IRREGULAR NOISE CAUSED BY THE DV GEAR
ONE-WAY CLUTCH DAMAGE
1.General: Wear in the 12T DV gear boss contaminates the one-way clutch of the DV gear which
locks and causes to damage the boss of the DV frame 80R. To prevent this, the surface
treatment of the DV frame 80R boss is changed from manganese phosphate to
electroless nickel plating.
2.Phenomenon: Irregular noise generation from within the DV unit.
3.Action: (Factory action)
• The DV frame 80R boss is surface finished with a new method as beginning from
October, 1991.
• The same applies to the color DV unit boss as beginning from October, 1991.
4.Note: (Identification of the new boss from the old boss)
DV gear (12T)
DV frame 80R

The color of the boss changed
from black to siver.
With this change in the suface treatment, a new parts code is issued for the DV unit.
