• Page 8: About The Manual

  Additionally the manual is intended to aid mechanics in disassembly, inspecting parts for reuse, rebuilding and assembly of components. The manual is divided into sections. Each section is equivalent to a group used in Cummins' filmcard system. Some sections contain reference numbers and procedure numbers. Reference numbers provide general information, specifications, diagrams, and service tools where applicable.

• Page 9: How To Use The Manual

  How to Use the Manual General Information This manual is divided into the same group system used for previous manuals and the Cummins' filmcard system. Section 00 is organized into a logical sequence of engine disassemble/assemble, all other sections are in numerical sequence.

  The assembly instructions have been written to use again as many components and assemblies as possible. When it is necessary to replace a component or assembly, the procedure is based on the use of new Cummins or Cummins ReCon® components. All of the repair services described in this manual are available from all Cummins Distributors and most Dealer locations.

• Page 19: General Cleaning Instructions

  Cummins Inc. does not recommend sanding or grinding the carbon ring at the top of cylinder liners until clean metal is visible. The liner will be ruined and any signs of a problem at the top ring reversal point (like a dust-out) will be destroyed.

• Page 20: Gasket Surfaces

  The object of cleaning gasket surfaces is to remove any gasket material, not refinish the gasket surface of the part. Cummins Inc. does not recommend any specific brand of liquid gasket remover. If a liquid gasket remover is used, check the directions to make sure the material being cleaned will not be harmed.

• Page 21: Plastic Bead Cleaning

  Plastic Bead Cleaning Cummins Inc. does not recommend the use of glass bead blast or walnut shell media on any engine part. Cummins Inc. recommends using only plastic bead media, Part Number 3822735 or equivalent on any engine part. Never use sand as a blast media to clean engine parts.

• Page 22: Fuel System

  Cummins Inc. now recommends glass bead media NOT used to clean any engine parts. Glass media is too easily embedded into the material particularly in soft materials and when air pressures greater than media manufacturer's recommend are used.
• Page 23 Clean and dry the tools before returning them to the tool box. • If possible, store fuel system tools in sealed containers. • Make sure fuel system tools are clean before use.
