Bevel-drive Adjustment
Bevel-drive Adjustment Currently used bevel drive operates under severe conditions, but extends satisfactory service provided correct adjustment of the gear is made. Every manufacturer provides detailed specifications of special tools to be used, clearances to be maintained, etc. It is necessary to strictly follow this information before attempting such an overhaul. The final drive produces noise due to the bearing defects or incorrect meshing, which may be caused by bearing wear. Usually noise or 'whine' on the drive is produced due to the gear with too deep in mesh, and noise on the over-run is caused by insufficient depth of mesh. The cause for a final-drive noise should be determined soon whenever it develops. Misaligned gears 'mate' to the new position, so it becomes impossible to obtain a quiet operation even when the adjustment is corrected. A delay in repair may require the installation of a new crown wheel and pinion as well as bearing.
