2. Checking the clearances
Clearance Clearances between guide shoes and guide ways:
The corresponding crankpin must stand in such a position
that guide shoes 2 lie on guide ways 4 on fuel or exhaust
side.
Clearance
is valid for the whole guide way length and is
measured according to the positions as shown in Fig. ’B’.
Clearance Lateral clearance of crosshead between the columns:
The clearance is measured in every position of the cross-
head. The complete crosshead must be pressed axially to
a side with suitable hardwood wedges or similar aids. The
pressure must be exerted onto the guide shoe or the
middle part 7 and not onto the crosshead pin 1.
Clearance Lateral clearance between middle part and
crosshead pin:
Push the corresponding middle part to the stop of the re-
taining cover 10 in the above mentioned position of the
crosshead.
Clearance Radial clearance between crosshead pin and
middle part:
This clearance is very difficult to establish inside the en-
gine. It is therefore best to measure and calculate this
clearance on the removed crosshead. For this the pin di-
ameter and the bore in the middle part have to be mea-
sured with micrometers.
