Replacement Bearings L44649, LM48549 and Grease Seal With 1.71 Inner Diameter


I've pulled one of the tires and brake drums back off and have the below part numbers off the bearings and back seal. OUTER BEARING: TIMKEN L44649 ID: 1.062 INNER BEARING: BOWER LM48549 ID: 1.374 MEASUREMENT C ON THE DIAGRAM INNER SEAL: NATIONAL 42251-S60 MEASUREMENTS I COULD GET B - 1713 C- 1.374 D- 1.062 E - 0.75 So I think I just need the bearings, associated racers and the inner seals.

Thanks so much for that detailed info, and we do have the bearings, races, and grease seal that you need, which are the following:

- Replacement Trailer Hub Bearing # L44649
- Replacement Race # L44610
- Replacement Trailer Hub Bearing # LM48548
- Replacement Race # LM48510
- Grease Seal # 58846

The bearing LM48548 is a different number than the one you mentioned for the Bower inner bearing, but it does have the exact same inner and outer diameter so it will work perfectly.

Apart from that the only other thing you'll need is grease if you don't have it, and for that I recommend the Prime Guard Wheel Bearing Hi-Temp Red Grease # L11380 with Bearing Packer # ALL647646.
