5-1PREPARATIONS and SUGGESTIONS

1)When disassembling the engine, remember well the locations of individual parts so that they can be reassembled cor- ,-

rectly. If you are uncertain of identifying some parts, itis suggested that tags should be attached to them. 2 ) Have boxes ready to keep disassembled parts by group.

3)To prevent missing and misplacing, temporarily assemble as much as possible each group or set of disassembled small parts suchas bolts and nuts, etc.

4)Carefully handle disassembled parts, and clean them with washing oil.

5)Use the correct tools in the correct way.
