1. Gasket; 2. Pusher; 3. Oil nozzle; 4. Camshaft; 5. Drive gear; 6. Lid; 7. Seal; 8. Pulley; 9. Power steering pump pulley; 10. Driven gear; 11. Thrust washer; 12. Belt; 13. Fan; 14. Fan clutch; 15. Coolant pump pulley; 16. Side cover
Removal
1. Disconnect the battery from ground.
2. Set the piston of the 6th cylinder to TDC of the compression stroke, for which first set the piston of the 1st cylinder to TDC, and then turn the crankshaft by 1 revolution.
3. Remove the radiator (see subsection 4.5).
4. Remove the air conditioning compressor (if provided) and move it to the side without disconnecting the lines.
5. Remove the fuel pump (on carburetor engines).
6. Remove the distributor. Keep in mind that the runner should be directed towards the 6th cylinder outlet. Before removing, mark the runner position with marks.
7. Remove the cylinder head cover.
8. Remove the rocker arms with shafts and push rods.
9. Remove the pushers.
10. Remove the front cover.
11. Check the clearance in the engagement of the camshaft drive gears. If the clearance is not within the norm, replace both gears.
12. Remove the thrust washer and carefully remove the camshaft, holding it against the block.
13. Check the camshaft end clearance. If the clearance exceeds the norm, replace the thrust washer.
14. Press the gear off the camshaft, removing the retaining ring (1 - up) (if there is no press, then contact a car service).
15. Remove the crankshaft key.
16. Remove the drive gear using a puller.
Installation
1. Clean the parts and check the condition of the gear teeth. If there are chips, flaking, or deformations, replace the gears (change only in pairs). Check the condition of the cylinder block and crankshaft nose (the presence of burrs or scratches that prevent the gear from being removed).

2. Press the drive gear onto the crankshaft with the mandrel, orienting the marking (1) outward and aligning the groove in the gear with the keyway (photo on the left). The recess (2) for the key must be facing upwards (photo on the right).
3. Lubricate the camshaft journals and lobes with molybdenum grease and carefully install the camshaft.
4. Engage the driven gear with the driving gear, aligning the marks (1).
5. Install the thrust washer bolts and tighten to the specified torque.
6. Install the crankshaft key.
7. Install the oil nozzle so that the hole (1) is directed towards the gears. Check the nozzle for cleanliness beforehand.
8. Then the assembly is performed in the reverse order. Keep in mind that the tappets and camshaft are changed only together. Install the remaining parts, fill and start the engine, listen to the operation and make sure there are no leaks.
