hope this helps you I just went out in the workshop and looked in my book it says on all majors the rod cap torque should be 55- 60 ft- lbs. if you need any other settings just ask. I will be in and out of the house most of the day and i'll get back to you a.s.a.p

It makes no difference what engine of the Major/590 E range you have, all the torque settings are the same.
It is best to fit new lock nuts rather than use the old ones.
Torque is :
Head .. 85 to 90 ft/lbs
Mains .. 1/2" = 70 to 75 lbs ft, 9/16" 95 to 100 lbs/ft.
B/Ends .. 55 to 60 lbs/ft.
Fly Wheel .. 80 to 90 lbs/ft.
