Removing
Remove the toothed belt.
Insert a large screwdriver into the technological window in the clutch housing and insert it between the teeth of the flywheel crown, thereby blocking the crankshaft from turning. Having asked an assistant to hold a screwdriver, unscrew the crankshaft drive pulley bolt, remove the washer and pulley.
Remove the toothed belt pulley from the crankshaft. If the pulley key is loose, remove the key.
Installation
Install key (if it was taken).
Lightly grease the key and crankshaft toe. Install the timing belt pulley on the crankshaft and hand-tighten the pulley bolt. Having fixed the crankshaft from turning, tighten the pulley mounting bolt to the required torque.
Put on a toothed belt and adjust its tension.
