Head Bolt Torque


Deere 1

Recommended Posts

Can someone tell me the torque spec and pattern for the head bolts on a 1990 Ch613 with a 300 Mack in it?

Thanks, Lee

Here are the torque specs from the Mack E7 service manual.

Torque all head mounting capscrews in three stages to the specified torque.

Torque all head mounting capscrews in sequence to 50 lb-ft (68 N•m).

Torque all head mounting capscrews in sequence to 125 lb-ft (170 N•m).

Torque all head mounting capscrews in sequence to final torque value of 205 lb-ft (278 N•m).
