Motor is fitted with a pulley and a torsional vibration damper. As seen in Fig. 76, not all the pulleys have the same design. Mounting holes torsional vibration dampers are in engagement with the pulley by a dowel pin belongs to the corresponding hole pulley. A method of assembling individual components torsional vibration damping system on both engine types are shown in Fig. 90 and 91. On older engines of similar design for the central bolt underlay three elastic washers. Now these abandoned washers, and only one bolt holds the parts on the crankshaft. If the pulley and the torsional vibration damper are made as separate parts, the pulley is bolted to the vibration damper. The scale and pointer are at TDC torsional vibration dampers. To remove and install the components necessary to perform the following operations: - Remove acoustic trim at the bottom of the car, as well as components and spare parts to the front of the vehicle so as to provide easy access to the belt pulley; - Release the tension and remove the V-ribbed belt, as described in the relevant chapter; - To fix the crankshaft from turning. This can include any transfer and apply the parking brake. Otherwise, you can remove the starter and lock properly flywheel (a leading disk - in the case of an automatic transmission); - Remove the crankshaft pulley with vibration damper, if mounted on a hub (see. The left bottom part of Fig. 76). Unscrewing the screws in the inner cavity of the pulley, it is possible to remove parts; - Unscrew the bolt pulley if fitted on the engine parts, shown in the lower left side of Fig. 76 or unscrew the bolt in the center of the torsional vibration damper, if installed on the engine parts, shown in the same figure at the top. If the hub can not be removed using a conventional instrument, use some suitable puller. Each pulley has a predetermined diameter matched to the particular type of engine. Keep this in mind if you need to replace the pulley. When installing the hub and the crankshaft pulley or with torsional vibration damper mounting proceed as follows: - Turn the crankshaft to match the keyways on the crank shaft and the hub, insert the key in the groove and put the shaft hub or a combined pulley / vibration damper; - Put the special washer on the bolt pulley or a combined pulley / vibration damper, heavily greased threaded portion, tighten to 200 Nm, and then finally another 1/4 turn. The crankshaft must be fixed at the same time from turning; - Set the torsional vibration damper and a pulley in the case when the engine is completed, as shown on the lower left side of Fig. 76. Bolts inside the pulley tightening torque 25 Nm; - Install and tighten the V-ribbed belt, as described in the corresponding section; - Perform other work in the reverse order of removal.
