Does anyone have the procedure and specifications for setting valve lash on a 2000 E7-427 in a CX613 (Vision)? I have done this on Cats and Cummins but never a Mack. Thanks.

I do not have my book here tonight but intakes 16, exhaust 24. I believe the E7's have timing marks on the flywheel but it takes two and I was often alone and use companion cylinder method. Write done the firing order. 1 5 3 6 2 4. Then under that write down 6 2 4 1 5 3. Rock the valves on 1 ( exhaust closing and intake opening ) and adjust the valves on 6, draw a line through 6. Then rock 5 and adjust 2, etc. You can start anywhere as long as you keep up with it.
If no one else answers and you want by the book let me know but it will be tomorrow.brian991219 Thanks this. -

No problem only 7 and a half pages.
The first 4 tell you there is a pointer in the center of the hole, at the bottom of the flywheel housing, after you remove the cover. Tool # J38587-A is used in the flywheel housing hole at the right rear of the oil pan to rotate the engine. The flywheels were marked at four places TC, valves 1&6, 3&4, 2&5. If you cannot read them there are instructions on here to remark them if you have a typical flywheel. If you have a non-typical flywheel it should be replaced.
Then use the marks and adjust the valves the same as I explained in the companion cylinder method.brian991219 Thanks this. -
