Wiring conduit details on belly pan Buses?

awesome chassis by Jeff !
here are some personal thoughts. Don't know whether true or not.
I believe the rear tube end should just extent inside the angled frame reinforcement,no?
another thought, of what you posted on the front frame loom routing.
I have that idea of what if they fed the wire loom with the chassis upside down ? gravitiy would help in feeding the wire loom over the rear torsion tube ( would slide under, when chassis is upside down). then it could find its way into the flared tube end. the angled frame reinforcment would guide the loom end down and into the tube. when the loom is pushed further and out of the front of the tube and being upside down it would also help finding its way through the front frame kickup.
I still believe they must have had a wire or similar provided to also pull the loom.

I still wonder how the loom is routed inside the rear kickup and if it goes under or over the torsion bar housing tube. and how in the world would it be fed in the loom tubing even with a flare. it is difficult enough to feed a leading wire and the loom on a bus without bellypans. When I built my (belly pan) chassis I put a 2mm steel wire in while building the rails, so I can later pull the wire loom. I wonder if they had somehting similar in Wolfsburg.

Wiring Loom route detail, front

Schematic on how I think the loom/tube sits:

I'm guessing the naked loom just sits on the bottom of the arch there.

Just to confirm my Feb 55 Deluxe has the loom tube.

Here is an original loom tube as seen on the June 1953 Greek School Bus (a Deluxe).
Picture is looking forwards towards the front right jackpoint area.

The tube sits up high in the rhs chassis rail.
Because of this location (as well as being covered by the belly pans), it is very rarely photographed.

Looks like the wiring tabs are still there, but unused.
Utilised for a naked harness, but redundant when the solid tube is fitted.

A theory as to why only the rear of the tube is flared is that the loom is threaded through from the rear, and the softer flaring will not cut into the loom.

Can someone post a pic of where the loom would enter and exit the tube.
Thanks.

JFYI guys, the 22x1mm (20mm ID) tubing is the same size as the original shift rods. it is still easily available in Europe.

Dug it out.
a couple shots and some specs on a sheet. not super accurate but close enough to get the idea.

I use our(USA) 3/4" galvanized electrical conduit when I make them. Its slightly larger in diameter and a tiny bit thicker but does the job.

The original I have has quite a bend/kink in it , this is how it was when I removed it from the chassis. I didnt find it necessary to have that great of a bend to the ones I have installed. Basically just bend enough to follow the frame rails as they transition front to rear.
The flare is at the rear of the bus.

All belly pan buses had the conduit. The '52 Deluxe I'm working on now does, so I'm pretty sure it started from the beginning. It looks just like the above pictures... Just a straight piece of tube running barely past the frame close outs at each end and tacked there. Then a tab in the middle tacked to the frame and the tube to keep it from rattling. I think the original tubing size was like 3/4" or 20mm. If I have to replace it I've used a little larger size tubing as some new wiring harnesses can be tight going through.

it looks pretty evident to me that the welding on the crossmember is not original, so I would be suspect of the belly pans and/or wiring originality.

every belly pan bus Ive seen taken apart had the conduit

Do we really think the factory would install the main wiring harness in a BARE METAL bus before welding the floor or belly pans on?? We know they were dipped in primer...I doubt that was done with the wiring harness in place?

….and a couple of photos from the bullikartei forum.

So, does this exist on all belly pan buses? or introduced in a certain year? or??

Seems I'm not alone in this quest:

one from the gallery ………

"1957 Euro Deluxe main wiring harness
Here are some pictures of the main wiring harness as it travels from front to back. There is a large tab that wraps pretty firmly around the wire bundle near the middle of the right side frame rail.
Here is the main harness exiting the covered channel in the right side frame rail just behind the front crossmember.
Note there is no tube as some have suggested."
