#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.

Measured the length of the 47RH (4x4 version)from the forward edge of the bell to where the intermediate housing bolts to the t-case: 31 3/8" (+/- 1/8")

Now to ditch the t-case and rebuild this baby.

This is the 47RE. Was my second choice for a trans after I had too much trouble finding a 47RH(A618). But when the one I now have came up for sale here on the Island, I decided to go back to my original plan. The RH is much easier to control and I don't have to drop another $1000.00 or more on a stand-alone controller. The comparable 47RE length measurement - at 26 3/8" from bell to t-case connection - confirms that the RH basically brings 5" additional length to the train.

Six Alcoa's, shiny Alcoa's... charging down the highway in the blazing sun!

Scored a second 47RH at a price I couldn't refuse. So - as seen here in the pic - I'm going to breed them and see if I can make more little ones. The male is the one with the pointy thing :-0

Mondo Inverter 2,000,000/watts!

When I saw Rico's pic of how he blocked up his coach, I liked it right away. Much safer than the way I had it before. The wheels are sitting over a foot off the ground now.

Air-spring trailing arm mount sketch. 3-pcs: 12" x 3 1/2" x 5" angle iron mount, welded to forward flat section perpendicular to torsion bar; 3-ft section main beam; upper bag mount welded to coach chassis. Dimensions to be verified.

I'm running with these Goodyear #2B9-252 airsprings. They're used on heavy trucks and trailers and the specs tell me they are a tad on the large side for this application; but, I scored them for a song so - they are going to fit!

Here ya' go Lenny! I actually took your advise and did a mock-up out of some crap plywood I had kicking around. Used a laser under the coach to spec out the sketch to make sure all clearances were considered and accounted for. The primary material will be 3 1/2" X 5" X 5/16" angle iron. Most of the 3-ft. main-beam section and the 12" long mount section that will be welded to the trailing arm will be made from this; additionally, this mount will be bored for three 1/2" bolts so the main beam can be bolted to it and easily removed if required. So far it's looking good but I've yet to confirm the correct angle to mount/weld the mounting plate at.

This pic shows that with the 3 1/2" x 5" angle mount bracket in play, there actually may be enough room to get at it with a mig to weld it to the trailing arm.
