11.Wipe a heavy layer of anti-seize com- pound onto the threads and mating surfaces of the diffusion hub and retainer.

12.Assemble retainer and diffusion hub with two pin spanner wrenches. Torque to 10 ft-lbs (14 N·m).

13.On systems equipped with abrasive shield, install dust seal gaskets with joints 180° apart.

14.Reinstall vee deflector, orienting apex toward gas flow. Apply anti-seize com- pound to setscrews and tighten with hex wrench.

15.Reinstall probe on stack flange.

16.Turn power on to electronics and monitor thermocouple output. It should stabilize at 29.3 ±0.2 mV. Calibrate probe per Instruction Bulletin applica- ble to your electronics package.

A-13 REPLACEMENT OF CONTACT AND

THERMOCOUPLE ASSEMBLY

Use heat resistant gloves and cloth- ing when removing probe junction box and inner probe assembly. Do not at- tempt to work on these components until they have cooled to room tem- perature. Probe components can be as hot as 800°F (427°C). This can cause severe burns.

Disconnect and lock out power before working on any electrical components. There is voltage up to 115 Vac.

a.Disconnect and lock out power to electron- ics. Using heat resistant gloves and cloth- ing, remove probe junction box cover.

Squeezing tabs on hose clamps, remove hoses from probe junction box, Figure A-19.Remove four screws in corners of probe junction box. Pull probe junction box and in- ner probe assembly free from probe tube. Set on bench and allow to cool to room temperature.

b.Disconnect cell extension wire (orange), thermocouple wire (red alumel), and ther- mocouple wire (yellow chromel) by cutting bomb tail connections from the terminal strip, Figure A-16.

c.Remove two screws, Figure A-19,lock- washers, and flat washers that connect probe junction box to inner probe assembly. Pull heater, V-strut and backplate assembly away from probe junction box. Inspect all O-rings and insulating gasket; replace if worn or damaged.
