TORQUE WRENCH

Function and technical context

A torque wrench is an essential precision tool in the maintenance and repair of marine engines, as it allows you to apply an exact tightening torque on screws, nuts and studs of critical elements such as cylinder heads, timing covers, engine mounts and drive train components. Its use guarantees that each fastening remains within the tolerances specified by the manufacturer, avoiding both loosening due to marine vibration and overtorque that can cause thread stripping or joint deformation. In an environment as demanding as the nautical environment, where corrosion, thermal expansion and constant vibrations subject each joint to stresses greater than those of a land engine, having the appropriate tool to perform controlled tightening is essential for the safety and durability of the boat. The reference CRA944595 corresponds to a torque wrench for professional use aimed at maintenance work on outboard, inboard and stationary marine engines.

When to replace or check this tool?

A torque wrench can go out of calibration with continued use, accidental knocks or improper storage, causing erroneous readings that go unnoticed and can lead to under- or overtightening with serious consequences on engine components. It is recommended to verify the calibration of the tool approximately every 5,000 use cycles or, at least, once a season before undertaking preventive maintenance work; If the key has suffered any impact, the check must be carried out immediately. Having a torque wrench in perfect calibration condition is the best guarantee to carry out seasonal inspections with technical rigor and avoid costly breakdowns due to failures in the threaded joints.
