1 Unit 856 Stripping and rebuilding motorsport vehicles (precompetition) UAN: T/600/5970 Level: Level 2 Credit value: 14 GLH: 64 Relationship to NOS: This unit has been derived from national occupational standard Performing Engineering Operations Unit No. 56: Stripping and rebuilding motorsport vehicles (pre-competition) (Suite 2). Endorsement by a This unit is endorsed by SEMTA. sector or regulatory body: Aim: This unit covers the skills and knowledge needed to prove the competences required to prepare a motorsport vehicle, in a recognised sequence and to a high standard, prior to a competition. It will prepare the learner 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 competencies in the working environment. The activities will involve the dismantling and removal of components, inspection and checking for faults and excessive wear and potential problems, replacement of components, and rebuilding the vehicles using hand tools, specialist tools and test equipment, in accordance with approved procedures. It covers motorsport vehicles such as single seat, rally cars, sports cars, karts, historic vehicles, motor cycles and other specific approved competition vehicles, and covers a range of equipment such as chassis and suspension, engine and transmission, steering and wheel braking systems, fuel and lubrication, electrical and other specific equipment. The preparation activities will include carrying out all necessary safety activities to City & Guilds Level 3 NVQ Extended Diploma in Engineering Technical Support (1786) 379

2 lift and support the vehicle and its components, lifting and removing engine and transmission systems, breaking into hydraulic and fuel system circuits, removing springs under compression, removing and replacing faulty equipment at component or unit level, replenishing fluids, and setting and adjusting the completed system in readiness for testing. The learner 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 vehicle within the team s guidelines. The learner s responsibilities will require them 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. The learner will be expected to work with either a high level of supervision or as a member of a team. Where team working is involved, the learner 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, the learner must show that they can competently clean the work area that they are responsible for, including tidying up bays or garages to a standard that will reflect the professional image of the team. The learner must show that they can use and maintain the tools and equipment needed for the dismantling and inspection activities, and return them to their recognised storage area ready for further use. The learner s knowledge will provide an understanding of their work, and will enable them to apply the appropriate dismantling, inspection and rebuilding procedures safely. The learner 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 removal and replacement activities, correct faults and ensure that the equipment is replaced to the required standard. The learner will also have sufficient 380 City & Guilds Level 3 NVQ Extended Diploma in Engineering Technical Support (1786)
