#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

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.

Here you can see the pipe coming across to the cooler. In the upper left corner you can also catch a glimpse of the black 'coolant reservoir' I came up with. It resembles a 4" x 4" x 2" ABS sanitary TEE, because it is. It takes coolant from the heat exchanger mounted on the exterior engine house door then gravity feeds it downward into the intercooler below it. From the cooler it drops down into the 500 gph 'bait tank' pump that lives down near the brake booster. Note how close the cold-air outlet of the cooler is to the intake horn.
