(Note, Do not lubricate the static side (outer portion) of the seal. This could cause the seal to rotate in the bore and leak.) 6 Carefully slide the seal over the motor shaft and press it firmly until is fully seated against the spacer and the seal cannot be pushed any further. 7 Run your finger around the perimeter of the seal to insure it is flush against the back of the barrel. 8 Reinstall the blade assembly. Rotate the assembly while inserting it to insure that it is fully seated on the motor shaft. (Figure 30) 9 Lubricate the faceplate o-ring. 10 Re-install the faceplate and replace the four (4) mounting nuts. Hand tighten the nuts until the faceplate makes contact with the gasket, then use a wrench to tighten the nuts an additional 1/4 turn. Be careful not to overtighten the nuts or cracking of the faceplate may result. 11 Clean the drip tray and tube using warm water. 12 Perform the seal leak test in .

Side View of Seal and Spacer on Motor Shaft MOTOR SEAL LEAK TEST After replacing the motor seal, it is advisable to test the seal under pressure before refilling the barrel with product. Perform the procedure in to verify that the seal is installed properly and not leaking. When the seal passes the leak test, perform the motor calibration routine on page 38. Table 47. Step Action 1 Turn the 3-way Product Supply valve behind the splash panel (see Figure 26) to the Off (horizontal) position. 2 From the Maintenance menu, press the FILL button for the barrel. This pressurizes the barrel with CO2. 3 Observe the water and syrup fill solenoids. 4 If there are NO seal leaks, these solenoids cycle off within a minute and remain off. 5 If the solenoids cycle off and remain off, the barrel seal is not leaking and the barrel is ready to be filled with product. 6 If the solenoids do not cycle off, or cycle off and on, the seal is leaking and the seal installation process described in and must be repeated. 7 If there are no leaks, turn the 3-way Product Supply valve to the BRIX position.
