#846 - Cummins Swap
Author: andy1canada (Show all albums)

Howdy Folks!

Going to give this another try as my first attempt didn't go so well on the 'Diner-conversion' thread (Will update/edit that soon).

Started my Cummins swap by pulling off the bumper; only took better part of an hour. That sucker is HEAVY! Better part of a 100 lbs I bet. Will be looking to knock substantial weight off that baby while still retaining a 5000 lb towing standard.

This will take a while as it will unfold as time and resources permit, so please be patient.

More pics and hopefully some videos (FMC-TV) to follow.

Cheers,
Terry

Finally did an MPG calculation since the Cummins install. 90% of the miles were on the hwy averaging 65 miles per hour, with a good mix of steep hills as well as winding and flat stretches. Fuel full; 80/US gal water = 16,000 GVW. 12V Cummins with 4" exhaust; 3000 rpm Governor spring kit; 60 lb exhaust spring kit; P7100 fuel pump slightly tweaked for performance and economy. Distance travelled: 517 miles Diesel fuel burned: 40/Imp gals = 48/US gal. Improved from about 8/Imp mpg to 13/mpg. In US/gals that would be about 6.5/US mpg (typical) to 10.8/mpg. That's about a 65% improvement over my old 440'! I'm happy with that and will look to improving on it going forward. ie. would likely have better economy if I was cruising closer to 60 mph. Eh.

Solo - the 'camp-boss' says "Adios mis amigos"!

First night... serenity.

Roof rack turned out to be a godsend. Tons of room for extra firewood etc. She sits a tad higher in the rear if you noticed, and that's with only 20 psi in the airsprings.


After sitting for a year she's good-to-go to the lake for a few days. I think the 'Double-Rainbow' is a good sign that all will be well.

FINALLY! The old Ford Taurus fan steps back into service. It's pulling cool air through into the engine house at around 5000 CFM. I'm confident #846 will be a robust and cool-running 'Desert Rat' when I'm done with her.



Behind the new intercooler rad you can see I kept the awesome trans cooler from the 440' install that a PO (trucker) had installed. I've also added another smaller trans-cooler on the main radiator to further keep the 47RH cool.


This is the coolant heat exchanger I chose for the intercooler. It features 8 AN fittings which are about the largest flow for this class of cooler. It's also compact enough that I could work it into the engine house door cooling-center.

The ABS fitting I chose for the reservoir made it easy to adapt down to a 1" braided hose off the top (4") to get me a simple filler hose over to the rad fill access. The screw in plug also helps with bleeding air out of the system.

Overhead view of the live-bait-well pump. I also tee-ed off the outlet hose with a drain-cock fitting to easily drain the (approx 2-qts) from the system if needed.

I cut up some 1/8" plate to mount the left side of the cooler on while the right side simply bolted into the main frame rail. It was solid then but I also elected to put a small (adjustable tension) pipe strap stay on the top as well.
