I resoldered some pins and made an additional ground for the cluster. Then I climbed underneath and cleaned and reseated the speed sender at the tranny and bingo I have consistant speedo and odo function again. I've just got one headlight to fix and the aircon goes to zero pressure when the compressor comes on as repairs other than painting.

The diesel beetle assists the Ram 1 ton truck:


Went in there easily with an engine hoist.
Much more fun getting it out with a truck mounted crane. I met the overhauler half way.



Shiny new overhaul late transmission.

What is the new and old rpms @60mph? 1)gear chang 2) trans swap?
---port match the ehxsost manafulld on both sides .
Wrap it ... I used the extra thick wrap 1.5 rolls for man +hot side ehxsost...
Exhaust Heat Wrap
And T3 Turbo Blanket..
Have the man. hot tanked (to de rust) and 2000+ ceramic paint.
This dropped my under hood temps to under 200 can stop at the top of a 7mile grade pulling 1000f EGT(wide open ) pop the hood and hold on to the man. With out 3rd degree burns. The wrap reduced my 1psi point by 100 (from 600 to 500 ) = more efficient turbo. This drop was an across the bord shift.

---
kafer65. I make the same recommended ehxsost mods for you...

Keep the after cooler. Add a late 1st gen inter cooler/ radiator (early 1st gen too small for intercoolers per dodge/ cummins) put the aftercooler on a separate radiator ( stock is engine coolent180 intake charge =15% reduction in power from un burned fule per Cummings )my late has 15% smaller injectors and the same 160hp /400tq only difference is injectors and IC Vs aftercooler

You might look in the archives of Diesel Power Magazine, I remember reading an article about a 1st Gen Cummins that they purposely did all the work to make it more fuel efficient, and if I remember right, it was a stick shift and a dually at that but they took part of the duals off and used masking tape to tape the wheels smooth, I will see if I can find that article and hopefully post a link!

With the new gears it was ~60 MPH at ~1750 RPM.
The OD ratio went from 0.79 to 0.74
This is a change of roughly 6.25%
This brings it down to ~1640 RPM
I use the ~ because the tachometers on these things are not precision instruments
So now I am below the peak torque of the standard cam.
I have a call in to the cam manufacturer to see what they say about peak torque.

Color me surprised..
07=1600 peek tork 24v 5.9
07.5=1500 peek tork 6.7
With your larger 33.83" tires vs31.73"
Taller gears 3.72/3.42 vs 3.55
Your spun up tighter 1750/1640 vs 1605 ( calculated including 5% extra for no lockup)
The difference is a.79/.74 vs .69 OD in the late 1st gen (91.5-93).
In my opinion your 1640 is perfect for 60mph. As the engine boogs down/lusing rpm the tork gos upto peek. Seeing as you are building a tow truck insted of a mileage monster. For me its 65mph that allows this drop to peek.

I run 30~31" tires 99% of the time.
I will be doing aero mods so a 65 MPH cruise will be do-able.
