Repair Procedures: Disassembly

Information 

• Mark all wiring connector and hoses to avoid misconnection.
• To release the fuel system pressure before removing the engine assembly, start the engine without fuel pump relay. Then, switch "OFF" the ignition when engine stops.
• Turn the crankshaft pulley so that the No. 1 piston is at top dead center.

1. Remove the engine and transaxle assembly.

   (Refer to Engine and Transaxle Assembly - "ENGINE AND TRANSAXLE ASSEMBLY ")

2. Remove the harness clamp from the wiring connector around the engine and transaxle and remove the connector bracket.

    NOTE:

    • Keep the connecting rod and cap with their bearings assembled together.
    • Arrange the piston and connecting rod assemblies in the correct order.
17. Check fit between piston and piston pin.

    Try to move the piston back and forth on the piston pin.

    If any movement is felt, replace the piston and piston pin as a set.

18. Disassemble the piston rings.
    1. Using a piston ring expender, remove the 2 piston rings (A).
    2. Remove the oil ring (B) by hand.
19. Disassemble the connecting rod from the piston.
    1. Remove the snap ring (C) from the piston.
    2. Using a press, remove the piston pin (D) from the piston.
    3. Disassemble the piston (E) and connecting rod (F).
