Thanks 1954 COE, don't have any "in process" pics during the rear hitch build (it was a hurry up and "gitter done" weekend project). The front weight added roughly 8-900lbs, and like I said, for most towes it has helped a great deal. When I pick a truck and my steer axle loses safe "road...

Ron, I thought before about using removable wedges under the rear axle, but the 936 is more convoluted in the frame axle area than the older juice brakers? If a length of hardwood was temp "clamped" to the frame over the grommet would do the same job of filling the void and moving back the...

wreckerman, I think that I would definitely have a good time "absorbing" a beir while studying the finer characteristics of the hydro-chock engineering of your old machine! Regards, Bob

I have also grappled with the trunnion being so many feet away from the hook. I still plan on putting air springs between the rear axle and frame someday to at least get a couple of feet more leveredge. Putting about 900 pounds counterweight on the front bumper has helped out for most tows...

I should have said that I had called for a hoisting bar and extension leg assembly off of a wrecker body...not the crane portion. The bar grease plugs are 1/8th pipe recessed "allen" style (about a 1/4" long) and set flush with the tube. External plugs or zerks would be a definite concern as...

Zebedee, I have the same/similar holes in my hoisting-bar (engineered/fabbed by me coincidentally, originally by Holmes Inc. I'm sure)... mine are plugged with 1/8th recessed pipe plugs. Once a year or so I plan on removing the plugs (looks good on paper at least), installing zerks, and 10-20...

Whenever we scaled the steer axle on the m936's, they usually came in around 13,500 pounds. My front bumper counterweight is nearing completion. When done I will render a report with pics. Regards, Bob

If I recall correctly, when the A2 family was introduced the wrecker front weight "add on" just about made up the difference in weight between the 855 and the 8.3 engines (just a few hundred pounds..maybe 500?). FWIW, it is hard to judge the weight of steel in block form (plate, bar...

I have been in the process of fabbing a front end counterweight for my M936 too, it will also double as a center pin hitch point for anchoring/pulling purposes. It should be between 1000 and 1200 pounds when completed. I have found the front to be too light on the steer axle with more than 5...

I used an 1-1/2" GR8 FT bolt that started out about 6" long (half threaded, half not) with a slotted/castle nut on the front side (with flat washer) to adjust for wear (if ever needed) or disassembly (if ever needed). The front and rear rotating halves are 1-1/2 by 5-1/2 inch bar stock about 12...

Sorry about that, lets try this again...

Here are a couple of pics of the hitch I put on the back of my M936 this past year. I can back into about any vocational truck, or probably tactical too, and within five minutes have the disabled vehicles tires off the ground. For most "civilian" trucks, the hitch legs ride about level. I...

You will definitely want all three dimensions of movement between the wrecker and disabled vehicle. Most of the time your attaching chains will not be hooked at the same lengths...without the towbar being able to twist it puts a lot of force on one side. I built a holmes 750 "like" arrangement...
