Preventive Maintenance -
Torque Machines
Tool failure, although rare, does occur. Such failure is most often in the hydraulic couplers or hoses. These items are
repairable or replaceable immediately. Failure of structural members of the tool are quite rare, but replacement parts
are available from stock. All repairs to TORC, LLC. tools may be made by reasonably experienced individuals
according to the aforementioned instructions.
• Lubrication
All moving parts should periodically be coated with a good quality NLGI #2 molybdenum disulfide grease. Under
harsh environmental conditions, cleaning and lubricating should be performed more frequently.
• Hydraulic Hoses
Hoses should be checked for cracks and leaks after each job. Hydraulic fittings can become plugged with dirt and
should be flushed periodically.
• Quick-Connects
Fittings should be kept clean and not allowed to be dragged along the ground or floor, as even small particles of dirt
can cause the internal valves to malfunction.
• Springs
Springs are used for the drive pawl assembly and for the accuracy assurance pawl. These springs can be replaced if
necessary.
• Cylinder Seals
If the cylinder requires disassembly, it is recommended that the cylinder seals be replaced at the same time. Seal kits
are readily available.
• Structural Members
All structural parts on the tool should be inspected once a year to determine if there are any cracks, chips or
deformities. If so, immediate replacement is required.
