E7 454 in frame rebuild

[Elitedownunder]

Hi,

Does anyone have a 1994 E7 454 workshop manual? I have spun a bearing on the conrod and the crank needs to come out to be reground.....questions are:

Do I have to split the T2180 box which means taking out mount bolts all round?

Does the radiator need to come out to remove the front harmonic balancer, and does this mean the timing gear has to be removed? Also I will have to line the timing before I remove anything,

I wasn't going to remove the heads either?

Anyway any feed back would be great especially if anyone has a manual.

Thanks

Just a suggestion, from your questions you should seriously consider having a professional Mack mechanic do the work. The work you are talking about is not a small fix.

Yes the trans needs split, Balancer comes off, gear removed, Rad removed more than likely, timing marks need to match. Then what about all the metal that is still in all your oil passages, cam bearings?

Sounds like you need some real help.Yes the rad will come out before you pull the engine but good thing is the trans will stay in frame hanging on its mounts.

It is a lot of work. You will have to pull the head so as to pull the piston to change the rod. I would not use the rod that had the spun bearing. I have done cats with the block in the truck. You have to know how to do that. Have all six rods journals cut the same and get six over sized bearings instead of trying to remember which one was cut.

Thanks guys and keep them coming I appreciate all of this......I think I will pull it from the truck and do it on a bench and send out the crank and check the piston and liners, its hard when no money and we are living in Australian outback 100 of miles from anywhere.
