This is the parts lists for replacing the old shaft seal and O-Rings in your 750 oil pump. These are available from your local Honda dealer but they will probably have to order these for you. The shaft seal will not show up as a CB750 part but rather as a Gold Wing part. It had the middle number as -300 (91208-300-003) which is an actual CB750 part but has been superceded.
91305-426-003 O-Ring 46 X 2 - seals the oil pump left cover and right cover to the oil pump body. 2 required.
91302-377-000 O-Ring 15 X 2.5 is used with the dowels. 3 required
91302-377-000 O-Ring 15 X 2.5 used on oil leak stopper cap. 1 required
91208-MN1-771 Oil Seal 11 X 15 X 3 used on the drive gear shaft. 1 req'd (superceded part number)
The gasket (15135-300-010) is not available from Honda but CycleX (ENG-002 $9.95) and CB750Supply ($2.00) both list it.
Member Elan also supplies an aftermarket kit that includes the oil leak stopper seal (15166-300-000) and spring (15171-300-010) and possibly? the oil strainer screen (15150-300-000) that is still available from Honda.
