Loosen the two bolts securing the toothed belt tensioner and use a screwdriver to move the tensioner away from the belt, compressing the spring. Remove the toothed belt from the camshaft pulley. Remove the toothed belt from the camshaft pulley, holding the pulley from turning with a rod or screwdriver. When installing the pulley in place, you must use a new bolt. Check the condition of the pulley Install the key and pulley on the camshaft and secure with a new bolt. The thread of the bolt must be lubricated with a special blocking compound (see fig. 2B.17. 2B.18).






Check the alignment of the marks on the pulleys. which should not change, and install the belt on the camshaft pulley. Adjust the toothed belt tension.

Install the timing belt top cover

Crankshaft pulley. Remove the toothed belt.

Remove the crankshaft pulley. If the pulley is too tight, use a puller to remove the pulley. Remove the axle race and key from the crankshaft.

Check the condition of the pulley. Install the axle ring with the curved side facing the O-ring. Lubricate the O-ring and crankshaft pulley with engine oil, then install the pulley on the crankshaft.

Using the auxiliary drive belt pulley and mounting bolt, install the toothed pulley to the crankshaft. Remove the auxiliary drive belt pulley. Install the toothed belt.
