Heavy Goods Vehicle Inspection: Transmission Mobile App
Core features are free forever
The primary purpose of the Heavy Goods Vehicle Inspection: Transmission
How does it work?
mobile app is to support staff in conducting the annual testing of vehicles. The app is useful to those responsible for the maintenance of large commercial vehicles so that they remain well informed on the current minimum legal standards for roadworthiness. It must be emphasised that these are minimum acceptable standards, which do not necessarily allow for further deterioration when the vehicle is in service.
This inspection applies to all vehicles including Hybrid Electric Vehicles (HEVs) and to trailers with driven axles. Vehicles must be in neutral gear and with any transmission brake released during this inspection. The presenter should be advised if any shaft or carrier locking device is missing or ineffective. Failure for excessive wear of a universal joint is only justified when radial movement indicates that needle roller bearings are missing from one or more cups. Transmission shafts include those shafts that transmit drive for HEVs. Propeller shaft spline wear is not a Reason for Failure. A power take off prop shaft universal joint is not subject to this inspection.
