You can fit 3 jakes heads on there without cutting a hole in the hood: https://www.steelsoldiers.com/threads/3-jake-heads-under-a-stock-m809-hood.195031/

How many of you 809 folks have battery box covers/steps that hit the bottom of the cab? My truck has the plastic batt boxes and has always hit but now that I have fixed the curled plastic, it definitely does not want to go back on. I'm thinking of cutting 1/2" of height out of it...

Lots of cool references! Don't forget to mail in your suggestions on how to improve the manuals or correct mistakes & typos...lol

Roto-broaches work really well on hardened steel frame rails !

Is that bridge formula adhered to by all states (national level) or can it vary state-to-state?

This is a similar thread : https://www.steelsoldiers.com/threads/weight-limit-for-5-ton-axle.80210/ Pretty sure my M809 axles are #44,000 units

Typically, doesn't the DoD own the "Technical Data Package" that is produced for a given contract and is free to have those designs manufactured by an entity of choice? Did Oshkosh develop the TAK-4 suspension independent of a military contract?

Those brakes are the gnarliest brakes I've seen on here since I joined! Lots of work

Even with my stubby muffler the loudness is manageable for about 30 minutes, but with the stack in the factory location the noise gets to be fork-in-the-ear sorta fatiguing. The stack behind the cab would help or a spiral, noise reducing insert like @Lonnie installed could help.

I found a way to add a front jake head (25B) without cutting the hood panel - only notching the hood stiffener cross member.

I also wonder about this especially with these being designed AFTER we had the 7.5 ton Mack NO with its massive cab. That being said, I like the proportions of a small cab with a massive hood!

Do you know what kind of engine the intake and cross over came off of? It looks like you could still fit 2 jake heads (front & back) with that setup 😁

That setup looks good, clean, open, and simple. I like the retention of the cold start pieces and I'm glad I didn't see any plumber's tape anywhere.

I see, I see. I've read a few opinions on what max pressure a small cam can handle and they very between 200-230 psi. What pressure would be your max and have you come across any official number from Cummins?

How does a needle valve on the gauge affect the pressure that the pump puts out?

That first picture truck looks a bit like a KM-500. What are your eventual plans for your truck? Full resto?

Was there only one?

I saw The Untouchable 5-ton at the Auburn, Washington 2024 Veteran's Day parade this year so I'm assuming it's not the one listed from New Jersey (can't confirm, however). I don't have any details other than these pics:

Looks like enough gold to warrant free entry into the lowrider show!

With the heater drawing in warm air from the cab on continuous recirc, the heater should get nice & toasty. Brazing the leak shut on the heater would be a more affordable option than replacing with the new $230 units...just an idea...
