What steps should be taken when changing lubricant suppliers?

Follow OEM recommendations for each machine
Consolidate lubricants where possible
Test competitive products for compatibility, or flush thoroughly
Analyze new oil to establish a base line

1

What should be the primary source of lubrication recommendations?

The OEM recommendation in conjunction with the lubricating oil supplier.

2

What seven items should be listed on a lubrication survey?

Department (and/or location
Equipment (components and lube points)
Lubricant
Amount
Frequency
Method
Comments

3

Specifications for lubricants should be developed as a cooperative effort between what groups of people in a company that uses lubricants?

Purchasing
Maintenance Engineer
Plant engineer

4

Define “Root Cause” and how it applies to lubrication.

The primary reason for failure in a chain of events. Root cause analysis can prevent further failures by correcting the source rather than the symptoms of an event.

5

Define Failure Mode and how it applies to lubrication.

It is the sequence of events that lead to failure.

6

What are the 12 most common lubrication errors?

Wrong lubrication Water
Quantity Air
Viscosity Particulates
Amount Failure to assign lubrication to one person
Properties To adequately survey
Temperature To keep adequate records
Flow rate To investigate all mechanical malfunctions
Contaminations with another lubricant
To prevent unauthorized personnel from lubricating equipment
To updated and refine lubrication program

7

How might you determine if an oil change interval could be extended?

Oil analysis - viscosity
Total acid number
Spectrographic analysis
Operating history
In engines, look at oil consumption and fuel consumption

8

List five different application intervals that might be listed on a lubrication survey.

Weekly
Monthly
Yearly
As required daily
Every shift

9

What are the components of an oil mist system?

Oil reservoir
air supply
mist generator
heater
manifold
piping
reclassifier

10

What are the major differences between air mist and airline oiler systems.

Misted oil is reclassified, collected, and reused. Airline oilers push oil to the application and is a once through, not reused.

11

What is the generic name for an automatic lubricator?

Trabon

12

Where do you lubricate a roller chain? By what method?

Pin links and roller links. Apply to lower strand before sprocket gear. Brush, oil can, bath, spray, singer, drip, mist.

13

In a high loss system, what can be installed to help monitor oil consumption?

Oil level indicators, pump meter on dispensing equipment, inventory records.

14

What are the disadvantages of oil mist lubrication?

Difficult to set flow rates, environmental concern (stray mist), sensitive to temperature changes, high cost of installation.

15

What are the disadvantages of oil mist lubrication?

Difficult to set flow rates, environmental concern (stray mist), sensitive to temperature changes, high cost of installation.

16

______________ lubrication commonly saves lubricant, saves energy, and improves reliability where such systems can be used.

Mist

17

The principle of oil mist operation is based on the ability of oil particles to be ________________ by impact on a surface at high velocity.

Reclassified

18

What are some advantages of oil mist lubrication?

Constant supply of fresh lubricant Slight pressurization reduces contamination, No moving parts, Alarm systems monitor flow and oil level, Low lubricant consumption, Lower bearing temperatures due to lower internal friction, Prevents moisture intrusion.

19

What are ten extra costs incurred when high oil losses are tolerated?

1. Cost of replacement lubricant 2. Cost of catching the spilled lubricant 3. Waste oil disposal cost 4. Environmental cost 5. Cost of in-plant transfer and resulting empty drums 6. Extra drum disposal cost 7. Temptation to switch to cheaper lubricant 8. Extra labor involved to maintain oil level 9. Shorter equipment life due to poor in service maintenance 10. Shorter equipment life due to lubricant starvation 11. Substitution of product due to emergency fill operation 12. Housekeeping costs.

20

What are three reasons why bulk packaging reduces costs?

Reduced transportation costs
reduced repackaging (labor)
lower disposal costs
potential for discounts
minimizes storage
reduces inventory

21

Above ground oil storage tanks should have _________ to contain spills.

Dikes

22

Name four financial justifications for purchasing a new lubrication system such as an automatic dispensing system.

Reduces lubricant consumption, longer equipment life, reduced maintenance, reduced contamination.

23

List five goals of an oil conservation management program.

Reduce volume used
segregate used oils
reprocess used oils
minimize wastewater contamination
minimize environmental impact

24

A five gallon pail of oil weighs approximately _________ lbs.

40 pounds

25

How does an empty drum weigh?

36 - 38 pounds

26

Drum inventory should be handled on a ________ ____________ __________ ________ inventory basis.

First in
First out

27

Name six types of automatic lubricating systems.

Oil mist
circulating oil
single line grease
multiple line grease
electro-luber
spray

28

What are three components of most large circulation oil systems that help prolong the useful life of lubrication oils?

Coolers
filters
reservoirs designed to let air dissipate and water to drop out

29

What is the difference between a direct and indirect lubrication system?

In a direct system, a pump is used to meter the lubricant.
In an indirect system, the pump builds pressure and metering valves in supply lines meter the amount of lubricant.
