Camshaft lobes
Check that they do not show blue colouring, pitting or scratches; otherwise, replace the camshaft and the relevant toothed wheel.
Use a micrometer to check the sizes (a) and (b) of the camshaft lobes.
Camshaft lobes sizes:
- Inlet:
- a: 36.28 / 36.32 mm (1.4283 / 1.4299 in); Limit: 36.15 mm (1.4232 in);
- b: 28 mm (1.1023 in);
- Outlet:
- a: 35.13 / 35.17 mm (1.3831 / 1.3846 in); Limit: 35.00 mm (1.3779 in);
- b: 28 mm (1.1023 in);
Fasten the camshaft in horizontal position, as shown in the figure, and make it spin to check the eccentricity with a dial gauge; if necessary, replace the component.
Camshaft eccentricity maximum limit 0.040 mm (0.0016 in)
