Information:
T-T-T Procedure
A torque-turn-tighten (T-T-T) procedure is used in many specifications and instructions.1. Clean the bolt and nut threads.2. Put lubrication of the threads and the seat face of the bolt and nut.3. Turn the bolt or the nut tight according to the torque specification.4. Put a location mark on the part and on the bolt head or nut.5. Turn the bolt or the nut tighter the amount of degrees according to the specifications The side of a nut or bolt head can be used for reference if a mark can not be put on. Torque Wrench Extension
When a torque wrench extension is used with a torque wrench, the torque indication on the torque wrench will be less than the real torque.
(E) Torque wrench drive axis-to-torque wrench extension drive axis. (W) Mark on handle-to-torque wrench drive axis.1. Put a mark on the handle. Measure the handle from the mark to the axis of the torque wrench drive (W).2. Measure the torque wrench extension from the torque wrench drive to the axis of the torque wrench extension drive (E).3. To get correct torque indication (TI) when the real torque (RT) is known: Example: W = 304.8 mm (12 in); E = 65.0 mm (2.56 in); RT (from specifications) = 17 N m (125 lb ft). 4. Hold the torque wrench handle with the longest finger of the hand over the mark on the handle to get the real torque (RT) with low torque indication (TI) on the torque wrench.Locks
Flat metal locks must be installed properly to be effective. Bend one end of the lock around the edge of the part. Bend the other end against one flat surface of the nut of bolt head.Always install new locks in components which house moving parts.If lockwashers are installed on housings made of aluminum, use a flat washer between the lockwasher and the housing. Lines And Wires
When removing or disconnecting a group of lines or wires, tag each one to assure proper assembly.Lubrication
Where applicable, fill the compartments of the components serviced with the amount, type and grade of lubricant recommended in the Operation Maintenance Manual.Rust Preventive Compound
Clean the rust preventive compound from all machined surfaces of new parts before installing the part.Shims
When shims are removed, tie them together and identify them as to location. Keep shims clean and flat until they are reinstalled.Bearings
Anti-Friction Bearings
When an anti-friction bearing is removed, cover it to keep out dirt and abrasives. Wash the bearings in nonflammable cleaning solution and allow them to drain dry. The bearings may be dried with compressed air, but DO NOT SPIN THE BEARING. Discard the bearings if the races and balls or rollers are pitted, scored or burned. If the bearing is serviceable, coat it with oil and wrap it in clean paper. DO NOT unwrap new bearings until time of installation.The life of an anti-friction bearing will be shortened if not properly lubricated.Double Row, Tapered Roller
Double row, tapered roller bearings are precision fit during manufacture and the components are not interchangeable.
