1 – bolt, 80–100 Nm; 2 – washer; 3 – mounting pin; 4 – camshaft.
Removal
1. Disconnect the crankcase ventilation hose.
2. Remove the water pump pulley and crankshaft pulley.
3. Remove the timing belt cover.
4. Move the timing belt tensioner pulley toward the water pump and temporarily secure it in this position.
5. Remove the timing belt from the camshaft pulley.
6. Remove the camshaft pulley.
7. Remove the camshaft pulley.
8. Remove the cylinder head cover.
9. Remove the rocker arm shaft assembly.
10. Remove the camshaft bearing caps.
11. Remove the camshaft.
Examination
1. Check the camshaft for uneven wear, cracks or damage.
2. Measure the height of each camshaft lobe at two points.
- Nominal height of intake camshaft cams: 42.8575 mm
- Nominal height of exhaust camshaft: 42.7354 mm
- Minimum permissible height of intake camshaft cams: 42.3575 mm
- Minimum allowable height of exhaust camshaft: 42.2353 mm
3. Check the cam surfaces for uneven wear or damage.
4. Check each bearing for damage. If the bearing running surface is excessively damaged, replace the cylinder head or camshaft bearing cap.
Front camshaft seal ring
1. Check the sealing lips for wear. If the sealing lips are worn or damaged, replace the sealing ring.
2. Check the surface of the camshaft that contacts the sealing ring. If this surface is uniformly worn, replace the camshaft.
Axial clearance of the camshaft: 0.07–0.28 mm.
Installation
1. Before installation, apply a thin layer of clean engine oil to all sliding surfaces of the camshaft. Install the camshaft.
2. Install the camshaft bearing caps.
3. Install the ignition coil.
4. Install the rocker shaft and rocker arms.
5. Lubricate the working edges and the outer surface of the sealing ring with engine oil and use special tool 09221-21000 to install the sealing ring onto the front of the camshaft.
Using a hammer blow on a special device, install the sealing ring until it stops in the socket.
6. Install the camshaft pulley and secure it with the bolt.
Tightening torque: 80–100 Nm
7. Align the camshaft timing mark and the crankshaft pulley timing mark with the pointers, with the piston of the 1st cylinder at TDC in the compression stroke.
