Rocker arm pivot, dismounting and remounting
To remove pivot 1 from the support 2 it's necessary to drill out pin 3
using a 4mm drill bit.
On remounting insert a new pin and reinsert it in bearing surface A
(0 to 1 mm).
Check the rod’s state of wear and tear (diam. B) and that of the
rocker arm holes (diam. C).
Remove the closing caps 4 at the end and carefully clean inside.
Dimensions (mm):
Camshaft, disassembly
Loosen the screws and remove the cover 1.
Check gasket ring 2 for integrity.
Remove the drive rod from the fuel pump.
Gently remove the camshaft, slight rotations may be required to
avoid binding the camshaft lobes against the camshaft bearing
surface bores.
Note: The lift pump drive eccentric 3 is included on the flywheel end
of the camshaft and fixed with a screw.
In case of replacement tighten the eccentric screw at a torque of 80
Nm.
Camshaft, journal and housing measurement
Use an inside micrometer gauge for housing diameters and an outside
micrometer gauge for journal diameters.
