Removal
The sequence of operations for removing the belt is as follows:
- disconnect the wires from the battery;
- unscrew the nut securing the generator to the tension bar, turn the generator and remove the drive belt.
- set the gear shift lever to neutral position;
- remove the upper protective cover of the camshaft drive;
- turn the crankshaft until the marks on the camshaft pulley align with the mark on the cylinder head cover, and the marks on the crankshaft pulley align with the long mark on the camshaft drive cover (see fig. 73);
- remove the middle and lower protective covers of the camshaft belt drive;
- remove the tension roller bracket spring;
- loosen the bracket mounting bolts, move it to the extreme left position and remove the camshaft drive belt.
Installation
Install the new belt in the following order:
- put the belt on the crankshaft pulley and, pulling the belt counterclockwise, put it on pulley 8 (see fig. 19) auxiliary drive roller and tension roller 4;
- place the belt from the front end onto the camshaft pulley 5, pressing the bracket 6 to the right, and install the spring 7.
Install the middle protective cover of the belt drive without tightening the mounting bolts. Smoothly turn the crankshaft two revolutions, keeping the belt under constant tension and without loosening it when the shaft stops. Check the alignment of the timing marks on the camshaft pulley and the cylinder head cover, as well as on the crankshaft pulley with the long mark on the middle protective cover. If the marks match, tighten the 3 bolts securing the tension roller bracket, first the right bolt, then the left. If the marks do not match, repeat the belt installation operation, adjusting the position of the camshaft pulley.
Install and secure the lower, middle and upper camshaft belt cover. Put on the alternator drive belt and adjust its tension. Connect the wires to the battery, check and adjust the ignition timing if necessary.
