IDI torque specifications

[EMD_DRIVER]

Every time we fix or replace something on our trucks, they usually always require a certain amount of torque. Could we have a tech article, that contains the torque specifications for everything from glow plugs, to ball joints? I know they are all contained in the service manuals, but I think it would be just as easy to look them up in a tech article, just after someone on here teaches us how to fix whatever we are looking to fix!

Anyone care to list any of the torque specs that they know of, from "The book"?

I will get my manual out tomorrow and post the specifications that it lists.

*Unless otherwise specified, torque values are with threads and washer faces coated with clean engine oil.
Note 1-Apply general purpose Lock N' Seal (IH P/N 577 588 C1) to all threads of bolts prior to assembly.
Note 2-Tighten bolt connecting rod nuts to 51 Nm (38 lbf-ft) before final torque is applied.
Note 3-Cylinder head bolts to be torqued in steps as specified in Figure 3. Final Torque value for new and used bolts is different.
Note 4-Apply "Never Seez" compound (IH P/N 634 227 C1) to threads of bolts prior to assembly, then torque in steps as specified in Figure 6.
Note 5-Intake manifold bolts to be torqued in steps as specified in Figure 6

Note 7-Valve Cover screws to be torqued in sequences as specified in Figure 4.
Note 8-Rotate Engine until timing mark (notch) on vibration damper is approximately 20 degrees before vertical position as viewed from the front of the engine, approximately 11:00, Refer to Figure 8 Tighten each pair of bolts down evenly. Refer to Figure 9
Note 9-Clean bolts thoroughly. Apply liquid gasket (IH P/N 446 839 C1) to designated bolts(refer to figure 7) only

Would probably help if I had the pictures to go along with it

I have to give you credit just for taking the time to type all of that up!

It's a big more complicated than that. 6.9 and 7.3 have some differences. It will need to be in the format....

Item.................................................... 6.9................7.3

Gary's post taken at face value will have some 6.9 owner pulling his heads back off to retrieve the little pieces.

And should we have newton meters for our non-U.S. friends?

How true Mel.. I'm always thinking 7.3 most of the time... Thanks. CDX, you must have the same gray cover manual that I have. Mine is book CGES-435-1. You did a very good job of the posting. Was that scaned in or typed in... I'm impressed...

 

[CDX825]

Yeah forgot to mention thats for the 6.9 Its all from Form CGES-340-2. Its a brown faced manual I got off of ebay. Lots of good info in that book! That was all typed to My brain hurt afterwards

Since I have one of each, I guess I should have been more specific..

That was all typed to My brain hurt afterwards

Great job! My brain would hurt too... Oh, wait.... It already does!

I know this is an ANCIENT thread, but it's the first hit on google when I search for "7.3 IDI Torque Specs" and it doesn't have the link to the better IDI torque spec thread located here:

I just can't stand searching on the internet (with dirty hands) for the specs and not getting the right post, so at least now it will redirect everyone to the better thread.

Also, I have collected all the 7.3 IDI torque specs, as well as the bolt and nut threads and dimensions, and put them in this article: http://www.nickpisca.com/diesel/engine/7-3-idi-torque-specs-and-bolt-dimensions-with-images/
