• Optimal performance: proper lubrication makes sure that moving parts operate smoothly, prevent frictional
wear and buildup, which can prevent equipment’s for the failure.
• Extended lifespan: continues maintenance helps to extend the lifespan of machinery by reducing wear and
tear on components, preserve their functionality over time.
• Efficiency: for operate more efficiently, of any system that are well-lubricated for consuming less energy and
reducing operational cost.

• Safety: properly lubricated system contributes to a safer work environment by decreasing the risk of accident
and malfunction caused by equipment failure.
• Diagnosis of issues: continues inspection and diagnostics allow for the early deduction of problems such as
leak, contamination or improper lubricated, preventing more serious issues down the line.
• Component integrity: servicing lubrication system components such as filters, pumps, hoses, and reservoirs
ensure their integrity, preventing failures that could disrupt operations.
In summary investing maintenance, diagnosis, and servicing of lubrication system is essential for maximizing
equipment performance, longevity, efficiency, and safety in industrial setting.

Causes of failure of the lubricating system and its

components

Objectives: At the end of this lesson you shall be able to
• demonstrate causes of failure of the lubricating system and its components.

Causes of failure in lubricating system
1 Lack of oil in the sump.
2 Oil is too thin

3 Main and big end bearings are worn out.
4 There is leaking in the oil routes.
5 Pressure relief valve is faulty.
6 Oil pump is faulty.

7 Main oil gallery is closed.
8 Oil pressure gauge is faulty
9 There is more thick oil in the sump.
10 Relief valve is not arranged properly.
11 Wear of piston ring.

12 Engine bearings are worn.
13 Wear and tear in the cylinder.
14 Engine oil seal is leaking.
Causes of failure in lubricating system components
1 In oil pump

• Oil pump wear: over time the inner parts of oil pump like gears, bearings, etc. wear due to normal use
every day which results in oil pump wear
• Sludge Formation: oil can’t be thin and viscous every time and it losses it’s viscosity which then accumulated
and create a sludge resulting in clogging of oil pump.
