Hello guys, new to this BB, usually over on the Cat BB's Am looking for the torques for the rods and mains, also rod and main bearing clearances and the cylinder head torque. If someone could provide this info for me i would appreciate it. I thought that i had this info but can't seem to find it I could go by bolt size but would rather go by JD specs. Thank you, Don
