2. Check the operation of the plunger and tensioner lock. The plunger should move freely in the housing bore (left). The lock should hold the plunger securely (right).
3. Check the cleanliness of the oil injector jet.
Installation
Designation of chain cover mounting bolts of different sizes
Bolt A - 30 mm
Bolt B – 50 mm
Bolt C – 60 mm
1. Clean the front of the engine, chain and cover, install new O-rings and nozzle. The nozzle should be facing the chain.
2. Place the chain on the camshaft sprocket, aligning the marks, crimp the chain with the dampers, tying it with strong tape.
3. Align the other link with the distinctive mark with the groove for the crankshaft key (arrows) and put it on the drive sprocket.
4. Apply a 3mm bead of sealant to the cap, ensure all gaskets are in place and install the cap (within no more than 5 minutes after application), by engaging the shaft of the leading rotor of the oil pump with the leading gear of the crankshaft.
5. Tighten the bolts (see fig. Designation of chain cover mounting bolts of different sizes) and tighten to the specified torque. Remove the chain tie.
6. Install the remaining parts in reverse order. Start the engine only after checking that the chain is installed correctly.
