The coupling shaft installation provides grease fittings for coupling shaft lubrication. The kit adds assurance that the aft spline coupling shaft is continuously lubricated between inspections.
After initial packing of the coupling shaft, the 269GF-100-1 allows the addition of grease by grease gun at 10-hour intervals. This system assures that grease is always available to lubricate the spline couplings. The kit is FAA/STC approved. Weight and balance is not affected.
