TM 10-3930-671-24 Critical Fastener Torque Checks Refer to Section 2.1, Service Specifications, for Critical Fastener Torque Chart. View Showing Typical Torque Wrenches. NOTE When practical, always torque the nut while holding bolt stationary. Fasteners in highly loaded (critical) components can quickly fall if they become loosened; also, loose fasteners can cause damage or failure of the components. For safety, it is important that the correct torque be maintained on all critical fasteners of components which directly support, handle, or control the load, and protect the operator. Check torque of critical items, including: • Overhead guard. • Transaxle mounting. • Drive and steer wheel mounting. • Counterweight mounting. • Load backrest extension. • Tilt cylinder mounting and yokes. • Upright mounting and components. • Chain anchors. • Engine mounts.
