MAINTENANCE

Series 855 pumps are designed for long, trouble-free service life under a wide variety of application conditions with a minimum of maintenance. The points listed below will help provide long service life.

CLEANING PUMP:

Keep the pump as clean as possible. This will facilitate inspection, adjustment and repair work.

LUBRICATION:

Some bearing carriers require external lubrication. This must be applied slowly with a handgun to lubrication fittings every 500 hours of operation with multi-purpose grease, NLGI # 2. Do not over-grease. Applications involving very high or low temperatures will require other types of lubrication. Refer to ESB-515. Consult factory with specific lubrication questions.

STORAGE:

If the pump and coupling are to be stored, drain the pump and pour non-detergent SAE 30-weight oil into the pump port. Apply grease to the pump or the coupling shaft extension, if present or accessible.

Viking suggests rotating the pump shaft every 30 days to circulate the oil in the pump. The coupling should be stored in a dry area.

Note: If the liquid to be pumped reacts with oil, use an acceptable alternate.

SUGGESTED REPAIR TOOLS:

The following tools are required to properly repair Series 855 pumps. These tools are in addition to standard mechanics’ tools such as open-end wrenches, pliers, screwdrivers, etc. Most of the items can be obtained from an industrial supply house.

1.Soft face hammer

2.Metric Allen wrenches (for set screws)

3.Torque Wrench with a locknut socket
