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 Dial gauge flywheel so as to be vertical to the flywheel housing, and let the gauge stem Flywheel 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.
Dial gauge EFM6017I 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. Dial gauge Measure the eccentrics of flywheel Flywheel housing bore by rotating the flywheel. The eccentrics should not exceed 0.2 mm. Dial gauge EFM6018I 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 Dial gauge deviation quantity should not exceed Flywheel 0.127 mm/inch. Dial gauge EFM6019I Maintenance of Major Components - 140 -
