- Set crankshaft to Cylinder 1 Top Dead Center (TDC) marks by turning crankshaft, in direction of engine rotation, using vibration damper mounting bolt:
Vehicles with manual transmission (engine installed)
The timing mark on the pressure plate (triangular tooth) must align with the reference point on the clutch housing.
Vehicles with manual transmission (engine removed)
The TDC mark milled in the flywheel must align with the reference point -arrow- cast on the flange.
Vehicles with automatic transmission (engine installed)
CAUTION:
- The torque converter has three Cylinder 1 TDC marks -arrow-, as the hole pattern for mounting the torque converter allows it to be fitted in three different positions.
- It is absolutely necessary to verify Cylinder 1 TDC by checking piston position through the spark plug hole.
- If necessary turn the crankshaft by 120° or 240° in direction of engine rotation.
Vehicles with automatic transmission (engine removed)
The mark milled in the drive plate must align with the reference point -arrow- cast on the flange.
