Wheel bearing size

[Flynavy]

I am going to pick up a new to me 75 Tradewind in the next week or two and I want to take a couple sets of new bearings with me just in case.

As per the service manual a tandum calls for the following:

LM67048 outer
25580 inner
42385 seal

I stopped by the local trailer shop and he has the bearings, but he says those numbers are for a 5000# axel. The serv.manual indicates the 25' Tradewind has a 2600# axel assembly. Being as the AS is 500 miles away I can't physically match them up. Would the 2600# axel have huge bearings as the book shows or am I missing something?

Thanks for the help.

Paul.

The bearing numbers are correct, but the number for the grease seal is for an el-cheapo seal.

Thanks for the reply Andy. The shop near me had a kit with the race and seal included, so I'm not sure about the seal. Why did AS use such a large bearing on a 2600# axel? Are the spindels all the same regardless of the axel size?

Because you have 12" brakes, they come with larger spindles than used on 10" brakes which are more common for that capacity axle.

Tandem axle RV's, place tremendous stress on the tire, wheel and bearings when making a turn.

Cars and trucks don't have that same problem.

Simple answer is larger bearings.
