This section contains troubleshooting to locate and correct the cause(s)

of low pressure compressor rubbing or binding when turned by hand. The

low pressure compressor is mechanically coupled to the low pressure

turbine rotor in the rear engine subassembly. If there is damage to the

low pressure compressor or position No. 1 or 2 bearings in the forward

engine module, or to the low pressure turbine rotor or position No 5

bearing in the rear engine subassembly, binding will be felt when the

low pressure compressor is turned by hand. The art on this page provides

an overview of the low pressure compressor and low pressure turbine

rotor system. Refer to this page along with in-text art while performing

troubleshooting.
