PREPARATION FOR OVERHAUL
1. Clean all dirt, mud, dust and foreign
material from the engine before the
engine is removed and disassembled.
2. To ensure that you can perform the
work cleanly and efficiently, check that
you have the proper tools and cleaning
equipment before commencing engine
removal and disassembly.
3. During engine disassembly, as parts are
disassembled, clean them and place
them in trays in their order of disassem-
bly. This will speed up assembly and
help ensure that all parts are correctly
reinstalled.
NOTE:
When disassembling the engine, keep
mated parts together, e.g., cylinder and pis-
ton and other parts that have been "mated"
through normal wear. Mated sets should be
re-used on reassembly, or replaced com-
plete.
