53: Repair Implementation Issue
Definition/Typical Issues
Was the corrective maintenance repair performed incorrectly?
Examples
Example 1
- An inexperienced mechanic incorrectly repaired a pump seal, which subsequently leaked. He inserted one of the rubber seals backwards. The procedure provided no guidance other than to "install the rubber seals."
Example 2
- During corrective maintenance, mechanics identified a problem with a seal on a pressure transmitter. To correct the problem, a new rubber gasket should have been installed. However, the mechanic would have had to go to the warehouse to get a new gasket and it was close to quitting time. Instead, the operator applied a sealant to the gasket. This caused problems during subsequent repairs when the old seal could not be removed.
Example 3
- Condition-based monitoring of a pump indicated an upcoming failure (e.g., from condition-based maintenance monitoring). Corrective maintenance was initiated to repair the pump. The pump was repaired incorrectly.
Typical Recommendations
- Review maintenance procedures to ensure that they provide adequate guidance based on the experience level of personnel.
- Provide training for personnel on repair techniques.
- Perform field inspections to identify troubleshooting/corrective action maintenance tasks that are not being properly implemented.
- Review maintenance records to assess the effectiveness of the troubleshooting/corrective action maintenance program.
