I'll look again but we didn't find one during our search. Maybe its flush and painted over? Thanks for the diagram :0)

Happy Sunday all! I have a M936A1 wrecker with NHC250 motor. Long story short, one fuel tank was contaminated, pretty much overcame the frame mount filter and the PT pump and engine ingested the contamination. The motor had a severe "diesel knock" and ran very rough. I've cleaned the tanks...

#2 Diesel in Calif just jumped from $3.19 to $3.59 nearly overnight. Tank up before you enter the "peoples republic of" brother. Also, a little 'Huhra" coming from Ft. Wainwright, I was rifted there during the Viet Nam war and served as a 64C30 heavy truck driver 1970-72.

Well I think I had one or more hung injectors. With Lucas injector cleaner in the cleaned tank and some premium 2 stroke oil, the truck now idles nicely and will rev with a bog down and catch back up. I drove it around the neighborhood and found it simply has no power. I kept it in 2nd gear, 3rd...

Yup, I just posted a few weeks ago about this. The oxidation turns into a heavy white corroded powder. One of the sources of corrupting my fuel system on my wrecker. I've removed them from all of my trucks. I may send them off to be cadmium plated or one of the newer tougher anti-corrosion...

Good call, once I resolve this mess I'm going to install a Racor water sepearation filter just prior to the pump :0(

With all the positive comments re Diesel 911, we're thinking it broke whatever the bad stuff was inside the tank. With the fuel filler baskets on these trucks, you can't peer inside the tank. A heavy duty strap wrench and I've now removed the fuel filler baskets off my trucks. They just corrode...

Well not sure what to think now. Prior to using the 911, I've used the regular version of Diesel Power fuel treatment since I acquired the truck in 2012. Only the driver tank was gummed up and received the 911 treatment. The larger problem now is the rough running motor, no power and knocking...

During the winter, temps got down below freezing overnight for several weeks. Concerned about fuel gelling, I bought Diesel 911 and added it to my M936A1 fuel tanks. Every couple of weeks afterward, I would fire the engine and noticed that the initial start would "spike" and the engine would...

Where is the screen located in the PT pump?

Any luck on the NHC 250 shop manual?

Pinon brakes are illegal in most states for on-road use.

Link is inoperative?

Welcome from the California Central Coast :0)

1 for sure for the mid-ships axle and 2 if adaptable to a steering axle.

Nice install! Where did you acquire the H1 Rhino tire carrier and how much $$$?

Being from California , one must exclaim......."Dude!"

Kinda makes me tear up a bit...big sigh

None received? I just sent you a PM and my email address

Dang brother, I drove 5 M939's from Barstow to Paso Robles and 1 M939 from Nellis AFB to Paso Robles w/o any hiccups. (Not all the same day LOL) Of course our service recovery escort was loaded to the gunnels with every imaginable hand and pneumatic tool and jack. Check your truck out top to...
