You can appreciate the “beef” of the GMC/Chevy 3500HD trucks, a stripped rolling 3500HD chassis weighs more than a running C1500!

When posting on this site you won't have to explain what the 3500HD Beast is! ie 19.5 wheels, straight axle, 10 bolt wheels, 15000lbs GVW, 4 Wheel Disc Brakes etc

Engine-Driveline-Wheels-Tires / 6.5 was leaking fuel from near filter
« Last post by RPF207 on September 01, 2018, 09:15:29 PM »
Figured I’d post my experience from today. Started Monday when I was delivering fired wood. Got out and noticed a small puddle of fuel, popped the hood and all around the fuel filter area was wet. Got home and shut off the truck and figured I’d get to it when I had time. Went to start the truck Wednesday to see where fuel was coming from but it wouldn’t fire up anymore. So I was out of luck there and decided today to  pull the filter housing and inspect it as well as the 4 rubber fuel lines in that area.
      Never actually came across anything that really stood out as a leak after inspection so I bought all new rubber hose for the 4 different lines, new filter with gasket and a new Oring for the fuel heater on the bottom of the filter housing anyways.. FYI the fuel heater oring not only seems to be an odd size but is a real pain to keep on the housing. Only oring I could find at Napa that would work was slightly smaller in diameter but slightly larger in thickness. It ended up working though, had to stretch it, hold it on the and quickly install the heater.
     Two of the rubber fuel lines snake through from front to back of the intake manifold on my 6.5. To maintain the original path I took three feet of weed whacker string and pushed it through the fuel line until it came out the other side, then removed the fuel line letting the whacker string slide out and stay in place. Then pushed the whacker string into the new fuel line and pulled it back through into the original path. I was worried that not buying preformed fuel line would result in kinks but everything turned out fine.
     Bleed the system, fired up the truck and now no more leaks. So one of those things I messed with was the problem but showed no obvious signs
3500 & 3500HD Parts WANTED / Need trans dipstick tube.

Trans dipstick tube is damaged on my 2002 3500hd. If you have a used one for sale please email me at:
The lift is an Altec AT200A. Does anybody have any manuals for this model? Preferably schematics.

I am aware of what is needed to make this truck function as a crane. What I need to make that easier is a hydraulic and electrical schematics. I have started the process of tracing everything out and taking out unnecessary components. It would just go much faster if I had diagrams to work from instead of tracing everything out. It would also help if the wiring and name plates were not misted with white paint.
Keep in mind that boom was designed for a max capacity of 250lbs, some were 500lbs but your truck probably doesn’t have any outriggers. Most winches if not all will be capable of hoisting far more that the boom is capable of. Even a full size line truck with 42’-100’ boom and factory material handler and winch is rated at only 2,000 lbs hoisting capacity.
I just bought a 1997 Chevy 3500HD. It has 6.5L, NV4500, PTO hydraulic pump and an altec bucket. The bucket was removed but the boom and hydraulics are intact. I want to add a winch to the boom and use it like a crane.

I am trying to find manuals or hydraulic schematics for the bucket. Any help is greatly appreciated. I will try to post some pics of the name plates after I get the paint off of them.

I kinda figured that might be the case, but wanted to ask anyway seeing as I already have a functioning NV4500...

Thanks for the link!  I'm figuring this out as I go....luckily I have plenty of time for this oldest son is only 5 and the '63 C30 is to be his high school truck, then the little brother as well.

If you can post the links for the tail shaft and brake assembly, I'd be grateful....apparently my google is weak.

Wow, a little searching and I did turn one up, cheap too!
Park brake tailshaft housing

Also found the shaft cheapish at a place called c&m, don't have the link handy at the moment (hate searching w phone)

The park brake assembly looks pricey so far but I didn't see many options yet to compare prices.

Not sure who would part an HD nv4500 to take that assembly off, but you'll need the tailshaft itself, too.
