Bearing Hub Change

[gwbarm]

I have a small motorcycle hauling trailer with 1 1/16 id bearing L44649. I want to replace the hub with a haulmaster 4 lug hub from a harbor freight kit #90154 but the bearings are 1 inch instead of 1 1/16. Does anyone know which bearings i might be able to use in this haulmaster hub that would work for my larger spindle.

All these dexter hubs will fit

An industry standard for trailers up to 7000lb axels
Why downgrade from what you have now to specs for an 1ooo lb capacity ???

Thanks for the response. I was given these hubs with brand new 12 inch tires and rims attached . The tires were 4 lug 12" and my existing is 5 lug 8". I needed new tires and the bearings wernt that great either, i just got the trailer last year and it had been sitting for years with leaky seals plus i had 8 inch tires so this would be an upgrade for the tires, but so far i havent found bearings that fit this harbor frieght hub correctly in 1 1/16" i think probably because its metric made in china.. I thought some of you guys might have run into the same problem at some point. I may end up ordering the 2 new hubs from the link you sent thanks again.

I generally go to professional bearing supplier (commercial) with similar bearing problems.... They usually have cross references with inner & outer diameters and width in a catalog and can pretty much find any bearing that may exist that may work for you....

Also you may have to convert to metric (mm) if inches will not work for you....

Standard bearings are metric with inch sizes being "odd man out".

Also you may have to convert to metric (mm) if inches will not work for you....Bearings and the housing/shafts that they are used with are precision fits. I'm not sure if Dale is suggesting "compromising" the fit by getting "close enough" but "close enough" isn't close enough. If a bearing house can't get you the exact right bearings, do something else. A sloppy fit is definitely going to be a problem "down the road".

Problem with going to an odd bearing is if you need service down the road, overheat an standart triler bearing and you will get a replacement anywhere, cook a oddball, you may be stranded a week trying to get a replacment

I never suggested anything other than "EXACT" fit..... My reference to inch vs metric was that the original measurements were in inches ( in first post), but that may not be accurate, it may have to be measured in "mm" (metric) for precise fit....

As you point out the original measurement was in inches. He also cited the bearing number (which is a 1 1/16" I.D. bearing) and he clearly states he measured the shaft at 1 1/16". It, therefore, seems pretty certain that it's a 1 1/16" setup.

There is no converting a 1 1/16" shaft to a bearing with a metric I.D. short of some custom machining. You must to use a bearing with a 1 1/16" I.D. If you want to use a different bearing with a different I.D. yer gonna have to change the axle (or stubs if possible). No getting around it.

Sorry for the confusion. What i was interested in doing was replacing the 25mm id 30205 bearings with 1 1/16 inch 44649 bearings in the haulmaster hub and was wondering if anyone had ever done this and would it work. If the race 44610 for the 44649 bearing is the same width as the 30205 race it should work. The 44649 bearing fits in the 30205 race ok but the pitch is a little off not sure how much that would matter, Wow! now im confused. I think i ill just order some new hubs from etrailer.com as Martin suggested. Thanks again for the link.

With "half duplex" communications with a "time delay" there is lots of room for confusion! I'm not sure what you mean by "the pitch is off" but suspect that the angle of the inner race or cup and the cone is different. If so "it ain't gonna fly" for long. Best bet, as Dale suggested, go to a bearing house and they can set you straight or buy new hubs as Martin suggested. You might consider buying an extra as a spare. Spares, IMHO, are a good thing.
