2
serial no.
1460 - 275, of a dial indicator
1
serial no. 1460 - 274 inserted in a dial
indicator holder serial no. 1460 - 270.
The function of lever
2
is to reduce the effort required against the re-
sistance of the spring when the valve lowers and comes into contact
with the piston crown near the top dead centre.
The dial indicator tracer
1
rests against the upper spring bearing ring
of the valve.
To sum up, as pressure is placed on lever
2
the valve goes into con-
tact with the piston since the dial indicator
1
is applied to the valve,
allowing to know precisely every movement of the piston from and to-
wards the
TDC
, which is very important for the following operation.
Fuel system
Insert the capillary tester serial no. 1460 - 024 onto the injection pump
union where the high-pressure pipe is usually connected from the
pump to the injector.
To the injection pump connect the high-pressure pump serial no. 1460
- 273 supplied by a tank whose fuel level is at least 100 mm above
the injection pump.
Unscrew the fuel supply union for the injection pump of the cylinder
which is to be worked on.
