I hate packing bearings. Everytime I do my nose seems to itch more than usual

I bought a tool that sandwiches the bearing between two disks and you pump grease in with a grease gun. The extra grease left over in the tool gets packed into the bearing or into the hub. The tool definitely speeds up the job but my nose still itches!

how many of which is needed for all wheels with two axles. Not sure which brake drums I have on the 30Ft '05 model classic. (trailer still in florida till april)

I do remember the PO saying he had replace rims and tires with 16" LT so guess they were 15" from factory, would that make them 12" brake assembly?? the manual I have shows the OEM as 15" tires all the way to a 25' model.

American or European made TIMKEN is the ideal.

SCHAEFFERS #223 grease is my other.

I agree
American made or Chinese made.There is difference in the quality of the bearing even if they are both branded Timken.

Even if they were the exact same quality which I believe they are not, I will still try and buy US made products. That goes for everything. I will pay more to try and keep the hardworking men and women in the USA in a job. It's the trickle up effect. Small effect probably, but if everybody did it then who knows?

Here is some information regarding bearings.
All types of Anti-friction bearings, ball, cylindrical roller, tapered roller, etc. are manufactured to different tolerance levels, most bearing manufactures are members of the Anti-friction bearing manufactures association weather made in the USA or ?. Check out the link below and it may help you when you purchase your bearings.

We ordered the Timken brand: four of Set 4 and four of Set 17 bearing sets and six of the Timken 442251 seals in case we screwed up a seal or two up putting them in. We will have a complete spare set as well. These are for the 10" brake drums associated with the 3,000 pound axles of the 23D. I do not know the sizes of the bearings and seals associated with the 12" brake drums and higher capacity axles.

Switz,
Do you know the origin of the Timken wheel seals?

carl2591 · 03-11-2016, 06:49 AM

So i guess set 4 is outside and set 17 is inner bearings.. I like the 6 on seals for screw up..

Wonder is airstream would have that info or maybe the dexter axle folks for sure.
thanks

I see on the 5000 lb axle the bearing is

450659 Inner bearing, #25580
680364 Inner race, #25520
450658 Outer bearing, #LM67048
680365 Outer race, #LM67010
680370-100 Grease seal

found them a amazon for 15.69 each for the 25880
the lm68048 were 12ish each.. race is extra like 10 bucks but not bad for US made product.

Moflash · 03-11-2016, 08:12 PM

My 2000 Safari has 3000 lb axles with 12 x 2 brakes.
I'm trying to figure out which bearings I need.

Can someone tell me which set numbers are inner & outer?
Or, the part numbers for bearing/cone & cup/race I need for inner & outer?

dbj216 · 04-17-2016, 08:03 PM

I believe for your 12 x 2 drum brake you will need the following bearing part numbers:

Large inner: 25580
Small outer: LM67048

Bearings are made to a standard. The part number is usually marked on the cups and cones. All manufactures use the same part number.

You will have to verify the OD and ID of the grease seal you need. There are a lot of variations in grease seals. Again, the part number is usually stamped on the grease seal.

You will have to go shopping for the Timken bearings as there are so many lower cost bearings out there.

You might want to rent a cup driver to pound them out and then back in the drum. Some folks can do it with a punch and hammer, but I find the drivers work better. Auto parts stores rent them out.

Thanks!
Those numbers are what I've found in several posts, just not sure how consistently they are used by Airstream and if they are used in my trailer. I guess I'll have to pull a wheel and look. I've greased the bearings many times, just never recorded those part numbers.

Lota bearings come from Mexico.

Moflash · 04-18-2016, 06:47 PM

Not all Timken bearings are made in USA.You have to seek them out.Found them on Amazon.

Everywhere I've looked, all Timken bearings I've found have been made in China. I'm not buying those from Asia.

US made is what I would like to find. Canadian or European made I suspect would be equal in quality.
What are the options?

Moflash · 04-18-2016, 08:15 PM

As I said Amazon has USA made Timken bearings if you search.

Some SKF and most FAG, ZKL and INA bearings are made in the EU.

I'm not having any luck finding the Made In USA Timken bearings on Amazon either. Do you have to go to Ebay?
