Learning all sorts of stuff and overcoming one challenge at a time. I love projects... once they're over. Never as easy as it seems or as complicated as you expect, but always learn something along the way. Looks great so far, keep it up!

One thing I've learned: Never ever come out from under the covers of the morning.
Still working on the micky mouse TPS. Called them today and did get an idea of where to drill the hole in the throttle linage to get the whole thing to work. The TPS will need a return spring to make it work.
Took the drive shaft to get it rebuilt today, so things are moving ever so slowly.

I'm still working away on this little project.
Got the drive shaft back and in installed. Cost about 3 times what I expected... Ouch!
Found my long lost parts: shift linkage and converter bolts. Need to replace the bolts I got from Allison... These are longer.
Working on the wiring now..... Well need to be doing that rather then this.

Took all the pumps and fans connectors loose and plugged in the programmer tuner turned on the ignition...... And Nothing! Checked all the plugs. And Nothing. Call the company, "unplug and replug" And Nothing. Call the company back... Now he tells me I need to connect the yellow and white wires for the 'tap shift' that go from the shiftier wire harness to the trannny computer harness. He told me to just cut them off because I wasn't using the 'tap shift' when I talked to him last.

I know this was going to be a goat screw because this system came with NO documentation! Now I need a wiring diagram!

On top of that, the air pump don't shut off, so, need a new air pump!

Still need to take the fuel tubes off and then the inlet apart an put new gaskets to stop the inlet leak that's giving me high EGT.

Good new... I hooked the white and yellow wire together and I think all is working!!!!!!

Now the that pump!!! Wonder what people replace it with. I got a spare from the PO. Was rebuilt in 1991. The phone number on the paper work isn't a working number now.

If we as humanity always did things that made sense there would be no Eiffel Tower, no moon landing, no pyramids and no new world.

Keep going Mel, for when others inevitably follow, may they learn from your mistakes and reap the rewards of your triumph.

Cheers mate
Tony

Jubilee!!
Got the TPS adjusted to work from 0-100% And it's mounted!!!!

While I had the ignition on adjusting it, the air pump (in the far rear corner) for the air ride never shut off. The PO had had the pump replaced in 1991 and had the original rebuild. It's been under the bed every since. So I changed the pump out. Now the book tells of a bank of breaker 'behind the front access door'. BUT! The only breaks there are for house battery and what I've added. Is their another 'front access door' I haven't found?

Where are that????????????????????
(Sorry about the lazy picture)

Now I'm taking the injector fuel lines off to replace the gaskets on the inlet in hopes that that's my inlet air leak which is giving my high EGT on full acceleration.

454 to Cummins

Mel,

Are you chasing an air leak from turbo to intake manifold?

I made an adapter that allowed me to block off and pressurize the system with air at 20 psi or so and listen for and even spray soapy water on hoses, intercooler, etc looking for leak.

Do you have a boost gage?

They are in front on the right after you open your engine latch. They just dont look quite like that picture. Instead of the relay you probably have a battery isolator and the breakers should be to the left of that. Every rig I have seen had a different layout.

I have 35 psi up stream from the inlet heater block. There were bolts missing from the inlet plate, so being I have everything out of the way to get to that gasket, I'm going to replace it. Then put it all back together and carefully spray started fluid around with the engine at an idle.

That's my plan anyway.

Need to get some spring planting done now.

I've never sprayed starting fluid like that, no experience.

Consider swapping that for soapy water?

Remember that system runs on a positive pressure, not vacuum.

I still have my test cap at home from my 12V. I could email you a pic if you want.

At an idle there is a vacuum.... least that's what the 'big boys' tell me.

A picture of your test cap would be helpful. I've got most of the bolts out. Would be a good idea to pressure check if after I get it back together.

May get some time to work on it today, if the weatherman is right and it rains today.

The two breaker above the solenoid was all that was there. The are both house battery. I've added the one under for the cooling fans.

I think every coach was built like it was first ever seen. The way mine is wired looks like every wire was pulled by the new hire of the day.

So, I've been in a fog trying to figure out how/where/how to locate the turban.

On the stock manifold the floor is in the way. With the 'motor home' manifold the engine block is in the way as well as the fitting for the turban oil supply.

I take the stock and start putting spacers between the head and the manifold to see if the manifold can be milled. Can't move the turban down enough to even thing about it.

The turban shop has another exhaust housing with the gate actuater at a different angle that would clear the block (I think). Now the oil fitting, it's metric and NO ONE has metric hoses and fitting.

Motor home oil cooler cover

I look at my 2001 Dodge Cummins and the oil fitting is on the outside hole where the 'pipe threat' plug is on mine.

To the computer I go to 'Cummins quickserice online'. Put in the 2001/1996 engine s/n and compare. They are both the same IPD. The coolers and gasket are the same, the gaskets and covers have different p/n's. I go to Cummins and order the cover and gasket.

Want the old off to take and compare Monday when I pickup the new parts. All the bolts screw right out except the two by the A/C pump. They came out 1/12th of a turn each all the way out. One WAS a stud bolt. Not room to clear the pump, so, saw/saw made it into a bolt

I hope! I hope!

Now the wife has completely commandeered my shop all the way to the side of the motor home with tables for her BIG benefit garage sale this week! I did have path. Now I have none Another chore I have for Monday is to go get more tables. Hope this helps the gal w/MS go to Mexico and either get cured or killed for $70,000.

Converting this to a diesel is nothing but a love affair. With every part I put on, I 'Take It off' to modify till the next part.

I got my turban back today with a different turban exhaust housing with the wastegate actuator pointing in a different direction.

When I get to see the motor home after this benefit sale..... I will keep you posted.

BTW I've push the 454 1/4" stroker motor out and am going to donate it and the 4L80e to the cause of our friend's going to Mexico for MS treatment.
