Oops. Beer goggle posting. Wrong thread, fixed.

I’ll just make a log splitter out of it.

I’m not an engineer, I work at the bowling alley. Davis is a good guy. I just drive him, and most others, nuts sometimes.

So, ummmm, let’s see how many people I can make mad. I just had a Cummins ISX 15L engine land in my lap. Anybody have an M939a1 or first gen front engine mount frame cross-member, rear mounts, and doghouse (both for NHC-250)? I’ll probably still go ahead with the ISL-400/13 speed since it is...

This thread contracted the plague as soon as GR said he may not be going.... :(

That may pull the rears in some, as I don't think the dish is as deep, which is why people go with those on the fronts and they prevent rub in a tight turn, well, as tight as a 9 can turn, anyway.....

Solar done. Torque rod link ends next, then motor. Ever seen an electric meter run backwards?

I used to shift to neutral when rolling up to a stop. Will probably stop doing that now for the remainder of my auto trans life in vehicle, after reading this.

...or, swap out the slush box for a manual trans. Nice yummy 13-speed, double-over.

How do you know if somebody is an engineer? Don’t worry, they will tell you. Pretty sure all the M939 trucks got the ABS rework. Case closed?

So glad you have good humor over it. Yes, you’re right, school bus to be even more accurate.

Most reliable upgrade for a 250 is to put an 8.3L in its place! Sorry, just had to say it....... Can't beat the sound or low speed torque of an 855 engine though, I will give it that, but they are thirsty and get asthma once you get close to a freeway. Please post any changes you make, we...

Deliberately, anyway....

Congrats! Picking up my 925(a2) from states away was the first thing I drove, out of open heart surgery. Exciting time for you, welcome to the club.

I bought an offset 2-1/4” “striking wrench” for $45, then thinned it down sideways with a chop saw. Now drops right into the upper nut cove. We’ll see if enough room to manuver it. If so, will be happy to loan it out when I’m done with it.

Considering future servicability, I purchased stainless #10-24 x 3” hex headed bolts, washers, and nyloc nuts, to use instead of cotter pins. Will lather them up well with anti-seize first. The cotter pins seem to seize and become non-removable for whatever reason. We’ll see if these fare any...

Engine block ground wire is pretty weak since the block grounded loads are small to none. If you are upgrading the alternator output, best to run both alternator + and - wires back to the starter + and - terminals, since these are heavy cables back to the batteries. That is how todays over the...

If it is a stock starter dash switch, it is exceeding its current rating. This is why the relay was installed from the factory.

They do have temperature compensated voltage regulators, the higher the temp, the lower the voltage, and vice-versa. This deliberate, and is to keep the batteries from boiling (can use higher charge voltage in lower temps to recover batteries quicker).

This is the exact same alternator in use on todays over the road trucks, without issue. You overloaded yours continuously running 6 electric fans including (4 on the radiator, 2 for the A/C). You overloaded it, so it went into thermal shut down, per Delco design, like you overload nearly every...
