The following are procedures for servicing the major components of the Viper 
system.

The barrel motor seal is typically replaced during the semi-annual preventative 
maintenance procedure. The seal location is shown in Figure 40.

To remove the existing barrel seal, perform the procedure in Table 42.

1.

Purge the barrel. See “Purging a Barrel” on page 28.

2

When purging is complete, disconnect power from the unit.

3

Open the relief valve on the front of the barrel to ensure that pressure is 

released. 

CAUTION: Barrel pressure MUST be relieved before removing the 

faceplate!

4

Remove the four (4) 3/4 in. nuts from the faceplate and slowly remove the 

faceplate from the unit.

5

Carefully pull the blade assembly out of the barrel.

6

Remove any remaining product from the barrel.

7

Rinse and inspect the blade assembly and barrel for signs of wear. (Replace if 

necessary)

8

Remove the seal and spacer from the rear of barrel.

When old seal and spacer are removed, use a clean soft cloth to clean 

between the motor shaft and the barrel to remove any remaining product.
