CYLINDER BLOCK DISASSEMBLY (II)

Caution
• Placing the crankshaft on a disassembly bench will cause the drive gear to contact the disassembly bench because the crankshaft drive gear is larger than the counterweight. This could result in the drive gear being scratched or damaged which could become a source of noise. Therefore, set wood blocks or similar object on the both sides of the crankshaft or place a thick clean rag under the drive gear so that the drive gear does not contact the disassembly bench directly.
• Parts for engines manufactured in Mexico and Hiroshima cannot be used interchangeably as the engine will not operate correctly resulting in a serious malfunction. To prevent this, when replacing parts refer to the 'SPECIFICATION IDENTIFICATION' table below and verify the engine's place of manufacture before performing the servicing. (See SPECIFICATION IDENTIFICATION)
