PREPARATION FOR THE
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 clean-
ly and efficiently, check that you have the prop-
er tools and cleaning equipment before com-
mencing engine removal and disassembly.
3. During engine disassembly, as parts are disas-
sembled, clean them and place them in trays in
their order of disassembly. This will speed up
assembly and help ensure that all parts are cor-
rectly reinstalled.
NOTE :
When disassembling the engine, keep mated parts
together, e.g., cylinder and piston and other parts
that have been 'mated' through normal wear. Mated
sets should be re-used on reassembly, or replaced
complete.
