19.2 Camshaft drive chain
1. Tensioner; 2. Left pacifier; 3. Right pacifier; 4. Oil deflector; 5. Oil pump drive gear; 6. Leading sprocket; 7. Chain
3. Loosen the bolt and remove the camshaft sprocket (see above).
4. Remove the chain.
5. Remove the oil deflector, oil pump drive gear, and drive sprocket (photo).
19.5 Removing the drive sprocket
6. Check the condition of the sprocket teeth by comparing the tooth profiles on both sides. If hooked teeth are detected, replace the sprocket.
7. The chain is changed together with the worn sprockets, or every 48,000 km. The chain should also be replaced if signs of wear on the rollers are detected.
8. Install the sprocket on the camshaft and check its axial clearance, which should not exceed 0.2 mm.
9. Check the condition of the tensioner and dampers, replace if necessary.
Installation
10. Turn the camshaft so that the valves of the 1st cylinder are closed. Set the crankshaft so that the piston of the 1st cylinder is at TDC.
11. Install dampers.
12. Install the oil deflector, oil pump drive gear, and drive sprocket onto the crankshaft nose. Make sure that the timing marks on the drive sprocket are facing forward (photo).
19.12 When assembling, the key must be facing up and the mark on the sprocket must be facing forward
13. Before installing the chain, turning the crankshaft is not allowed.
14. Place the chain on the camshaft sprocket, then thread it onto the drive sprocket. Tighten the camshaft sprocket bolt. When assembling, keep the following in mind:
- a). The crankshaft key must face upwards.
- b) The chain links with distinctive coloring must be aligned with the marks on the sprockets and located on the right when viewed from the front (photo).
- c). The camshaft alignment pin must fit into the hole in the sprocket number 2 (photo).
19.14a On the Z24i engine, the chain link with the distinctive coloring must be aligned with the mark on the camshaft sprocket, and the camshaft dowel pin must fit into the hole marked number 2
19.14v On the K24 engine, the link with silver coloring must be aligned with the mark on the camshaft sprocket
19.14g On all engines the chain link with the distinctive coloring must be aligned with the mark on the drive sprocket
15. Install the tensioner, adjust the position of the left damper so that there is no gap between the tensioner body and the shoe (photo).
19.15a Move the damper aside.
19.15b There should be no gap between the tensioner body and the shoe after assembly
1. Tensioner; 2. After assembly
16. Install the front cover.
