While firmly pressing SST (claw set) into rib of the urea pump gauge retainer, tighten SST (bolt).
| *a | Tighten Start Position |
| *b | Co-rotation Prevention Check Mark |
While one person presses the urea pump into the urea tank sub-assembly, have another person firmly press the urea pump gauge retainer into the threads of the urea tank assembly and tighten approximately one and a half turns.
Note
Do not any tools other than SST, such as a screwdriver, etc.
Do not excessive force when pressing down on SST, as the urea pump will place excessive force on urea pump gauge retainer and be difficult to remove, and parts may be damaged.
Do not use an impact wrench or turn SST handle with excessive force, as parts may be damaged.
Do not rotate the urea pump gauge retainer when the co-rotation prevention check mark is out of place.
| *a | SST (Plate) |
| *b | Person in Change of Tightening |
| *c | Person in Charge of Supporting |
While one person presses the urea pump into the urea tank sub-assembly have another person slowly tighten approximately half turns.
| *a | SST (Plate) |
| *b | SST (Handle) |
| *c | Tightening Complete Position |
| *d | Rotational Start Point Mark of Urea Pump Gauge Retainer |
| *e | Person in Charge of Tightening |
| *f | Person in Charge of Supporting |
|
Tighten |
Install SST (handle) to SST (plate).
While one person presses the urea pump onto the urea tank sub-assembly, have another person use SST (handle) and slowly tighten the urea pump gauge retainer until it reaches the tightening complete position.
INSTALL UREA TANK SUB-ASSEMBLY
Install the clip to the urea tank sub-assembly.
Install the urea tank sub-assembly to the body with the 3 bolts and clip.
CONNECT UREA TUBE WITH HEATER ASSEMBLY
Note
Check for dirt or mud on the urea pump and around the urea tube connector before connection. Clean if necessary.
Connect the urea tube with heater assembly to the urea pump.
Tech Tips
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.
Wash the connection area of the urea tube connector with water to remove all solidified urea solution (white solids).
Wipe off the connection area of the urea pump with water to remove all solidified urea solution (white solids).
Align the axis of the urea tube 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.
