URN: SEMPEO260
Business Sectors (Suites): Performing Engineering Operations Suite 2
Developed by: Enginuity
Approved on: 30 Mar 2017

Overview

This standard identifies the basic competences that you need to re-build a motorsport engine in a recognised sequence and to a high standard, prior to a competition. It will prepare you for entry into the motorsport sector, creating a progression between education and employment, or it will provide a basis for the development of additional skills and occupational competences in the working environment.

The activities will involve the dismantling and removal of components, inspection and checking for faults, excessive wear and potential problems, replacement of components, and rebuilding the engine using hand tools, specialist tools and test equipment, in accordance with approved procedures. It covers motorsport engines fitted into motorsport vehicles such as single seater, rally cars, sports cars, karts, historic vehicles, motorcycles and other specific approved competition vehicles.

The stripping and re-building activities will include carrying out all necessary safety activities, to lift and support the engine and its ancillary components. You will need to lift and remove the engine from any transportation containers and place it onto an approved holding device, ready for removing all ancillary components and the stripping and rebuilding of the engine. You will need to ensure that all removed components are stored safely, prior to inspection and re-building. You will also be expected to use recognised methods for crack testing ferrous and non-ferrous materials/components, and to be able to inspect a motorsport engine within the team's or organisation's guidelines.

Your responsibilities will require you to comply with recognised procedures for the stripping and rebuilding activities undertaken, to take account of any potential difficulties or problems that may arise, and to seek appropriate help and advice in determining and implementing a suitable solution. You will be expected to work with either a high level of supervision or as a member of a team. 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.

On completion of the activities, you must show that you can competently clean the work area that you are responsible for, including tidying up bays or garages to a standard that will reflect the professional image of the team. You must show that you can use and maintain the tools and equipment needed for the stripping and rebuilding activities, and return them to their recognised storage area ready for further use.

Your underpinning knowledge will be sufficient to provide a broad understanding of your work, and will enable you to apply the appropriate stripping, inspection and rebuilding procedures. You will know how the equipment functions, the common faults that can occur, the purpose of the individual components and associated defects, in adequate depth to carry out the stripping and rebuilding activities, correct faults and to ensure 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.

You will understand the safety precautions required when carrying out the stripping and rebuilding activities, especially those for lifting and supporting 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.

Knowledge and Understanding

You need to know and understand:

  1. the specific safety practices and procedures that you need to observe when stripping and rebuilding motorsport engines and when using lubricants and fluids (including lifting and handling techniques; safe working practices with regard to dismantling motorsport vehicles; procedures which satisfy current regulations - such as HASAWA, COSHH, PUWER and other related legislation and guidelines)
  2. the hazards associated with stripping and re-building motorsport engine components, and with the tools and equipment used (such as the safe support of the engine at the correct working height and position, the safe release of fuel and other liquids, misuse of tools), and how they can be minimised
  3. the protective equipment that you need to use for both personal protection (PPE) and protection of the engine
  4. the importance of good housekeeping within the working area (such as leaving the work area free of debris and used materials, cleaning and maintaining tools and equipment, returning equipment to designated storage area, leaving the work area in a safe and tidy condition), and of good personal presentation to ensure quality representation of the team or organisation
  5. preparations to be carried out on the engine (such as removing transportation containers, cleaning away dirt, dust, oil or track debris; making visual checks of the systems and components for obvious signs of damage or excessive wear - such as leaking coolant or oil, chafing, cracks, excessive clearances; ensuring suitable storage space is readied once the systems have been removed from the engine and providing suitable containers for the storage of fasteners and other small components)
  6. how to use and extract information from motorsport engine building documentation (such as engine manuals, system diagrams, engineering drawings, engineer's records)
  7. the importance of ensuring that you use the correct and up-to-date documentation
  8. the techniques used to remove components from motorsport engines without damage to the components or surrounding systems (such as release of spring pressures/force, draining of fluids, proof marking, extraction of components and the need to protect the system integrity by fitting blanking plugs to exposed pipes)
  9. how to use a range of hand tools (such as spanners, sockets, screwdrivers, punches, drifts) to remove a range of components (such as studs, pins, circlips, seals and gaskets, bearings, gears), and how to use release agents to help free joined parts where seizure or damage may have occurred
  10. the various mechanical fasteners to be removed and replaced, and their method of removal and replacement (such as threaded fasteners, special securing devices)
  11. the various types of electrical connectors that are used, methods of unlocking, orientation indicators and locating and locking-in of connections
  12. methods of lifting, handling and supporting the components/equipment during the stripping and re-building activities
  13. methods of checking the components for damage or wear (using visual methods, measurements, and crack detection techniques)
  14. the need to use new components where checks during stripping revealed such needs; fitting together new or prototype components where a degree of initial fitting may be needed (such as filing, fettling, reaming, tapping, shimming, polishing and adjusting to achieve the required assembly specification); sealing and securing components (such as using nuts, bolts and associated fasteners, rivets, circlips, sealants and locking compounds); checking for correctness of fit and accuracy at critical stages during the rebuild and on completion of the assembly
  15. how to make adjustments to components/assemblies to ensure that they function correctly (such as travel and working clearance, timing and sequence)
  16. why securing devices need to be tightened to the correct torque and locked, and the different methods used
  17. the tools and equipment used in the engine stripping and re-building activities, and their calibration/care and control procedures, and the need to control and account for all tools and equipment used during the stripping and re-building activities
  18. how to deal with problems (such as what to do when components are damaged or worn in some way, the correct equipment or parts not available, components do not come apart as readily as expected)
  19. the recording documentation to be completed for the activities undertaken and, where appropriate, the importance of marking and identifying specific pieces of work in relation to the documentation
  20. the procedure for the safe disposal of waste materials, scrap components, contaminated oil and fuel
  21. when to act on your own initiative and when to seek help and advice from others
  22. the importance of leaving the work area and equipment in a safe and clean condition on completion of the stripping and rebuilding activities (such as returning tools and equipment to the designated location, cleaning the work area, and removing and disposing of waste)
