Replacement Trailer Seal for a 2000 Trailstar Boat Trailer Measuring 2.327 Outer and 1.676 Inner

Question:

I am working on a 2000 model trailstar boat trailer. The measurement on the hub where the seal presses into has a measurement of 2.327 using my telescoping gauges, and micrometer. Using my calipers on the spindle where the seal sets is 1.676. Will seal no. 168233 work for this? It seams like it would be a tight press, and i am not sure that it would seal on the shaft.

Given that we are talking about thousandths of an inch difference, it is very likely that grease seal, # 168233, is the correct seal for you. To be certain, you can find the inner and outer bearing numbers stamped into the metal of the bearings. That way I can determine all of the correct parts for your boat trailer.

You can also look at the seal you have for a tiny, nearly unreadable part number on the black rubber part of the seal somewhere. It is very tough to read. But if you see any of the following numbers, then this seal is a correct replacement:

168233TB
473317/47140
AF7616EO/AD2527EO
16657/16659
