Help with 'newer' Rockwell 5 ton axle info

[four_by_ken]

I dont have too much to go on yet, but I hope someone can help me out a little bit with some information and maybe a supplier of parts.

Model is RS15611NFSF
7.1:1 final ratio between the r&p and planataries
Both were manufactured in 1989 by Rockwell International.
Air brakes on both.

I was told they are a 5 ton rated axle, but I think they are more 7 ton.

Does anyone know anything about these, or can lead me in a direction to find more information? Main thing I am looking for is maintenance parts suppliers.

This is a picture of the actual axles.

I was told they came out of these type of vehicles

Right now, thats all I have. I am hoping to get more.

And, just to be sure... NSN is the stock number?

 

[mdlbldrmatt135]

yeah it's the nato stock number in xxxx-xx-xxx-xxxx format

 

[four_by_ken]

There are numbers stamped all over it from what I am told. Is there a location that is better than another to get the number from?

I'll see if I can get the nsn from the housing.

If those 5 ton axles have air brake cans on them that tells me that the axles are setup for use on the m939 5 ton series truck they all have full air brakes on them !!

I am far from an expert, but I think the 900 series uses a top loader axle... and does not use planatary ends.... and I think the 900 is a 6.44 or something ratio.

So, not quite what these are. They are air brake axles, thats for sure.

Are the axles front load like a commerical tractor trailer ?? If they are ,then those axles probablly are used on the M915, M916, M917 and M920 series truck. If you want to use them on a M39 series or M809 series 5 ton truck you will have to redo all the air system for the brakes to a M939 or M915, M916 series truck style of air brake system !!


DO YOU HAVE SOME PHOTOS OF THE AXLES ??

Yes, front load. Here they are...

But, I thought that the 900 series were not planatary axles?

No dice on any of the numbers you posted.....

****... thats not good.




I did find on the Arvin Meritor site an axle that looks exactly like it. The Rf-611 series.

Anyone know of a contact for an Arvin Meritor dealer that would be helpful with something like this?

 

[mdlbldrmatt135]

Bingo... did some more playing around.........

The first goes to a fire truck... the next 3 go to 2.5 ton LMTV's and the last goes to a MRAP

Looks like they are 2.5 ton. No big deal there.

But, at least something is being found!

Now to find a supplier and hope parts are not out of this world!

 

[four_by_ken]

Found out the same axles are used in the 2.5t and the 5t.
