Disconnect the height control tube.
for Except Front Pneumatic Cylinder:
Pinch "A" to disconnect the No. 1 connector and pull it out from the housing.
*1 | Height Control Tube |
for Front Pneumatic Cylinder:
Pinch "B" to disconnect the holder air connector clip and pull it out from the No. 1 connector. Pinch "C" to disconnect the No. 1 connector and pull it out from the housing.
*1 | Height Control Tube |
Set SST to the tube.
*1 | Plate |
*2 | No. 2 Connector |
*3 | O-ring |
*4 | Height Control Tube |
Insert SST into the housing to expand the claw of the plug or tube connector in the housing.
Pull out the tube with SST inserted.
Note
Do not force the tube.
Insert a screwdriver into the circular hole on the housing, and remove the No. 2 connector, 2 O-rings and plate from the housing.
Tech Tips
The O-rings, plate and No. 2 connector are non-reusable parts.
*1 | O-ring |
*2 | Plate |
Install 2 new O-rings and a new plate.
Note
When replacing the parts onto which the tube is to be installed with new ones, it is not necessary to perform this installation procedure.
Apply MP grease to 2 new O-rings and a new plate, and then install them to a straight tube.
Note
Install the plate between the O-rings.
Air leaks may occur if dust or foreign objects come into contact with the O-rings.
*1 | O-ring |
*2 | Plate |
*3 | Cardboard |
Insert the tube onto which the 2 O-rings and plate are installed into the housing, and then lightly push them in with a piece of rolled up cardboard or equivalent.
*1 | No. 2 Connector |
Push a new No. 2 connector into the housing until a clicking sound is heard.
*1 | Housing |
*2 | Claw |
*3 | No. 1 Connector |
*4 | Port (Hole) |
*5 | Height Control Tube |
Install the height control tube.
Push the height control tube to the housing until a clicking sound is heard.
Push the No. 1 connector to the housing until a clicking sound is heard.
Note
Turn the claw of the connector 90° so that the claw is aligned with the housing port as shown in the illustration.
Lightly pull on the tube to make sure that it is securely connected.
*1 | No. 1 Connector |
*2 | Air Connector Clip Holder |
for Front Pneumatic Cylinder:
Push the air connector clip holder to the No. 1 connector until a clicking sound is heard.
AIR CHARGING
Note
Do not use factory air.
In order to prevent the battery from becoming fully depleted, connect the battery charger to the auxiliary battery when turning the power switch on (IG) to charge the battery.
Keep the power supply connected to prevent the GTS battery from becoming fully depleted.
The pressure will change according to the temperature.
