Also a flat bar of the dimensions 10x30 mm can be used.
2 Press or knock
out the ring through the valve guide with
an arbor.
12.3.7 Fitting a new inlet valve seat ring
1 Check the bore diameter
in the cylinder head, see sec-
tion 06.2, pos. 12 in this manual.
2 The ring can be assembled
by freezing in with liquid air
of -190°C, the cylinder head temperature being minimum
20
°
C, or by pressing in with a guided arbor. Always make sure
that the ring contacts the bottom of the bore.
3 Check the excentricity
of the sealing face in relation to
the valve guide, and if it exceeds 0.1 mm the seat surface must
be ground by a seat grinding machine.
12.3.8 Fitting a new exhaust valve seat ring
1 Clean the bore carefully
with a grit 400 or finer emery
cloth.
2 For fitting an exhaust valve seat ring
the tool 834002 is
required.
3 Check the bore diameters
in the cylinder head.
4 Cool the seat ring
in a thermostat controlled freeze box
to -15 - 30
°
C.
Note!
The seal rings will be damaged at lower temperatures.
5 Put the new seal ring
on the seat ring and apply Loctite
272 on the bores in the cylinder head and on the corresponding
surfaces of the seat ring.
6 Put the seat ring
into the guiding bush and press in the
seat with the guided arbor.
7 Check the excentricity
of the sealing face in relation to
the valve guide, if it exceeds 0.1 mm the seat surface must be
ground by a seat grinding machine.
8 Keep the cylinder head temperature
at minimum 20
°
C
for six hours to harden the locking fluid.
9 Pressure test the cylinder head before mounting
with a
test pressure 8 - 10 bar if posssible.
Note!
Mounting of a exhaust valve seat ring should be done carefully
so that the seat ring is correctly seated.
