Drive timing
1 - an asterisk of a camshaft; 2 - rotor pulses to the Hall sensor; 3 - the bolt of the camshaft sprocket 10 Nm. Before screwing the bolt lubricate the bottom surface of the bolt head with a thin layer of engine oil. When tightening the bolt Grip camshaft with a wrench 24; 4 - turning finger 18 Nm; 5 - a sealing ring. If damaged, use a new sealing ring; 6 - chain tensioner, 40 Nm; 7 - shoe; 8 - an asterisk; 9 - duplex roller chain. Before removing the chain direction of rotation check circuit; 10 - a bolt, 100 Nm; 11 - an asterisk; 12 - a bolt, 10 Nm; | 13 - chain tensioner. Before you remove the chain tensioner with a screwdriver loosen the locking toothing and separate the chain guide of the tensioning device. To turn the engine can only be established by the chain tensioner; 14 - sprocket chain 15 - single chain; 16 - chain guide; 17 - Special finger to guide the chain 10 Nm; 18 - a directing finger flange 10 Nm; 19 - a bolt, which is mounted with a special tool VW-D6, 20 Nm 20 - a bolt, 20 Nm; 21 - chain guide; 22 - a bolt, mounted with a special tool VW6, 20 Nm; 23 - guide ring; 24 - an intermediate shaft | Places tagging before removing the timing chain drive

| 1 - chain: 2 - chain guide; 3 - chainrings intermediate shaft; 4 - an intermediate shaft sprocket;
A - lock mechanism chain tension; B - Installation tooth on crankshaft sprocket must be aligned with the connector main bearing cap number 1; C - adjusting label on an asterisk of an intermediate shaft; D - marks on the intermediate shaft sprocket |
Timing is performed by the crankshaft, not directly, but through an intermediate sprocket. On the same shaft with the intermediate sprocket fixed sprocket of smaller diameter and through which a second chain is driven timing mechanism. The upper camshaft drive chain is tensioned via tensioning device plate, which is held in position by means situated outside the adjustment bolt. Lower timing chain drive has a hydraulic tensioner that requires no adjustment.
PERFORMANCE ORDER | 1. Before removing the timing chain drive, using paint, apply a label on the circuit in the areas shown in Fig. Places tagging before removing the timing chain drive. | | 2. Turn the crankshaft in a position in which the piston of the first cylinder is established in the top dead center. This marks on the pulley / damper crankshaft must be aligned with the pointer on the housing chain. | 3. Installation of the piston of the first cylinder at TDC on the intermediate shaft sprockets should be visible groove (see. Fig. Location sprocket groove on the intermediate shaft at installation of the piston of the first cylinder to TDC in the compression stroke). If the sprocket groove of the intermediate shaft is not visible, rotate the crankshaft one complete revolution and repeatedly combine adjusting labels with indexes. | | 4. Fix the camshaft by inserting special tool VW-3268 in the camshaft grooves. | | 5. When unscrewing bolts camshaft sprocket using wrench flats for holding the camshaft from turning. |
