This is what the service manual states but is it accurate? I am also working on a 7020 engine (Out of a M2 combine).  ------------- D19D, D17D, WD, WC, Snobee, #83 Plow, SC Blade, 14' disk, 400 series planter, B , Terra Tiger, M Dozer w/Baker Blade, TL-12, 42S Grader, G |

I bought new rod bolts from AGCO. I looked at the head of the bolts and they are stamped with "EMP" and "170M". Here is a post I found from 2015: https://www.allischalmers.com/FORUM/301ci-allis-motor-model-649t_topic102439.html" rel="nofollow - 301CI allis motor model 649T - AllisChalmers Forum ------------- D19D, D17D, WD, WC, Snobee, #83 Plow, SC Blade, 14' disk, 400 series planter, B , Terra Tiger, M Dozer w/Baker Blade, TL-12, 42S Grader, G |

AGCO shop manual states the main bearing cap as being a Grade 8 bolt to be torqued to 135 ft lbs. The conn rod bolts are 3/8-24 , Grade 100, torqued to 45 ft lbs.

This engine, out of a M2 combine, I plan on putting into a 7020. I noticed excessive crank end play so pulled the pan to discover the clutch side of the #4 bearing has the shoulder wiped off of it. What would have caused this? I plan on putting in new main bearings but if the crank is cut wrong or ??, I don't want to throw my money away.  ------------- D19D, D17D, WD, WC, Snobee, #83 Plow, SC Blade, 14' disk, 400 series planter, B , Terra Tiger, M Dozer w/Baker Blade, TL-12, 42S Grader, G |
