M1165A1 needs steering box - which one?

[dma251]

I have an M1165A1 (I think it's a 2007) serial number 249812. Of course when I got it was missing some important parts, one of them being the steering box. I am aware that around this point the REV models got the Sheppard steering box, but I'm not sure if mine got that or not. Does anyone know how to determine what steering box it had?

EDIT: not trying to be rude, but any time you want to make sure you have the correct part for your version of the truck, the parts manual will be the easiest and most accurate place to look.

Also know, that below the Steering Gear, is the UOC. The UOC, Usable On Code, tells you what models can use that part. If you look up front in the TM, it explains what and how a UOC works, and then gives you a list, of what model truck has what UOC. Makes it easy.

Pay attention to the SN and UOC, the steering gear, center link, Pittman and idler are SN specific

Is it possible to install the old style box (Saginaw or Delphi or what ever it's called) on an ECV? Why did they change the box?

I don't know if they have the same bolt pattern, but if you changed out the box you'd also have to change out all of the steering linkage, as the two are different (so drag link, idler arm, pitman arm; possibly other parts)
The pictures of the two in the manual also appear to have different mounting bolt patterns, so if that's true that would make it a complete no-go from the start.

They changed the box because the heavy armored trucks variants were just too much weight for the old style box to handle.

Potentially however the frame bolt pattern is different. The frame would have to be reworked along with different steering linkage parts.

Or maybe an adapter plate... along with the linkages... I was just wondering.

Thanks for the advice - To avoid turning a minor project into a major project, I will just find a Sheppard box.

am general has the Sheppard boxes in stock.

Unfortunately shepherd has discontinued production of the M83-PAQ2 gear. Stay tuned on that one.

They are a pain and expensive to source replacement, but the Sheppard box is superior to the earlier HMMWV alternatives.
