Geared hub Spur Gears Upper and Lower

It looks like the upper and lower spur gears, according to part numbers, go in both the 10k and 12k hubs.... Is this correct ?
6009542 lower
6009453 upper

Thanks......

These are the numbers that I got from TM 280-24P-1. Am I doing it wrong? Thanks

There is often more than one page/image/list in the parts manual because of the number of differences between the A0/A1 and the A2 trucks.
If your manual is new enough (I don't know if they released older parts manuals from before the A2 series, but it's possible there are some out there on the internet) then you need to make sure to either check before or after the page set you are looking at to see if there is another one for those parts for a different vehicle series.

Here is a short view of the 2 part numbers and their headers.

In this case, you can see it was image number 142 and image number 143 for the 2 different versions of the geared hub internals.












Then the other thing when looking at parts and different versions of the truck there is the UOC after the description. If you aren't familiar with the UOC (Use On Code) it's just a short way of labeling which specific version of the truck that a certain part or part variation was used on.
(I have no idea if you already know about it or not, but this is also for anyone else that might read this thread and not understand the manuals)
