• Remove camshaft sprocket from camshaft.

To install camshaft sprockets

• Place camshaft sprocket on camshaft.
• Install bolt and washer to camshaft. Using Spanner Tool MB990775 hold camshaft sprocket and torque bolt to 95 N·m (70 ft. lbs.) .

TIMING BELT TENSIONER

1. Install timing belt tensioner and tensioner spring.
2. Hook spring upper end to water pump pin and lower end to tensioner bracket with hook out .
3. Turn timing belt tensioner counter-clockwise full travel in adjustment slot and tighten bolt to temporarily hold this position .

INSTALLATION - TIMING BELT

1. Install timing belt on crankshaft sprocket first and while keeping belt tight on tension side install belt on the front (radiator side) camshaft sprocket.
2. Then, install on the water pump pulley and on the rear camshaft sprocket and finally on the timing belt tensioner.
3. Apply rotating force to the front camshaft sprocket in opposite direction to tension the belt tension side, check that all timing marks are lined up
4. Install crankshaft sprocket flange .
5. Loosen tensioner bolt and allow spring to tension timing belt.
6. Turn crankshaft two full turns in clockwise direction. Turn smoothly and in clockwise direction ONLY.
7. Again line up the timing marks on the sprockets and tighten the timing belt tensioner locking bolt to 25 N·m (250 in. lbs.) torque.
8. Reassembly belt covers, engine bracket, insulator, crankshaft pulleys, accessories and accessory drive belts in reverse order.
