I don't know if it was pulling any real weight. It was an old video too, but it did get me looking around more and seeing that yeah, I usually see them in single axle trucks, sometimes gas or small diesel, but not a lot of the bigger class 8 trucks. hmmm. It's looks like I'm running across...

Thanks again for your input. I have zero experience with that box. I was mostly going off of a YouTube video I found with a Spicer 5 speed and 7041 behind a Nifty 250 on a cab over. I did read about the linkage interference when the joints get worn so I’ll try to design around that best I can...

Thanks! You're probably right about the 18 speed. I may end up wishing I went that route in the end. Thanks for the input on the 7041. I haven't found any torque/hp specs on them (probably because it's an auxiliary so who knows what gearing someone puts between it and the engine) I'm going...

I have an M820 chassis cab (so the extra long wheelbase) that I am modifying into a tractor using a '53 International Metro van body as the cab. I'm sliding the tandem all the way to the back of the rails, moving the Rockwell transfercase back and (I'm thinking atm) I'll add a Spicer 7041...

Hell yeah! That sounds great!

My car has a water-cooled turbo and that coolant is shared with the engine, which feeds the heater core... so technically, your thoughts are spot on. I don't know why all turbo compressors aren't water cooled (on water cooled engines) actually. It seems like a very effective way to help cool...

I think you'll really like the 17 button. I put a 15 in mine and I have to keep a pretty light touch on the pedal to keep the fuel pressure down a bit, where I like it. I'll probably end up putting a 17 (or close to it) in. I don't know if you have a fuel press. gauge or not, but I'm glad I...

Just jot down your egt's, boost, fuel pressures (if you got em) etc. I'm curious to see what you have and can selfishly learn from it!

I for one am looking forward to hearing all about how she runs. Nice work!

Also, after I changed the oil, there are some fairly big trees that my friend cut down to 4 ft. high stumps that his tractor can't seem to budge. I was gonna rock them with the truck but when I lined it up with the frame rail and pushed, the back wheels spun, the front axle engaged and it just...

Ok. Trip went great. The engine feels significantly stronger and it maintains 60 mph (gps) with a light throttle now. It feels like a 14 liter engine. I ran it at 2200 rpm, at between 200-210 psi pump pressure and the EGT's stayed at 900 F or lower. I leaned on it kinda hard on purpose on a...

Just drove it around town to check things before the trip tomorrow (which will be a 2 hour drive on the Interstate) and I kept the rail pressure down below 200 psi and the egt's hit about 700-800 F. I was only as high as low range 5th, though, so hardly a real test. I'll be keeping a close eye...

The one that came out was a 45, which had the rail pressure at about 160-170 ("snap test"). It would go to 2200 and I would be careful to not spend much time there. With this higher rail pressure, I let off at 2400 before it could go any higher. The EGT gauge is going in today for it's 25...

I don't. It still had the expansible van body on the rear when I bought it and just looked... ex military. I figure either somebody was into the pump before me to ring it's neck, or just changing the button affected the governed speed and had a huge affect on rail pressure. I'm hoping it's...

I have an M820 I plan to modify extensively into an "expedition rig" over the next 12 years when I hope to retire. I'm just tinkering and playing with it now, slowly adding things that will eventually come together. The end goal for the engine is turbo, piston coolers (I have a machining and...

I had the vents out last year. I replaced the hub seals before I drove it cross country, but I'm not above pulling and checking them again. I like the raised remote option. Thanks.

Right on. Thank you. I was hoping that would be the case, but I figured I'd ask.

Anyone done the pinion seals before? I got a couple leakers. I see the seals are readily available and cheap. Just wondering how much of a fight that nut/bolt holding the pinion "yolk"? will be once I get the drive shaft out of the way. I'll also check the axle vents before I go tearing...

I like it.

It didn't have anything posted by the truck (that I saw), but it seems other members here know quite a bit! I just thought it was pretty cool and I also thought the truck had the larger wheels/tires of a bridge truck, which I'd never seen. I was hoping they'd have a Pershing missile there (my...
