Timing Belt Replacement

Special Tools Required 

• Holder handle 07JAB-001020B
• Holder attachment, 50 mm, offset 07MAB-PY3010A
• Socket, 19 mm 07JAA-001020A or a commercially available 19 mm socket

1. Remove the timing belt (see Timing Belt Inspection  ).
2. Clean the timing belt pulleys, and the upper and lower covers.
3. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the timing belt drive pulley with the pointer (B) on the oil pump.
