Wheelspace Thermocouple Installation

Hi,

I measured low impedance <0.6Mohms on both the 2nd Stage AFT wheelspace TC.

The cables are laid inside the Exhaust plenum "tunnel", sharing the same JB with the exhaust thermocouples. To access the thermocouple, it seems that we have to get through the exhaust plenum where the shaft and couplings are.

1. Is there any best practice or instructions on how to replace the thermocouples? Do we need to remove the exhaust/roof etc.

Thanks,
Fizzeus
