9.4.5 Determining the number
of gaskets required
The following gaskets are installed and must
be exchanged:
− Gasket (17)
− Shim (125)
− Seat retainer gasket (126)
Determining height H1
H1 is the height between the facing of the
seat retainer (124) and the facing of the
body (1). See Fig. 9-8.
1. Measure H1 at three places evenly dis -
tributed around the circumference of the
body.
2. Write down the measured values 1 to 3
in Table 9-1. Calculate the average value
and enter it as H1
actual
.
3. Calculate the difference ∆H from the tar-
get dimension H1
target
and actual dimen -
sion H1
actual
and write it down.
