S e r i e s 37-90
W h e n the front propeller shaft and housing is
removed from the V - 1 6 transmission, a cork should
immediately be placed in the oil hole in the rear
of the transmission to prevent loss of transmission
lubricant as explained in N o t e 10. B e sure that
this cork is removed when replacing the front
propeller shaft and housing as failure to do this
will prevent lubrication of the speedometer gears
and the front propeller shaft bearing.
