The chart shown here stays with the engine for fast and easy reference of service information until the assembly is complete.The Assembly Procedures and Specifications Charts can be used as a work plan. This is a big advantage when two servicemen work together on the assembly of one component and/or when servicemen on different shifts work on the same component.
The charts improve communication between servicemen on different shifts. If each assembly step is checked off as it is completed, the servicemen on the next shift can quickly see what work has been completed and what work is still to be done. This decreases the possibility of an important step not being done, especially an inspection function.
The Assembly Procedures and Specifications Charts can also be used as efficient guides for the disassembly of the basic component.
During disassembly the serviceman can check the chart to see in what step each subassembly and parts (such as hardware) will be used. He then makes a separation of the parts (and components) according to the sequence in which they will be needed.
Groups of charts are hung in different areas of the service shop. Servicemen use the chart nearest to their work for reference.It takes much less time to do the work if the parts are put in groups together as they will be used in the assembly process.
Each chart is a separate publication and has its own form number. When a chart needs revision, a new one takes the place of the out-of-date one. This makes it easy to give the serviceman the most current information. When a revision is made to a chart, a "C" is added to show what was changed.
The charts are designed to be used and kept in the assembly work area. For this reason they are printed on soil-resistant and tear-resistant paper. Oil and dirt can be easily cleaned off the charts.
Dealers that use the Assembly Procedures and Specifications Charts regularly have developed several different methods for the storage
