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, since they are available universally. Failure of structural members of the
tool are quite rare, but replacement parts are available from stock. All repairs to HYTORC tools may be made by
reasonably experienced individuals according to these instructions.
• Lubrication
All moving parts should periodically be coated with a good quality NLGI #2 molybdenum disulde grease. Under
harsh environmental conditions, cleaning and lubricating should be performed more frequently.
• Hydraulic Hoses
Hoses should be checked for cracks and leaks before, and after each job. Hydraulic ttings can become plugged with
dirt and should be ushed periodically.
• Quick-Connects
Fittings should be kept clean and not allowed to be dragged along the ground or oor, 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.
