Measuring of K-value of T\C

• K- From bearing flange face to end face of shaft.
• K1- for measuring K1 , slacken compressor side bearing by around 5 to 6 mm and pull it out using extractor tool .Then push the shaft towards compressor side.

• Screw the extractor device on to the inner bearing bush of the compressor end and pull out the bearing about 5 to 6 mm
• Push the rotor towards the compressor side measure K1.
• Same way for measuring K2  , pull the rotor towards turbine side measure the dimension K2

L=K-K1              M=K2-K

• In manual required valus of K ,L and M will be given .
• Basically we are measuring the end play  ie, distance between turbine wheel and casing on either side.
• K value will give an indication of thrust bearing weardown
