|#846 - Cummins Swap
|Author: andy1canada (Show all albums)
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.
Time to stuff it back in there...
Turbo boost probe installed. This was so easy as the 12-valve already had a brass plug in the intake that once removed allowed the boost probe to screw right in there.
EGT probe installed.
Pacbrake part #C40127 MAX-FLOW 4". This bolts directly to the HX-35 after you remove the 3" stock outlet plate. She'll breath easier now with lower EGT's and improved power and fuel economy.
New Pacbrake installed. This little beauty killed 2-birds with one stone for me. Upgraded my turbo exhaust outlet to 4" and provided me with the best exhaust brake available (IMHO) which, if all goes according to plan, should reduce service brake use by about 80%.
Hot pressure wash/degrease and a couple of coats of engine paint and she's ready to go back in final.
Have to take a moment to praise my idea to use my 3-ton floor jack as my heavy-lift buddy on this work. The interchangeable lift-foot is mounted on a 2" dia. post that sticks up a few inches. I took a 2" forstner bit and bored it about 3" deep into this 6 by 6 block. Had one ready with a 2' by 2' pc of plywood screwed onto it also. Turned out to be real handy.
Fan belt: Gates K080680HD OD=68.625" (68 5/8")
This shows the re-routing of the belt from the standard Ram Cummins setup. NOTE: This is with NO - AC on the engine! Again: Thus far it seems to work with the couple of very short engine runs I've done. I still need to verify function with extended runtime.
Spacer & fan installed. Mind the torque specs on the fan bolts.
