The purpose of this document is to provide Boeing Customers of PW2000 Series engine equipped 757 airplanes with basic information to assist them in planning and design of engine ground handling equipment. Included in the data are weights, centers of gravity (CG), hard point locations, engine mount locations, ground clearances and ground handling load limitations.
Drawings of ground handling equipment required for the engine and its components are provided to each 757 customer along with a description of each. In addition, all Boeing-designed ground support equipment (GSE) is identified and illustrated in the Boeing 757 Illustrated Tool and Equipment Manual.
Information regarding bare engine GSE requirements is the responsibility of the engine manufacturer: Pratt & Whitney Aircraft Attention: Powerplant Maintenance Engineering Support Services Commercial Products Division 400 Main Street East Hartford, CT 06108 Occasionally, specifications change in the course of engine development. New information will be obtained
and incorporated in the document during the revision cycle. Hence, dimensions, weights and drawings shown in this document are to be used for planning purposes only. Verification of such data as engine weights and dimensions may be obtained from the latest P&WA drawings. Engine installation weights shown are approximate. Actual weights will depend on the airplane engine configuration.

1.2 DESCRIPTION
1.2.1 Description
The PW2000 series engine was developed by P&WA for the 757 airplane. It is a two spool, high bypass ratio, new generation turbofan engine producing approximately between approximently 37,000, lbf and 42,600 lbf (189,494 N) (depending on the configuration) of uninstalled takeoff thrust flat rated to 968F (368C) at sea level, static conditions. It has a single stage fan and a four stage low pressure compressor driven by a five stage low pressure turbine.
The PW2037, PW2040 and PW2043 are nearly identical except for differences in uninstalled takeoff thrust.
The core engine consists of a twelve stage high pressure compressor with variable stator vanes in the first five stages, an annular combustor, and a two-stage high pressure turbine. Active clearance control is utilized above an altitude of 15,000 ft (4572 m) to improve the efficiencies of the high and low pressure turbines by controlling running clearances.
