APPENDIX F
TORQUE LIMITS
APPENDIX OVERVIEW
This appendix provides general torque limits for screws used on the M88A1 Recovery Vehicle. Special torque limits are
indicated in the maintenance procedures for applicable components. The general torque limits given in this appendix
shall be used when specific torque limits are not indicated in the maintenance procedure. These general torque limits
cannot be applied to screws that retain rubber components. The rubber components will be damaged before the correct
torque limit is reached. If a special torque limit is not given in the maintenance instructions, tighten the screw or nut until
it touches metal, then tighten it 1 more turn.

TORQUE LIMITS
Table F-1 lists dry torque limits. Dry torque limits are used on screws that do not have lubricants applied to the threads.
Table F-2 lists wet torque limits. Wet torque limits are used on screws that have high-pressure lubricants applied to the
threads.
F-2
HOW TO USE TORQUE TABLE
1
Measure the diameter (dia.) of the screw you are installing.
2
Count the number of threads per 1 inch (in.) (25.4 millimeters [mrm] ) or use a pitch gage.
