Figure 9-8: Ceramic Diffuser Element Replacement

A. Threaded probe flange

B. M5-0.8 x 5 mm locking set screw (use 2.5 mm hex key)

C. Spanner wrench

D. Ceramic diffusion element

E. M5-1 x 6 mm setscrew (use 3 mm hex key)
F. Vee deflector

G. Cement fillet
H. Cement port

I. Flame arrestor hub

4. If equipped with the optional ceramic diffusion assembly, remove and discard the

setscrews and remove the vee deflector (

Figure 9-8

). Use spanner wrenches from

the probe disassembly kit (

Table 10-4

) to turn the hub free from the retainer.

Inspect the diffusion element. If damaged, replace the element.

5. Loosen the four socket head cap screws from the cell and flange assembly.
6. Remove the assembly and the corrugated cell.
