APPENDIX E
GENERAL TORQUE LIMITS REQUIRED FOR FASTENERS IN ENGINE
Section I. INTRODUCTION
E-1. SCOPE
This appendix provides the general torque limits for fasteners used on the 6V53 ModeI 5063-5299,
5063-5392, 5063-5393, 5063-5395, 5063-5398, 5063-539F and 5063-539L engines. Special torque
limits are indicated in the maintenance procedures for applicable components. These general torque
limits cannot be applied to fasteners that retain rubber components. The rubber components will be
damaged before the torque limit is reached.
E-2. TORQUE LIMITS
This appendix lists the dry torque limits. Dry torque limits are used on fasteners that do not have
lubricants applied to the threads. No wet torques are given because all wet torques are listed in the
maintenance procedure. The torques given are suitable for grade 5, 5.1, 7, and 8 fasteners. No grade 1
or 2 fasteners are used on the 6V53 series engines.
E-3. HOW TO USE THE TORQUE TABLE
a. Measure the shaft diameter of the fastener and count the number of threads per inch.
b. Under the heading THREAD SIZE, look down the column until you find the diameter and
per inch of the fastener. Next, look across that row and read the torque limit in Ib-ft or N•m.
