Somewhere on here I saw an amazing set of switches and lights that somebody had rigged up using something like the "Convoy Lights" switch and an indicator lamp for each - using something like the "high beam indicator" light. Like so many things, find it and you better bookmark it because...

Seems that the answer to everything is to look it up in the TM's. Maybe I don't have everything... I have the -10, the four volumes of the -24 and two volumes of the -24P and I am here to tell you - either I am stupid or there are no decent drawings of where the hydraulic lines go on this M936...

On a quest for the rubber inserts and socket for the amber and red Side Marker lights... I looked in the TMs and said words that are not family friendly trying to get the part number. Picture below is what I am looking for. Not trying to be cheap, but I would think if they are available -...

Well, in the grand scheme of things I can't say that it surprised me when I found a little spot of rust was the problem... I have had an ongoing battle with the stuff! I had a persistent air leak that sounded like it was under the drivers side step. There is a wad of air lines in the "box" in...

My M936 seems to be configured just like all the other 939 Series so far as the air system is concerned. On the passenger side, I have 4 (looks like radiator petcocks). I guess they haven't been opened in a while... Sprayed them down with WD-40 and let them sit. Still no go. So a pair of...

Looking for the TM on the HEMAT Trailer. In particularly - Process to turn off the airbags to load and unload the trailer? Obvious answer is to unplug the air and drain but somehow that seems like the long way around... Image is not my trailer. Too lazy to walk outside and take its picture :-(

Is there a source for front window gaskets? The rubber on mine is cracked in a few places. Also really hard, Not much flex at all. I am guessing that is the source of the rainwater happening inside the cab. I can use a business card and slide it most of the way around the "seal" that isn't...

Hi All, These may be old tired questions but I seemed to come up empty trying to search for answers. The indicator lights in the picture below... I know for certain that the AIR LOW lamp is working. Turn on the truck, that lamp lights, the buzzer turns on and until air pressure builds - it...

In the continuing adventure, today as I was retracting the Jib - nice and easy - I had a line break. The one that controls "IN" on the Jib Cylinder. It is amazing how fine the spray can be and how far it goes! What was really amazing was how quickly I got up out of the gondola, took three...

First use of my rotator crane boom under a load. Seems that the Jib (extension) cylindar leaks. Guessing it needs to be repacked. Is there a source for a packing kit for it - or do I have to tear it down first and go to the local supplier?

I have a nice set of six 395/85 R20's under my wrecker. Nice big fat juicy tires! The spare is a (flat) 11.00/R20 that fits the spare tire holder nicely. The tool boxes open like they should. The rotator boom clears the spare... If I happened to be pulling my HEMAT trailer, I have a...

My rear winch operates like a champ. Question is this: Standing about where the white shop towel is to operate it doesn't give you anywhere to hide (duck, get out of the way, call it what you will...) if something goes wrong. I have heard a winch cable flying through the air before and it is...

It seems that I have a pretty good exhaust leak around the bottom of the muffler. Looks like stainless steel maybe makes that connection? Is there a flange that has just rusted away - or has vibration killed it? I have a picture... Doesn't look like there is a clamp on / for the bottom?

My M936 has a Map Box behind what appears to be a new "companion seat" bottom and back cushion above the battery box. Maybe newly covered? Seems that the metal frame that holds the seat back in place is not in the truck. TM TM-9-2320-272-24P-2 on Page 370-1 shows a part number...

My M936 seems to operate differently than the 9-2320-260-10 (Page 2-13) shows. Item 6 in that list says "lever is pushed forward" to provide power to auxiliary equipment. Looking at the picture in that TM, it is obviously a manual transmission and mine isn't. In my truck, that (power...

M936, Step 1 in setting up the wrecker is to engage the parking brake lever. As soon as I pull up the lever the buzzer sounds. It doesn't stop until the lever is pushed back down. (same sound as low air warning) The left warning lamp (red) just above the steering column stays on as well...

Safety First - So I don't kill myself or somebody else... I am new to the M936, but reading the TM seems like the right thing to do. TM 9-2320-272-10 (Pages 2-136 to 2-140) show and explain the use of Shipper Braces that provide boom stability on the road. The TM also explains those other two...

Looking through the TM 9-2320-272-10, Page 93 it mentions that a control switch -on- the floodlights turns them off and on. Nothing happened when I tried that today. I have two white work lights (floodlights) on My 936. Should have been a third one but the lamp under the boom is missing...

So, in the continuing saga of getting the outriggers to slide out of the pocket... I have been spraying WD40 for days. Recently upgraded to Weasel Piss. Snatch, Jerk, Yank and Slam. Finally I got some motion! There is a pin that holds a "retaining collar" that holds the "foot" in place. I...

It appears that the catwalk is a commonly "wiped out" or maybe "wiped off" piece of hardware on these machines. This truck is new to me - delivered by simp5782 who is a first class individual. The catwalk was chained up so it wouldn't flop out coming down the highway. On further...
