With the running gear in situ, the crank to be measured has to be turned corre-
spondingly after B.D.C. The checking equipment can now be clamped next to the
connecting rod into the provided center punch marks.
⇒ Pretension the dial gauge of checking equipment 94305 and turn the latter
around its own axis for its proper settling.
⇒ Dial gauge must not deviate more than 0.01 mm. Set subsequently dial gauge
to zero.
⇒
Turn crankshaft by means of turning gear, reading the dial gauge in the shown
crank positions at B.D.C. − FUEL SIDE − T.D.C. − EXHAUST SIDE − B.D.C
and noting down the values.
D

procedure it should be again nearly zero. If it deviates more than 0.04 mm
from the first reading, then the measuring must be repeated.
