Overview

This standard identifies the competences you need to carry out the removal and refitting of transmissions to motorsport vehicles and ancillary components such as pumps, oil coolers, heat exchangers, suspension mountings, oil tanks, flexible and rigid pipework, gear rods, gear and belt drives, control cables and `lifed' components, in accordance with approved procedures.

It covers a range of motorsport vehicles such as single seater, rallying, sports cars, karts, historic vehicles and other specific approved competition vehicles. The removal and refitting methods and techniques will include dismantling the equipment to sub-assembly and component level, protecting exposed components, checking components for serviceability, making mechanical and electrical connections, setting, aligning and adjusting refitted components, tightening fasteners to the required torque, and replenishing oils, greases and fluids.

On completion of the removal and refitting activities you will be required to carry out a range of final checks, tests and adjustments, such as checking gear change, oil and hydraulic fluid leaks, starting and running the engine to ensure that the transmission meets the required specification.

Your responsibilities will require you to comply with organisational policy and procedures for the removal and refitting activities undertaken, and to report any problems with these activities that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment and materials used are correctly accounted for on completion of the activities, and that all necessary job/task documentation is completed accurately and legibly.

You will be expected to work as a member of a team, with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. Where team working is involved, you must demonstrate a significant personal contribution during the team activities in order to satisfy the requirements of the standard, and competence in all the areas required by the standard must be demonstrated.

Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying the appropriate removal and refitting techniques and procedures to motorsport vehicle transmissions and ancillary components. You will understand the removal and refitting methods and procedures, and their application. You will know how the equipment functions, the common problems that can occur, the purpose of the individual components and associated defects, in adequate depth to provide a sound basis for carrying out the removal and refitting activities, correcting faults and ensuring that the equipment is replaced to the required standard. You will also have sufficient knowledge of these components to ensure that they are fit for purpose and meet the specifications, thus providing a sound basis for carrying out the refitting activities.

You will understand the safety precautions required when working on motorsport vehicles, especially those for isolating the equipment. You will be required to demonstrate safe working practices throughout, and will understand your responsibility for taking the necessary safeguards to protect yourself and others in the workplace.
