#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

Plumb and square to the prop with standoff shimmed with 1" styrofoam pads.


This proved a good way to assure the rad was held parallel to the fan without damaging the rad fins.


Here you can see one of the two heavy side mount brackets I decided to use to carry the primary weight of the rad on each side. This one needed to be lowered about 5" or so then welded back on at the same height as the support just beneath it.


Adhering to my mantra of 'keeping it as stock as possible' throughout this swap, I decided to re-use the OEM rad struts. Here's the parts ready for reassembly.


Seriously, who could not re-use a thing-of-beauty such as this 1/2" lock-nut? Can't buy stuff like this any more.


GTG!


On to the shroud. Found this chunk of 16ga. SS sheet metal I had kicking around that was tailor made for this job. Stuff was pretty hard though. Went through about 5 jigsaw blades to cut this 80" circumference. Added 1 1/2" to the fan circumference for 3/4" blade to shroud clearance. Found some 1" angle brackets I had on hand and had-at-it with some 3/16" rivets. Yee-ha!


Tin snips on some aluminum flashing then a few more rivets and boom...

Done. The fan will sit almost exactly 1/2 the blade depth into the shroud. Note: the SS sheet metal is over 3/4" above the rad core face, so there's room for the fan air-flow to reach most all of it.


Included this to show the repositioning of the lower heavy angle bracket. You can see the four holes just above it where it was originally. Ground off the inside heads of the four heavy iron rivets that held it then pried it off from the outside with a cold chisel & hammer. Also, the big bracket above it with the round hole is not needed and could have been taken off. You can just see the 1/2" bolt above it sticking out at the top of the rad and this is where I decided to attach the angle support struts from the original set up.


Port side view of the final mounting of the rad. Again, it's a made in Canada Spectra Premium all aluminum downflow rad with the in/out ports in the upper left and lower right that should work well with the Cummins. Part #2001-1705


One 3/8" bolt on the upper corners each side and two more on the lower mount each side and the works lifts right out.
