②

Separate ﬁtting boss (0) in the following manner:

(a) Remove C-shaped stop ring (20), O-ring retainer (208) and O-ring (20). (b) Taking off four hex

socket head setscrews (0B), remove ﬁtting boss (0).

③

Sensor Removal

Taking off four hex socket head bolts (08) in this state, the sensor (20) can now be separated.

Do not force but pull it carefully until out.

(3) Sensor Installation

Reverse the order of steps (2) above, observing the following instructions:

CAUTION

①

When installing the sensor, make sure that the O-ring (204) is in place. If this O-ring is

distorted or otherwise damaged, replace with a new one.

②

Align the locating pin of sensor (201) with the pin slot of shaft assembly (102) and bluff

body (105). You cannot disassemble sensor (201).

CAUTION

Sensor (201) cannot be disassembled. If found to be defective, it should be replaced as an

assembly.
