Finding Correct Grease Seals for Boat Trailer for 23 Foot Bayliner  


I need to replace bearings on a trailer. One side of my boat trailer failed so I pulled the other side wheel to obtain the correct part numbers. The bearings and races match up but I cant find a corresponding seal that matches any of the numbers I find on the seal. Ive inspected the seal with a magnifying glass to make sure I didnt miss anything. The alphanumerics found on the rubber part of the seal are as follows: TTO E906 SB 232 175 43 TAIWAN CSL TULSA As I said, Im not able to find any other numbers on the bearing seal. Any help would be appreciated. General info, it is for the rear wheels of a dual axle trailer pulling a 1988 Bayliner 23 foot boat. I just assume the trailer came with the boat but have no way of knowing. Dont know if that last bit of info makes a difference or not. Let me know if the bearing seal in the BK 2-100 would be a correct replacement. If so Ill buy 2. Thanks


Helpful Expert Reply:

The numbers you provided didn't match up with any seals we offer.

To find the correct seal, you'll need to use a digital caliper and measure the inside diameter of the hub bore where the seal would sit. To find the needed inner diameter, measure the diameter of the spindle that the grease seal rides against (see photo I've provided.) If you'd obtain these measurements, and shoot them to me in a reply, I'd be happy to find come compatible seals for you.
