- Tightening torque - 29 Nm
Note: Apply engine oil to the threads and under the bolt heads.
2. Install the camshaft by pushing it back and forth in the cylinder head.
3. Install the indicator on the end of the camshaft and reset its readings. By moving the camshaft back and forth, determine the axial clearance.
If the clearance is greater than maximum, replace the camshaft cover and recheck the clearance. If the clearance still exceeds the maximum, replace the camshaft.
Axial clearance of the camshaft:
- nominal - 0.05-0.25 mm
- maximum - 0.50 mm
4. Clean the camshaft. Replace the camshaft if any of the cams are chipped or heavily worn.
5. Measure the diameter of each camshaft journal.
6. Zero the indicator on the neck diameter reading.
7. Clean the surface of the bearing shells in the cylinder head. Measure the inside diameter of each bushing and check for out-of-roundness.
If the clearance between the camshaft and the main shaft bearing is less than the maximum, then go to step 9.
If the clearance exceeds the maximum, with a new camshaft, replace the cylinder head.
- Nominal clearance - 0.045 - 0.084 mm
- Maximum clearance - 0.100 mm
8. Check the runout of the camshaft by placing it in V-shaped prisms.
- Rated runout - 0.03 mm
- Maximum runout - 0.04 mm
9. Check the height of the camshaft lobes.
