Drive timing

Elements of the valve timing
Fig. 91. Elements of the valve timing: 1 - an intermediate shaft; 2 - leading ring; 3 - bolt 10 Nm; 4 - wheel drive sensor; 5 - bolt 10 Nm; 6 - bolt 25 Nm; 7 - an elastic element tensioning devices; 8 - two-row chain tensioner, 20 Nm; 9 - Double-row chain; 10 - two-lane drive sprocket chain; 11 - single-row chain drive sprocket; 12 - chain tensioner shoe; 13 - sprocket chain drive built into the crankshaft; 14 - Single-row chain; 15 - Strap pacifier; 16 - Special bolt 25 Nm; 17 - finger with collar, 25 Nm; 18 - damper; 19 - bolt 20 Nm; 20 - Stars crankshafts

Timing is carried out not directly but through an intermediate gear shaft 1 (Fig. 91).
Besides on the intermediate shaft is located and a small sprocket 10 which drives a double-row chain 9 timing. On the VR6 engine sprocket 13 at the forward end of the crankshaft driving the single-row chain 14 is a non-removable (rented together with the crankshaft).
Given the tension of two-lane circuit, timing, carried the plate chain tensioner (tensioner) 8 which is controlled by the adjusting bolt inserted outside the chain tension. Single-row chain between the sprocket 13 of the crankshaft and intermediate sprocket 11 also has a tensioning device 12, which is regulated by hydraulic means, and does not require any additional intervention. It should be remembered that the chain tensioner has a blocking device, which must be unlocked before changing the chain tensioner. Double-row chain drive is pressed from the outside inwards by 18 pacifier that prevents hitting the chain drive for the camshafts. Single-row chain also pressed damper 12, but the chain is pressed from the inside out. For fastening bolts and pacifier use special fingers.
