Which Grease Seal for 5th Wheel Camper with Lippert 5200 lb Axle

Question:

I have a 5th wheel camper with Lippert 5200lb axles, and the documentation they provided me says that grease seal has an internal diameter of 2.25inch Will this kit work for that or would I need BK3-310? Thanks is advance for the information

Assuming that your hubs use the LM67048 outer and 25580 inner bearings, you will need the # BK3-300 which uses the 10-36 double lip grease seal with a 2.25 inch inside diameter. The BK3-310 uses a seal with a 2.125 inch inside diameter, which would not be compatible with your spindle.

If you wish, you can confirm this by using a digital caliper like # PTW80157 to measure the diameter of the spindle surface where the spindle rides, as shown in the diagram.
