Just like anything else, wash and bake.

New bearings and seals for the center sections . . .

I reckon I'll start reassembling the "group" tomorrow, God willing. :)

Started fitting the turbo group . . .

Still got lots of little details to address. :/

Taking this opportunity to remake the down-pipe to bell-housing mount. I forgot about it when I switched to the lock-up trans and had to cut the thing off, dang-it. :?

Got a little more done tonight:
- The Primary pressure sensor assembly installed. The IP's AFC reference signal is from the Tee-fitting to the right.

Image



- The Secondary pressure sensor installed.
- The turbo lube-oil manifold. It's -8AN fed and in turn feeds the turbos via -4AN lines.
- The waste-gate actuator assembly.

Made and installed the new down-pipe/bell-housing mount. The thing takes the load of the down-pipe and intermediate-pipe movement off the turbo flanges. ;)

Still pecking at it . . .

- Cab heat plumbing.
- Intake feed-horn cleaned up and fitted.
- High-pressure injector feed-lines.
- DATA-log sensors and the associated wiring harness.
* (Most is just sitting there and easily set aside so as to install the engine with less crap in the way). ;)

I've been dragging my feet getting to correcting/fabbing/crap regarding the turbo oil-drains and the current remote oil-filter location.

So, back when I first installed the triples, I had to relocate the engine lube-oil filter. I made a bracket for the filter-head that was OK but, when I installed it, I found that I had forgotten about that turbo lube-oil drain port on the engine oil pan. DOH! I had to grossly tweak the bracket to have the oil filter clear the one turbo oil drain port in the pan.

Image

Image



With this new build, I have to opportunity and plenty of room to fabricate/fit a new bracket that clears the two oil drain ports in the pan.
The former ugly Bracket:

Image



Do some ciphering and make a template:

Image



Transfer that to some 1/8" thick plate-steel, Cut it out and fold it up:

Image



Cut/drill the opening for the filter-head and associated mounting bolts:

Image



Paint and assemble:

Image



Install and shorten/fit the hoses:

Image



The hoses are well away from the hot stuff.

Image



I think it turned out pretty well considering it was made with a jigsaw, anvil, maul and drill. :)

Back when I first built the triple-heap, the lower turbo-group support proved to be less than adequate. It broke. :?

So, I made a new, mo'betta one. ;)

More CAD work:

Image



It fastens to the passenger's upper engine mount bracket:

Image



I drilled and threaded a hole in the engine mount bracket and, using a shoulder-bolt, a couple of small/heavy washers and a jamb-nut, made a pivot-point for the support:

Image



A little more tweaking, cleaning and paint reveals this:

Image


Image



It appears to fit as though it was made to go there and allows room for a turbo lube-oil drain to pass under it:

Image



It easily clears all the stuff behind it:

Image



This version better accommodates thermal expansion/contraction of the heap by allowing the mass to pivot to and from the head without excessive binding:

Image



We'll see, huh?

While waiting for parts:

Back in July of 2016, I rebuilt/renewed the steering on the truck. Such included replacing the steering-box mounting-plate. That removed then was found to be cracked (it was a replacement for the OEM plate that flat broke in two ten years earlier).

Image



Well, anticipating that one (my current) would eventually crack, I got one of those aftermarket, heavy-duty ones a couple of years ago. (https://autofab.com/i-22828661-1972-199 ... acket.html)
The front of the truck's off so . . . I took the opportunity to install the heavy-duty one. It's good that I did so as the current plate was cracked in two spots (all my plate failures have been related to or around the forward-most plate-to-frame bolt).

Image



I can't help but believe the main 3/8" base-plate of the thing somewhat reinforces that section of the truck's frame.

Image


Image



We'll see, huh?

While waiting on parts, I went ahead and disassembled and by way of the ultrasonic cleaner, cleaned the injector components. I'll reassemble and confirm/adjust the pop-pressure directly.

Image



Clean up in there!

Image



This old fella's been of good service all things considered.

Image



I reckon I'll get to them soon enough . . .

The donor engine included its stock/OEM turbo lube-oil drain pipe. I got to looking at it and couldn't help but see the big difference in the working internal diameter of the flange/fitting. The typical "Billet" Aluminum fitting on the left, stock/OEM on the right.

Image



At least one of my primaries was having an issue with lube-oil getting into the compressor. In addition to those narrow drain flanges, I'd committed the sin of tying two turbo drains together. Yeah, I know.

I "Tweaked" that OEM drain-tube to fit the bottom primary.

Image

Image



I may have to pull it up closer to the turbo, as it comes out of the turbo. :?

I've got a couple more 1/2" steel T3 lube-oil drain flanges. That and some 3/4" EMT should take care of the remaining turbos.

Image



We'll see, huh?
