grabbed one of the # TRDC-233 caps and made sure it fit in the # DX45BR hub. I didn't have a rubber mallet to drive it in, but I can assure you the 2.33" caps will fit. Glad you asked and we got to the bottom of it lol. Sorry for any confusion. I will get our website updated.
