I do have another question... was there a snap ring on the pilot bearing? Im asking because if it was there but shouldnt be and the trans mounted would push the crankshaft forward putting excess pressure on the front thrust bearing causing that wear? I almost made that mistake in an Int. 8100 . I put a clutch in it, but couldnt get the trans to mate up, by 1/8". Somehow i figured out the snapring i left on the bearing was the issue. Removed it, seated the bearing.... good to go....

Nice.... I like this posting. I am learning things from you. I am pretty weak with the engine you have, i say that because I have only built 1, 673. I studied my book hard. But, of course E-7 + E-Techs are what I know fairly well. I have seen many similarities in how the engines were designed, of course the E-Tech block is its own kind.. Thanks Freightrain... Jojo

It looks like the crankshaft did not get scratched by the thrust bearing, judging by the condition of the thrust bearing friction surface. Are there oiling grooves in the new thrust bearings ?
-
Yep.. it's worn and does not move when new. Im guessing its worn on the side that takes the force of releasing the clutch. Does the fork push the throwout bearing? Once again, just curious..
-
Paul.. The single leaf spring at the rear of the main box was used here as well. Ive seen it in Ford's and Freightliner's, I think Int.'s also.

Oil leaking from my bottom manifold bolts E7-AMI370

Awesome... -
I see the inspection cover is on top, on the trans. Where is it on the new bell housing? Just curious...

Can you peel back the loom on those wires and write down the code on them? They should start with EJ or VJ, then a number, then a space and then a pair of numbers, then a space, then a decimal number. This code will tell you which ECU, the plug , and the pin number, then you can look at the V-Mac3 book to find that circuits purpose. I have posted the charts before.

Loosen 2 or 3 lines at the head and pump the primer till they bleed, tighten back down 25 lbft,, and fire it up. Foot to the floor and rev it up to clear it out.. -
I saw a report on Fox today where the firefighters were told to stand down for an hour plus in some areas.. then a fire that was put out, was not tended too and it cranked back up and caused a lot of destruction.. The report also sid the reseviors are still empty....
-
Ok..... that adds more info.. do you have other issues?
-
Ok... its 2 wires in 1/4" loom running down the left side radiator and may be coiled up and zip tied out of the way.
-
The A.A.T.S. is where fjh said, there is a thin bracket with a 1/2" hole. It clips in the hole. I forget, but I think its on the bottom left radiator frame area..
-
Good deal. The ground bolt in front of the starter is notorious for comming loose. When you take the eyelets off, scrape the heat shrink glue offbof them. You may want to look at the procedures for a 9-2 code.. I have posted it before, so maybey search it out on here...
-
In addition to fjh's procedures, can you carefully unplug the engine positon sensor while its running, and see if it shuts down, also do the same at the RPM TDC sensor in the flywheel housing. If you un plug one and the engine shuts down, check the other sensor and its wires for damage. A common issue is at the RPM TDC sensor wires. Many times i have found damaged wires inside the loom, if the loom is even still there, also, found weak contact inside the plugs.

Bob... I just re-read my reaction to your post about .003".. I think I came off as a smarta$$.... Sorry about that, I was complimenting freightrains ability, and not trying to discount you.. 😅
-
Pryor to cleaning the regulator , was air building in 1 tank and not the other even after the 1st tank was filled past 90 PSI?
-
Can you hook shop air to the bottom tank and listen for leaks.. ?
-
Yes Bob. .003" is thinner than paper. Freightrain knows what hes doin and what he's got. There are set limits for a reason. But this engine was running without blowby under the heads, so as he said, it will run again...
-
I thought the same thing Bob.. 🍻
-
Exactly!!! Fjh
-
Yes sir... My knowledge is only what Mack taught me. I Have only built stock Mack engines by the book. I have not ever colored outside the lines.. With that said, even though my engines STAY running... I wish I knew how to make small changes to improve performance..
-
Good points as usual, fjh.. it was running.
-
Just curious. I dont have my book in front of me, how would that affect the height of the piston at TDC? Seems to me you would have a bit more compression, but not be too close to the valves.
