Replacements For Hadco Trailer Axle With Hadco 3109 Hubs

Question:

Need to replace a hub. Hub casting HADCO ENG LA 3109. I was able to clean up bearings and seal to get the following part numbers. Bearings: LM67048 [outer] and LM501349 [inner]. Oil seal is 5M HADCO 3109 5M. I was looking for a greased hub kit. No luck. I have also had no luck finding a hub [maybe obsolete?]. Could you recommend a replacement hub? Please see photos below. Thank you.

Though we do have the replacement bearings, races, and seals available for your Hadco 3109 hub (which I have listed below), the combination used will not have an equivalent replacement hub available, unfortunately.

Replacement Trailer Hub Bearing # 501349
Replacement Race for 501349 Bearing # 501310
Replacement Trailer Hub Bearing # LM67048
Replacement Race for LM67048 Bearing # LM67010
Grease Seal # 1105-100-035

If you are wanting to replace the whole hub though, your best bet will be to replace the whole axle with something that uses a more common bearing combination. This will require a few things though. I couldn't find the capacity of this set up, so this will need to be confirmed as it will determine which bearing combo is best. I included a link to all the axles we currently have on the site for you to check out.

Next is the axle measurements, mainly hub face to hub face and center of spring seat to center of spring seat. I included a quick picture of what I mean by that as well. This can cause issues as the axles we carry may not match what you have, especially with it being an older axle. If this is the case, you will need to contact a local Dexter dealer to have an axle built to your specifications.

Last will be the bolt pattern of your hubs and wheels. I included an article we have specifically on this subject as it comes up quite often
