An MWM gas generator is a significant investment. Like all high-performance machinery, it delivers its best performance and longest service life only when maintained according to a structured schedule. In Bangladesh’s industrial environment — where generators often run 16–24 hours per day — maintenance is not optional.
Why Regular Maintenance Matters
A well-maintained MWM generator can operate reliably for 80,000–100,000 hours over its lifetime. Neglected maintenance accelerates wear, increases fuel consumption, raises the risk of catastrophic failure, and voids manufacturer warranties.
MWM Generator Maintenance Schedule Overview
- Every 500 Hours: oil & coolant check, air filter inspection, spark plug visual check, belt inspection
- Every 1,000 Hours: engine oil & filter change, lube oil filter, air filter, ignition inspection, sensor calibration
- Every 4,000 Hours: spark plug replacement (OEM Prechember), valve clearance, fuel system, turbocharger, heat exchanger
- Every 8,000 Hours: cylinder head inspection, injector/actuator calibration, cooling overhaul, control update
- Every 30,000–60,000 Hours: major overhaul — full engine rebuild, piston & cylinder liner replacement, crankshaft inspection
Key Spare Parts to Keep in Inventory
- MWM UPF Oil Filter, Lube Oil Filter, Air Filter
- Spark Plugs (Standard & MWM Prechember Genuine)
- Ignition Cables
- O-seals and O-rings
- Coolant additives
Annual Maintenance Contract (AMC): Is it Worth it?
For continuous operations, an AMC with Gen Power Equipment Ltd. is highly recommended. Benefits include fixed annual cost, priority emergency response, discounted OEM parts, dedicated service engineer assignment, and quarterly performance reports.
Common MWM Generator Problems in Bangladesh
- High gas consumption — usually delayed spark plug replacement or miscalibrated actuator
- Overheating — clogged heat exchanger or low coolant
- Control system faults — aging TEM Evolution CPUs or Heinzmann actuator issues
- Vibration — worn engine mounts or imbalanced turbocharger
