    Orthographic and Isometric Projection's are a way of drawing an 3D object from different directions in 2D. Usually a front, side and top view are drawn so that a person looking at the drawing can see all the important sides. Orthographic drawings are more useful then Isometric as they are a global standard for manufacturing and Engineering this PDF booklet explains in depth how to make a Orthographic Projection's

Inspection Report 004764 The vehicle had a timing chain kit replaced under warranty at xxxxxxx Holden in June 2019, the vehicle’s engine warning has reappeared and a mechanic scanned the ECU and stated to the owner that the timing chain was stretched and faulty and was the cause of the engine warning message. The owner has commissioned this report to have the timing chain kit replaced again at no cost from the Holden dealer as it is now out of vehicle warranty. INSPECTION DETAILS On the 17th of July 2020 the vehicle Holden Commodore VE V6 was inspected by Mark Dewhurst, the ECU was scanned using a GScan2 to find DTC codes in both ECU and EBCM The EBCM was scanned first as the vehicle was not being inspected for a brake fault or had any brake faults messages on the dash LCD, the fault was C0561 an invalid CAN-Bus data code This type of code can be from many reasons from Low voltage at some point to any number of modules that communicate through the CAN-Bus system disrupting the data exchange, code saved and cleared to find didn’t return. Engine ECU scanned to find 2 faults P2176 and P0335, P2176 relates to the Throttle body position not learned, code saved and cleared and then as this procedure can be completed by this scanner a relearn was completed and a successful response received from the ECU, after rescanning found DTC returned possibly faulty throttle body P0335 relates to Crankshaft Position sensor malfunction as determined by the ECU, code saved and cleared and didn’t return. An inspection of the ECU live data shows that the engine rpm was correct at time of inspection and that the timing coalition angle was within .2 degrees meaning the ECU had determined that the timing chain was not faulty, stretched and was correct. There was also no audible sound of the timing chain noise at engine start up or while it was idling Attached Items Conclusion The vehicle has no evidence of chain failure or cam timing being incorrect and the fault codes are most likely due to a faulty crank sensor and throttle body fault. This is from evidence from the scanner connected to the vehicle and expert opinion as the vehicle’s engine was not dismantled to check the timing chain tension and free length or the timing marks.

    Is your bull bar legal? Bull bars used in NSW must comply with the Technical Specification: Requirements for vehicle frontal protection systems fitted to light vehicles (PDF, 2.1Mb) Reference to this Technical Specification is now included in Schedule Two of the Road Transport (Vehicle Registration) Regulation 2017 creating a clear and ongoing regulatory framework for the safe use of bull bars in NSW. Clear requirements for safe bull bar use in NSW From 16 September, the Technical Specification (previously referred to as Bull Bar Tolerances and Conditions) will continue to provide clear and consistent guidance to motorists and industry stakeholders to help ensure that any bull bar that they purchase, sell, install or manufacture for sale is permitted under NSW regulations. The Technical Specification will also ensure vehicles meet other applicable standards affected by the bull bar, such as ground clearance, width, obscured lights and number plates, and the driver’s view of the road. There are no major changes This Technical Specification replaces, on an ongoing basis, previous requirements that have been in place since 2014 under a series of Ministerial Exemption Orders. It will be ‘business as usual’ as making the Technical Specification permanent does not result in material changes for motorists and industry stakeholders. Please note a bull bar is a type of Vehicle Frontal Protection System (VFPS). VFPS is the term used in the Regulation to encompass bull bars, nudge bars and similar devices fitted to the front of a vehicle. The main requirements contained in the Technical Specification are summarised in Is your bull bar legal? (PDF, 906Kb)
