Urea Pump Installation

Install a new gasket to the urea tank sub-assembly.

Install the urea pump to the urea tank sub-assembly as shown in the illustration.

Put the urea pump gauge retainer to the urea tank sub-assembly. While holding the urea pump, tighten the urea pump gauge retainer one complete turn by hand.

Set SST on the urea pump gauge retainer.

SST

09808-14030(09808-01030,09808-01040)

HINT:

1. Engage the claws of SST securely with the urea pump gauge retainer holes to secure SST.
   
2. Install SST while pressing the claws of SST against the urea pump gauge retainer (towards the center of SST).
   

Using SST, tighten the urea pump gauge retainer is within range A on the urea tank sub-assembly as shown in the illustration.

NOTICE:

Remove any foreign matter around the urea pump before this operation.

HINT:

Fit the tips of SST onto the ribs of the urea pump gauge retainer.

Install the urea tube with heater assembly to the urea pump.

HINT:

If there is any solidified urea solution (white solids) on the connection areas of the urea tube with heater assembly and urea pump, clean the solids off with water. Otherwise, they may prevent the O-ring from sealing properly.

1. Wash the connection area of the urea tube connector with water to remove all solidified urea solution (white solids).
   

2. Wipe off the connection area of the urea pump with water to remove all solidified urea solution (white solids).
   





3. Align the axis of the connector with the axis of the urea pump. Push the urea tube connector into the urea pump until the urea tube connector makes a "click" sound.

4. After connecting the urea pump and the urea tube connector, check that the urea pump and urea tube connector are securely connected by trying to pull them apart.
   

5. Attach the lock claws to the urea tube connector by pushing down on the cover.
   

Connect the urea tube with heater assembly to the hose clamp.
