Inspection / Gauging
Check (TDC) piston reversing mark. If it exceeds
some 0,2 mm, gauge liner. Following installation of a
new liner, a check for roundness will be sufficient.
To begin with, carefully clean liner and stadia
and cover up the crankcase interior below the
liner.
Job:
Set micrometer to nominal liner diameter. Suspend
stadia (1) in liner (2). Gauge liner axially and radially at
the stadia levels provided. To do this, hang stad ia in
the respective direction.
The gauging levels are provided by 3 holes in the
stadia. Record all readings. When the specified limit
is exceeded, replace liner.
Nominal bore Ø 240 mm dia.
Wear limit
(measured at TDC
of 1st and 2nd
compression ring) Ø 241 mm dia.
Maximum ovality 0,072 mm
If ovality is exceeded, remove liner and trace
cause (Job Ca rd 03.04.01).
Gauging levels from liner top:
a = 60 - 61 mm
b = 190 mm
c = 340 mm
Renew cylinder liners which have almost rea-
ched the wear limit after more than 50,00
running hours.
Tools:
- Stadia (fabricated locally),
- Block gauge
