30 Capscrew Markings and Torque Values 24 Valve, 8.3 Liter Engine Page 24 Specifications Capscrew Markings and Torque Values, CAUTION, When replacing capscrews, always use a capscrew of the same measurement and strength as the capscrew being replaced. Using the wrong capscrews can result in engine damage. Metric capscrews and nuts are identified by the grade number stamped on the head of the capscrew or on the surface of the nuts. Customary capscrews are identified by radial lines stamped on the head of the capscrew. The following examples indicate how capscrews are identified: NOTES: Always use the torque values listed in the following tables when specific torque values are not available. Do not use the torque values in place of those specified in other sections of this manual. The torque values in the table are based on the use of lubricated threads. When the ft-lb value is less than 10, convert the ft-lb value to in-lb to obtain a better torque with an in-lb torque wrench. Example: 6 ft-lb equals 72 in-lb.
