Abstract: A pump sleeve for an inversion pump in an integrated drive generator has a pump sleeve body extending between a first end and a second end, the first end being at a location adjacent an enlarged endplate. The body extends to the second end with a generally cylindrical body portion having a bore of an inner diameter from the first end to the second end, and between the first and second ends for a distance. A ratio of the first distance to the inner diameter being is 1.8 and 2.0. In addition, an integrated drive generator is disclosed as is a method of replacing an accessory drive gear in an integrated drive generator.

Abstract: A variable wobbler plate has a stub shaft and a pivot shaft. The pivot shaft has a smaller diameter portion and a larger diameter portion. The smaller diameter portion has a generally cylindrical outer periphery with a flat over a limited circumferential extent and a diameter to opposed portions of the generally cylindrical portion defining a first distance. A second distance is defined from an end of the smaller diameter portion spaced furthest from the stub shaft to an end of the larger diameter portion spaced closest to the stub shaft and measured along a central axis of the pivot shaft and defines a second distance. A ratio of the first distance to the second distance is between 0.60 and 0.75. An integrated drive generator and a method are also disclosed.

Abstract: A port plate for use in an integrated drive generator has a body defining a semi-cylindrical charge port communicating with two circumferentially smaller charge port portions. A diametrically opposed working pressure port has three smaller working pressure ports. A center plane is defined extending through a center axis of a bore within the body and equidistance between circumferential ends of the charge port and the working fluid port. A first angle is defined between the plane and a circumferential end of the smaller charge port. The first angle is between 15 and 25 degrees. An integrated drive generator and a method are also disclosed.
