Comment. Work can be done without this device if you can unscrew the bolts securing the camshaft pulleys.
Execution sequence
1. Remove the upper front timing belt cover (see «Timing Belt - Checking Condition»).
2. Using a 17 mm socket wrench, turn the crankshaft until the marks on the camshaft pulleys match the marks on the rear cover of the timing belt (see «Timing belt - replacement»).
3. Alternately holding the camshaft pulleys with a special tool, loosen the pulley mounting bolts with a 17 mm wrench.
Recommendation. If there is no tool to hold the camshaft pulleys, they can be locked using wooden wedges.
4. Loosen the tension of the timing belt (see «Timing belt - replacement»).
Inlet valve shaft marked 1006015.
In addition, the intake valve shaft has an additional belt.
Attention! When repairing the engine, do not use a sealant with a high content of silicone (silicon compounds), whose vapors can get through the crankcase ventilation system into the cylinders and further into the exhaust tract. Use a sealant specifically labeled as safe for the oxygen sensor.
Attention! Do not apply too much sealant to the mating surfaces of the bearing housing. When tightening the mounting bolts, the sealant squeezed into the internal cavities of the engine can clog the oil channels.
3. We also apply a thin layer of Loktite-574 sealant to the lower surface of the bearing housing around the holes of the candle wells, as well as...
... and on the plane of the cylinder head according to the following scheme:
4. We install the camshafts in the cylinder head with the keyways up.
5. We install the bearing housing on the cylinder head and evenly tighten the bolts of its fastening until the bearing housing contacts the cylinder head. We finally tighten the bearing housing mounting bolts in pairs, with a torque of 8.0-10.0 Nm (0.8—1.0 kgcm) in the sequence shown in the photo (see below).
The sequence of tightening the bolts of the bearing housings
6. With a rag, remove excess sealant squeezed out of the gap between the cylinder head and the bearing housing cover.
7. We press in the camshaft seals (see «Camshaft seals - replacement»).
8. We press two plugs into the cylinder head.
9. Further assembly is carried out in the reverse order of disassembly.
