5.5. Installation

5.5.1. Inspection prior to installation

Measure the correctness of flywheel and flywheel housing. Prior to inspection, clean the flywheel and
flywheel housing.

1) Measuring flywheel housing

Measure the flywheel housing surface
and install the dial gauge (1/1,000) at the
flywheel so as to be vertical to the
flywheel housing, and let the gauge stem
to contact to the flange. Rotate the
flywheel, and measure the surface error
of flywheel housing flange. The surface
error should not exceed 0.2 mm.

2) Measuring bore of flywheel

Housing Attach the gauge as above so
that the gauge stem may contact the
flywheel housing bore as the right figure.
Measure the eccentrics of flywheel
housing bore by rotating the flywheel.
The eccentrics should not exceed 0.2
mm.
3) Measuring deformation of flywheel
installing surface
Fix the dial gauge to the flywheel
housing so as for the gauge stem to be
vertical to the surface to be installed. The
deviation quantity should not exceed
0.127 mm/inch.
