M1009 Military Blazer CUCV

[fitz]

  Just picked up a M1009 Military Blazer CUCV.
  It's a rust free truck from Colorado.
  The drivetrain is stock with a 6.2 diesel, turbo 400/208, and 10 bolt axles with 3:08 gears.
  It has a 6" Pro Comp lift and 35" BFG mud terrain tires.
  I'm not a huge fan of running 35" tires with a 10 bolt gov lock rear end, but it sits nice.  I'll see how the 10 bolt holds up.
  I got a few issues to fix.  It runs strong, but sometimes it stalls letting of the throttle. If I'm lucky, its the fuel filter, but with my luck, its the injector pump.  The fuel filter was last changed in 2008, so I will change it this weekend and hope for the best.  I knew about this going into it. Rust free Blazers are a rare sight in Mass, so whatever it needs, I'll figure it out.
  I will get some better pics once its off the trailer.

very nice find, still looking for a cucv blazer to add to my collection but most of the ones i find around here are the same price as a 6x6

Ya, the Military rates the Blazers ad 3/4 tons, but they just have 10 bolts with 3:08's and a gov lock in the rear.
  I have a few Dana 60/14 bolt combos out of a few M1008's & a M1028  parts trucks, but I don't know if I want the 4:56 gears in it.
  If I upgrade the axles with I think I'd go with 3:73's.

so they just upped the springs then?

[fitz]

  I think they just use the standard 1/2 ton springs. I'll take some pics of the springs in my parts M1009 and post them.
  I'm not sure how the Military comes up with the weight ratings. The M1008's & M1028's are considered a 5/4 ton trucks.

Fitz I hope I'm wrong but I doubt a fuel filter will fix your problem.

Obviously if you haven't changed it in a while doing that first is the wise play.

A clogged fuel filter will cause a diesel to fade out under load or at high speeds. It will be anything but a strong runner as you describe.

However it may be as simple as the governor sticking. At least that is what it sounds like to me from the symptoms you listed.

I got back from vacation and finally got the truck unloaded off the trailer.
  I changed the fuel filter to a spin on set up with a hand primer ( same set up as on my M 1028). That didn't solve the stalling out problem.
  I removed the return valve fitting off the injector pump ( with the glass ball in it). I couldn't blow air through it so I swapped in a spare valve off a parts truck. It solved the problem. Now the question is was if just a little varnish making the ball stick or is it an internal problem with the injector pump. Its running great now, if the valve clogs again, I'll do the injector pump.

The pics of the M1009 & M1028.
The fuel filter picture is the set up on the M1028, I used the set up & mounting bracket on the blazer

Sweeeet.

Very nice!

[fitz]

  This is the fitting with the glass ball in it that I swapped out. The old one wasn't filled with crud like I expected, but you could not blow air through it. You could still see through the glass ball.

Fitz you have a really cool blazer..... Like... Wicked awesome.... Haha.   That would be ideal to have here in colorado for camping and fishing / hunting trips....   Fitz what is the exact tire rim combo/size you have?  I'm curious
