Bearing Kit Options For Tracker Pontoon Boat Trailer With Bearing L44649 & Dexter 010-019 Seal


Can you tell me what set of bearings I need? The only numbers readable are the race which is an RTK L44610 or the rubber seal, one side has a Dexter 010-019-00 and the other side has a National 473336. These are off of a Tracker Track Star pontoon trailer. Thank you

Based on what you gave me I can narrow it down to one of two bearing kits for your Tracker boat trailer. Since you mentioned L44610 that means one of the bearings is L44649, and when combined with the Dexter 010-019-00 grease seal, that leaves two options. One is for a 3,500 lb axle and the other is for a 2,200 lb axle, so you can check and see what your axle rating is, which will help decide:

- 2,200 lb Axle: Bearing Kit, L44649 Inner/Outer Bearings, 10-60 Seal # BK1-150

- 3,500 lb Axle: Hub Bearing Kit for Lippert, Dexter, and Al-Ko Axle # BK2-100

The other thing you can do is measure the inner diameter of the bearings; if both measure 1.063" then both are L44649 and you need the # BK1-150; if one is 1.063" and the other is 1.378" then you have a L44649 and L68149 and need # BK2-100.

Then for grease I recommend High-Performance Grease # L74FR with Bearing Packer # PTW1218.

If you have a grease zerk use LubriMatic Economy Size Mini Grease Gun # L30100 with LubriMatic Marine Trailer Wheel Bearing Grease # L54FR.
