I still havent seen where he removed the whole seal assemblies. The inner and outer seal with the snap rings that at the flat spring steel type that you remove with a pocket screwdriver. the top dirt seal is not for high pressure. Unless I missed something in the story. If so.. forgive me.
-
Dammit Man... i wish i still had my extra parts. I sent them back with the engine i built. I dont have the part numbers
-
The wear ring + seal is a differnt part number than without the ring. Hope the Mack parts guy gets the right one. I think the number is in the KSA&A book.
-
The rear main seal may offer 2 options. 1 without a wear ring and 1 with a wear ring. The seal itself is different. Just FYI
-
I forgot to add that the fuel pressure regulator is the 45 degree fitting that i said you can 'T' into... if the fuel pressure is low, towards 60 or less and you are not making oil do to fuel dilution, then you need to replace that regulator... then go from there with road tests...
-
60-80 PSI. it used to be 100, but that pressure was blowing out the orings. That plug may fight you, but it is directly in to the fuel gallery.
-
There is a 1/4" pipe plug behind the overboard breather. You can tie in there, if the plug wants to come out, or you can 'T' into line going in to the block below the #4 cylinder...

I have posted the ''pin-out'' charts in case you need to I.D. the circuits. I also posted the 9-2 code info to use to guide you through checking the grounds.

luv it !! fjh

The Cal Codes are important, but the engine will run good until it learns how its running. Not entering the Cal Codes is not the issue here..

Just go back a few pages. He posted pictures

His front crankshaft thrust bearing was damaged. So we started chatting about the forward forces on the crank that would have damaged the thrust bearing.. I even doubted myself when I knew I was right about my Boo Boo doing that job.. I guess I need another shot of Potato Juice. 🍻
-
Yep.. I just realized i was too quick to doubt myself.. I did a do over on my math..
-
Oops. Your right, I just did the math.... 🙃
-
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.

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.
