What would cause forced deterioration ?
Forced Deterioration
• Sources – Vibration – Wear – Dirt – Dust – Debris
•Countermeasures Tightening Lubrication Cleaning
Aim of Autonomous Maintenance is to move the forced deterioration line closer to the natural deterioration line.
Combination Of Breakdown Causes •Five requirements for zero breakdowns:
1. Maintain basic conditions
2. Maintain operating conditions
3. Restore deterioration 4. Correct design
weaknesses 5. Improve operating &
maintenance skills
Basic conditions neglected
Inadequate skills
Inherent design weakness
Deterioration unchecked
Operating standards not followed
7 Steps for PM
Types of Maintenance
• Breakdown Maintenance - Intentional, not unplanned
• Periodic Maintenance - Time-based or Inspection & Repair
• Predictive Maintenance - CBM, use of technology for assessing condition
• Corrective Maintenance - Recurrence prevention
Responsibility for Maintenance

Example Criteria for Evaluating Equipment
To decide which equipment receives planned maintenance
Equipment Ledger Control
(Page 30 PM)
• Equipment logs are raw data for evaluating equipment. Must have design data and show equipment’s operating and maintenance history.
• Collect all data on the
failures/breakdowns, which caused production loss and analyse

Equipment Clarity Classification
• Evaluate each piece of equipment in terms of its effect on safety, quality, operability, maintainability, etc. • Rank equipment (as A, B, or C, for example) and perform maintenance on all units ranked A or B, as well as those for which zero failure is a legal requirement.
Critical Ranking and Maintenance Method
(Page 33 PM) • Rank failures as major, intermediate, or minor depending on their effect on equipment.
