Planned maintenance

1. Remove the air inlet pipe, release the cables secured by the retaining bands, then undo the nuts fixing the brake servo vacuum pump to the cylinder head and remove it.
2. Position tool 1860932000 for timing the camshaft, matching the camshaft splining (1) with the projection (2) on the tool. Fix the tool to the cylinder head positioning the centering dowel (3) as illustrated in the diagram. The dowel should be perfectly centered on the tool; if it is not, use a spanner (4) to make extremely small movements to centre the dowel on the tool.
3. Remove the part shown in the diagram, to allow the subsequent positioning of tool 1860933000 to determine T.D.C.. Only fit the timing drive belt on the crankshaft drive gear.
4. Position tool 1860933000 for accurately determining T.D.c. for cylinder n° 1. The tool should be perfectly fixed to the crankshaft drive gear using two bolts and to the crankshaft front cover through another bolt (by the bolt removed previously).
   Then loosen the camshaft drive pulley fixing bolt using tools 1860831000 and 1860848000.
