DISASSEMBLY/REASSEMBLY
Do not demount when hot or the part could become
deformed.
Cylinder head
If the surface of the cylinder head is deformed, flatten it by removing
0.2 mm of material at most.
Always replace the seal. See figs 46-47-48-49-50 when selecting
the thickness. The bolts must be tightened in different phases for the
various engines, in compliance with the order shown in the figure:
First tighten the 4 screws M10, then the 2 side screws M6.
Lubricate the shanks of the bolts, under their heads and the
washers with engine oil. Do not use too much oil. Oil that deposits in
the threaded hole on the cylinder block could become pressurized
during the tightening phase, sensibly diminishing the driving force.
Always make sure that the holes on the cylinder block are dry and
clean.
Injector projection
The end of nozzle A should project 2,5 mm for 15 LD 225-315-350
and 3,0÷3,5 mm for 15 LD 400-440 from the cylinder head plane.
Adjust with copper gaskets B with thickness of 0.5, 1 and 1.5 mm
