Replaced the engine to frame, braided ground strap of who knows what size with remaining 3/0 cable I have..
Engine cranks faster.. also pull starter number off it.. starter has some battle wounds...

It's a delce Remy Part No. 1993928 — 37MT New Starter
Which is obsolete
Go through application search... Delco remy recommends 8200433 — 39MT New Starter

37MT is 4.6KW@12v
39MT is 7.3KW@12v

Update the starter... Probably crank better when cold

Is there a date code on the starter? If it was made after July 1997, it was made on the line that I did the programming/startup/support on. Yes a cold starter has less resistance, therefore will make more HP.

Only info I could find
Serial number is 93802
Type 300
Model 37MT
Volts 12v with G L after it
Rotation CW..

Everything was still warm temp wise when I swapped the strap for the cable... seamed to spin faster, as if the ground strap was restricting current back to the batteries....see how fast it cranks in the the AM, supposed be around 0° for a low.

Just guessing the 39MT will crank the Engine easier/faster than the 37MT that's on there, regardless of outside factors

Be pretty cool to see if you did have a hand in something

We made the 37MT, 42MT and the 50MT at the factory I was at. It was kind of hush/hush but during that time frame they were starting up a line in Mexico based on the line we started up. IIRC correctly there is a push cap that had an oiled wick in it for lubricating the bushings. Another area of problem could be the contacts on the solenoid, if they are all pitted higher resistance. on a 12V system minimizing voltage drop is critical.

If you can find gear reduction it makes a hug difference in cold weather cranking.

Jeff @ Mumau has a good starter cross reference for Cummins/Delco starters

Principal is a good parts store if you don’t mind the former Gestapo female guards checking your parts before you can walk out. Lol

Kinda winded.... All in all for basically blind shot in the dark..... Nailed few things, slight missed few others... IDK if I completely missed anything yet..

Trans/gear ratio/tire size, rto164713/3.31/255/70/22.5 is home run.
Even at a longer WB 150"/136" it's substantually more manuverable than the dually definetly rides better.
Air ride pretty much Trumps any leaf spring suspension
Air fan clutch is a win..

While the 362/68 is bigger than the WH1C I pulled off, it would not surprise me if drive pressure was above 2:1 when above 1600rpm even, though I've back the WG of some.. I've hit 1350 EGTs pulling 7-8% grades on I64. 1100-1200 is pretty common. Cruise is ~800 all pre turbo temps..
Boost is 15-20#@70 @1650 RPM probably should be half that..
362/74 is next, I'd jump straight to a 464/83 but without a gate I'm worried I'd lift the head without studs. Or overspool it due to shear air flow.

The 11m pump half miss I'd say, I can run 55-60 @35k up a 5% in stock setup, outside afc full travel mod, only time it will roll smoke is in pre boost, once above 10# it's clear

Columbus diesel, ~900.00 to swap out the constant pressure DV, or 1300.00 for brand new 8.3 12m pump

No issuse with the HYD brakes, have enough weight on the rear it put anything laying on the bed or seat on the floor without much effort.

Engine... Definetly has potential, I think someone hodgepodge it together and/or might actually had 240k on it... MPG pretty much mid 8s, seen 7.8-10.3... really think I should be mid upper 9s if not 10s, I'm definitely below fuel consumption test for the 430hp marine 8.3 of mid 8.Xgph vs low 6.Xgph at same RPM
70mph divided by 8.5mpg is 8.3 gph
70/6.5gph is 11.2 mpg

$3.2X diesel isn't helping.

70-75 is really easy right now....unless there's substantal head wind or high profile load
ECT 182-185
fan comes on 195-200
EOT 190-210

Grade speed/MPG current are behind/below when compared to what the dmax did even with a worn out Engine.. avg 9.8 mpg with the dmax for '17.. fresh dmax after rings seated was 10.5-11

Should have sent the pump/injectors off..
Between who knows what pump/injectors combo...choking the exhaust with a small turbine turbo
Really tight gov Springs.. doesnt really help anything..

Am I glad? I'm not sure yet... 6-7 weeks in... right now my OCPM is higher.... definitely Nice having more cabin space.. somethings yes.... Others.. jury is still out on..

I get back in 10+ mpg and not having to slow down for grades I'll be more happy/content with it

Moved my response here as to not get lost in the trucker thread

Did you factor in air fare for trips home/stranded engine costs, as well as engine rebuild cost into your OCPM?

Obviously I try to plan major Maintenance.. usually I take the year mileage and divide it by the sum of everything thats write-off..
Alot of stuff is fairly easy to figure
Oil change... Say 10k intervals is 10-12 changes per year.. I'm 100-120k miles a year.. 6gallon and a filter times number of changes a year...

Major un expected failure it's almost impossible to predict, you just hope you have enough cash on hand to fix it..
I've seen service intervals for 8.3 from 150k to 500k miles.. maybe Chris can give an hour intervals

I know in-frame for the engine is ~4-5k in parts for all Cummins stuff and about 1/3 that for aftermarket.. plus 40-50 hours of labor for a shop

The goal is to have enough cash on hand to rebuild it anywhere at anytime.. plus operating expenses..

I can do the Normal planning.. say it cost 10k and serivice life is 300k that's .03 mile.. realistically.. I'll set aside said money aggressively until I've reached said amount.
