Replacement 3 Inch Wide Wobble Roller for a 1996 Tracker and Trailstar Boat Trailer

Question:

Hi, I have a Tracker Trailstar trailer. Year is about 1996. Looking for wobble rollers. They appear to be 4inch in diameter, 3inch wide with an I.D. of 1.140. The I.D. of the roller then has a two piece nylon sleeve with Yates embossed on it that takes it down to .695. Then a 5/8inch bolt is used to secure to bracket. The markings on my old roller just have Yates, 343R on the outer edge, with 19Y embossed in the recessed part of the roller, which I assume is a casting number. From what I can find on your site a YR343-5P is the closest I can find.

You are correct. Wobble roller # YR343R-5P is indeed the 343R roller. But it has a diameter of 4-3/8 inches and a width of 3 inches. The roller fits a 5/8 inch diameter shaft or bolt. It is possible that over time your existing roller wore down some so the diameter is not exactly the same as a new one.
