Timing Belt: Installation

Ensuring all timing marks are aligned. Install belt over one pulley at a time staring at crankshaft sprocket working counterclockwise. Belt should go over tensioner last. Secure belt at each pulley during installation with pinch clips. See Fig 4.
CAUTION: To ensure correct timing belt installation, ensure direction of rotation arrows are pointing in proper direction. If timing belt is being reused, install belt in original direction of rotation.
Compress timing belt tensioner pusher and insert pin to retain pusher. Apply pressure to tensioner against belt and install tensioner pusher. Tighten bolts to specification. See TORQUE SPECIFICATIONS .

Loosen tensioner pulley bolt. Apply pressure on belt by rotating tensioner. Tighten tensioner pulley bolt to specification. Remove pin from timing belt tensioner pusher.
Remove pinch clips from timing belt, (if used). Install crankshaft pulley, tightening center bolt finger tight. Rotate crankshaft 2 turns clockwise. Ensure timing belt tensioner pusher rod protrudes proper amount. See Fig 5.
If timing belt tensioner pusher rod protrusion is not within specification, remove pusher, loosen tensioner pulley bolt and readjust. Reset timing belt tensioner pusher rod and repeat step 3).
Remove crankshaft pulley and install timing belt cover. To complete installation, reverse removal procedure. Tighten nuts and bolts to specification. See TORQUE SPECIFICATIONS .
