M936 Wrecker - Better Plumbing Guide for Hydraulics?

[Mullaney]

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 .

Attached are the only two pictures I could find of what the TM calls a "Swivel Assembly" (in crane world it is called a Rotation Manifold"). I can't for the life of me find a reference to the lines that feed the "Swivel Assembly". Am I missing the big book of fixin your wrecker by chance?

Tim,

There is no diagram. There are some pics in this thread. https://www.steelsoldiers.com/threads/rescued-m816-wrecker.132200/page-19#post-1995354

Thanks Wes.

I was just sure I had to be overlooking something. The link you sent confirmed what I needed to know about lines. The rest I will get with a little more "seat time". It seems strange the way the air and the hydraulic lines are weaved under my truck.

One of the things I was hoping to see was the electrical connection through the swivel assembly to supply power for the spotlights. Guessing if there are brushes inside maybe? If so, it doesn't appear to be a part that can be ordered... The swivel in the TM appears to be a "complete replacement" part?

I think time and degreaser will help me find a few things hidden in the muck.

Good rain suit. Goggles with face shield. And a steam cleaner.
Crawl under and not care how dirty you get

Or leave it be and it will never rust

I need to figure out how to redirect some of that oil up onto the sides of the bed... Make that rust stop! That look is definitely improving lately though. Slag gun like you would use for welding chips paint almost as well. Mask, Hat, Gloves...

Steam rather than a pressure washer would definitely be the trick. Wonder if those can be rented? I guess they rent everything else so why not? Never needed one before - but that would definitely be the trick!

I am painting my M925 and I washed the underside two times and man did I get dirty!!

Any particular magic other than what Wes suggested? Rain Suit, Goggles and a Face Mask? Did you rent a steamer - or already own one? Any particular kind of cleaner that you used?

We print for a guy with a compnay named X-treme Clean. He has a degreaser called "Red Roost" and that stuff is amazing for normal cleaning. I haven't tried it on my truck yet - but that might be a heck of an idea... It just melts the crud off our printing machines.

I just used a power washer and some degreaser. The Red Roost may work great.

Steam and dawn dish soap works pretty much on everything. And it won't damage anything most of the time.

New News on my M936: I have replaced the 1 inch hose from the valve body on the passenger side (rear winch controls) that connects to the hydraulic pump. JIC fittings on each end. One male, one female. I used a piece of rope zip tied to the hose to pull out the old - and the same piece of rope pulled the new hose back into the same path.

Discovered a check valve attached to that hose. Picture Attached.





Picture just above these words is the check valve in place, affixed to the pump. Nice and clean and shiny... So, I am operational again!
