* In case of repair using this parts, replace the parts according to the following instruction.

Replacement Procedure I[For replacement of old models (e.g. PD116) to PS8040A or PS8050A]

1. Dismount the pressure sensor. (Since the existing relay harness to the

PCB is reused, do not dismount it.)

2. Use the existing holes to mount the existing mounting plate (accessory d ).

3. Use the resin band (accessory a ) to fix the pressure sensor.

(Securely fix the band in the nut position.)

To mount the capillary ass’y (1) to the pressure sensor, torque it to 15.7N·m±10%.

4. Reinstall the wirings and the capillary of the pressure sensor.

Form a single loop in the capillary after coming out from the switch box.

5. Use the post with the XH base (accessory b ) to connect the harness from the existing PCB and that from the substitute pressure sensor.

Connect the harnesses to the connector, and then wind the vinyl tape around the connector.

Tie excess lead wires using the cable ties.

* The connector may be difference from the original one in the color. However, that will present no problem.

Replacement Procedure II[For replacement of PS8030A to PS8040A or PS8050A]

1. Dismount the pressure sensor from both the capillary and the connector.

2 Make holes in proximity to the previous sensor mounting position as shown in figure on the left. And then, mount the mounting plate (accessory d ).


(Securely fix the band in the nut position.) To mount the capillary ass’y (1) to the pressure

sensor, torque it to 15.7N·m±10%.

Replacement Procedure III[For replacement of old model SP8601 (2 output products) to PS8040A or PS8050A]

1. Dismount the pressure sensor from the both capillary and connector.



(Securely fix the band in the nut position.) To mount the capillary ass’y (2)

to the pressure sensor, torque it to 15.7N·m±10%.



5. Connect the harness from the substitute pressure sensor to the wire harness (accessory c ), and further to the wire harness (accessory m ) using the post with the XH base (accessory b ).


Tie excess lead wires using the cable ties.* The connector may be difference from the

original one in the color. However, that will present no problem.

Replacement procedure VI

Since the part concerned has perfect compatibility, replace it without modification.

1. However, follow the fastening procedure below to prevent the threads from being broken due to excessive fastening.

a. Mount the pressure sensor by fastening it by hand.[For Toyoda Machine Works, Ltd. make, make sure that a spacer (e.g. brass C ring) is inserted in the nut.]

b. Fasten the pressure sensor in the range of 30 to 60° from the position to which it is fastened by hand.

c. Check for airtightness.

2. To mount the harness to the pressure sensor, follow the procedure shown below to prevent rainwater from entering the switch box (for the substitute parts PS8050A and PS8051A).

To prevent the harness from coming in contact with other piping or else, form an upward half loop in the base of the protection tube.

Pressure sensor

Connect the harness with the protection tube end facing downward.

Fix the harness with cable ties provided.
