Removal and installation the camshaft of the EW10J4 engine (Peugeot 206)

When removing and installing the gearbox at Peugeot service centers, the following special tool is used:

• calibrated pins for fixing camshafts - 0189-A;
• camshaft seal installation tool;
• tube with tip for valve - SHRADER 0141-T1.

Remove the camshafts in the following order:

• remove the engine protective cover;

• remove pulleys 2 and 3 (figure 3.81) camshafts;
• remove compact coil block 4 ignition;
• remove sensor 6;
• unscrew the bolts securing the cylinder head covers 1 and 5 (unfold one by one in a spiral, starting from the outside);

• lock camshafts 1 and 6 with a 24 mm wrench (figure 3.82), setting the key to the flats 5;
• loosen the tightening torque of the bolts on both camshafts;
• remove hubs 3;
• remove crankcase 2;
• gradually unscrew the mounting bolts of the camshaft journal housing in a spiral from the middle to create a gap of several millimeters between the mating surfaces;
• completely unscrew the mounting bolts of the bed frame and remove it;
• remove the camshafts by applying leverage to each camshaft from the flywheel side to separate the timing side pilot bearing;
• remove the valve lifters, marking them first so that they can be installed in their original position during assembly;
• remove oil from the threaded holes for fastening the camshaft journal housing.

Install the camshafts in the following order:

• lubricate the valve lifters with engine oil;
• install the pushers without mixing them up;
• make sure the tappets in the cylinder head rotate freely;
• lubricate the surfaces of the crankcase under the camshaft bearings with engine oil;

• check for the presence of dowel pins 1 (figure 3.83);
• correctly install both camshafts in the cylinder head;
• apply a bead of SILICONE CATEGORIE 2 sealant around the entire perimeter of the mating surface of the gaskets, as well as into the threaded holes for the mounting bolts;
• install the camshaft journal housing, which has a hole for the sensor 6 (see figure 3.81) from the exhaust system;
• install the housing of the journal beds of the second camshaft;

• pre-tighten the mounting bolts of both crankcases to a torque of 5 Nm in the order shown in Figure 3.84;
• finally tighten the mounting bolts to a torque of 10 Nm in the same sequence;
• install the protective crankcase of the timing mechanism;
• before installing the camshaft seals, make sure there is no sealant residue in the seat;
• install new seals using the tool;
• tighten the hub mounting bolts 3 (see figure 3.82) on the camshafts with a torque of 75 Nm, holding the shafts from turning with a wrench;
• install covers 1 and 5 (see figure 3.81) cylinder heads in a set with sealing gaskets;

• tighten the cover mounting bolts in the sequence shown in Figure 3.85, at the first stage with a torque of 5 N·m and at the second stage with a torque of 11 N·m;
• complete the installation in the reverse order of removal;
• conduct computer programming.
