What is Preventive Maintenance?

To perform proactive maintenance under a plan schedule to prevent unnecessary breakdown

Importance of Preventive Maintenance • prevent unplanned breakdown

• reduce maintenance cost

• increase machine reliability and availability

Preventive Maintenance Schedule

• Plan A – 250 hrs

• Plan B – 500 hrs

• Plan C – 1000hrs

• Plan D – 2000hrs

* Remark: For new machine 50 hours machine warranty maintenance

to be carry out after handing over – according to Plan C and includedadjusting engine valve tappet clearance

10) Check Turbocharger and Exhaust fo

• Check that the oil line to and from the turbocharger do not leak

• Check that all connection between

the turbo and inter-cooler do not leak. Renew all broken gasket seals and studs to confirm gas tight between connection

• Pressure may build up in a blocked

crankcase vent. This may force oil into the inlet air system of the turbocharger and engine
