SUMMARY

Purpose –

This report documents the work done under EWR#19888 – To perform DVA for understanding

assembly tolerances from Flywheel housing to engine mounts, fan support & Charge Air Pipe on Keb

Engine, ISB6.7L Config no. D313017BX03 for OEM Scania

Background –

Scania team requested to perform DVAs between flywheel housing datum A, B & C and Fan support,

Charge air pipe & left and right engine mounts in all 3 directions for understanding assembly tolerances

for engine positioning in Vehicle.

Conclusion –

Detailed analysis results are shared with Scania team and received their confirmation.
