Cant find anything in the TMs on how to get the 5 ball and claw assembly to reassemble. It is obviously doable but after having some close calls on busting my fingers trying to hold and swivel etc I though I might just ask here and save me a trip to the institution or hospital, whichever comes...

All, My S-280 is mounted in the back of my M813. The box has skids that have suspension like qualities that appear to give at least a few inches of movement. When mounted in the back of the bed am I suppose to tighten this down to where the "give" in these skids is tightened down or am I to...

I live in Utah and it doesn't get too cold here but yes, cold is not what the NHC250 likes. Since the NHC250 is a dog to start in the cold, has anyone added an ether injector to their setup to assist in those cold days? Now I do have the heater element, and my primer does seem to work, but it...

Can anyone out there with a M1095 measure the distance between the hub centers for me? I would like to have one of these M1095s and was wondering if I can put matching 16.00R20s on it so I can maximize my possible spare tire options. BTW, I looked through all the TM section and could not see a...

Hello All, My M813 "THE BOT" which I drove 2385 miles cross country from Detroit to Salt Lake has a fuel issue. The rig runs fine on flat ground with a tailwind but is GUTLESS on any hill. I have read some of the other threads on similar issues and have taken these initial steps to figure out...

Looking to purchase a used Detroit 5Ton locker out of a 900 series for my M813. The locker has a single half broken tooth. Still good to buy? I dont see any other damage to the adjacent teeth. From the exploded view it appears the collar shares the load with all the teeth simotaniously and...

Had been looking for some time for an M813 with winch. Not much luck and was always behind another buyer it seemed. Finally found one in decent shape and an excellent price but on the other side of the US from me. The rig was located near Detroit. I know that is a long ways away but I bought...

All, if I buy an M816 what is needed to "convert" it down to just an M813. The differences after removing the Crane/bed assembly that I think I know are: 1. M816 has a heavy plated frame to allow the extra 15K + weight the crane assembly adds. (no modification needed for conversion) 2. M816...
