4b. DISMANTLING
1)
Remove the four nuts and conical washers
securing the injector clamps. Carefully withdraw
the injector and copper washers from the cylinder
head. Keep the injectors in a clean place free from
dirt and dust.
NOTE:
Before disassembly of injectors, inspection or
repair of nozzles, contact BOSCH dealer/service.
2)
Using a valve spring compressor, compress the
valve spring sufficiently to allow removal of the
collet (8-5).
3)
Release the pressure then remove the retainer
(2-5) and spring (3-5) the valve seat should also
be removed.
4)
Remove the valve (2-5) and identify them so that
they can be installed in the original positions.
5)
If necessary press out the valve guides from the
under side of the head using pusher slightly
smaller than the guide to prevent it jamming in
the bore.

CLEANING, INSPECTION & REPAIR
(a)
CLEANING
1.
Wash all parts in a suitable solvent and blow
dry with compressed air.
2.
Remove any old gasket material from the
faces of the cylinder head.
3.
Blow through all oil passages to ensure that
they are clear.
4.
Remove all carbon deposits from the cylinder
head and valves.
5.
Remove any carbon deposits from the valve
guides, using a wire brush. Blow out loose
carbon with compressed air.
NOTE:
Guides require careful cleaning because any
remaining carbon will deflect the pilot of a
valve seat refacing tool.
