WG2503-Petrol / WG2503-Natural Gas
The Kubota WG2503-N-E3 is a 42 kW industrial, natural gas engine. Built to deliver reliable power 24/7 to the operation of wellheads in Australia’s remote and harsh outback. Direct spark ignitions means no distributor, providing less maintenance as well as increased reliability for mining operators. Testing shows Kubota WG engines will save operators 4% per year in fuel costs.
Product Features
Zero maintenance valve timing control
Standard on Kubota WG2503 engines, the rugged helical front gear train is zero-maintenance, heavy-duty valve timing control. It is superior to timing belt or chain designs, which require regular maintenance and can lead to major engine failure. Water-Resistant Ignition-System Connectors. For trouble-free operation in all climates, the state-of-the-art ignition system includes tough, water-resistant connectors to ensure an easy startup, day after day.
Coil-on-plug ignition
The coil-on-plug design on Kubota WG2503 engines eliminates spark plug wires, increasing reliability and lowering your maintenance costs. Kubota spark plug replacement intervals are 2,000 hours.
Knock protection
A knock sensor in the Kubota WG2503 engines protect them from damage by detonation or knock, caused by fixed spark advance. The sensor detects detonation through mechanical vibration in the engine block, cylinder or head. It sends instant feedback to the ignition system in order to retard spark, reduce knock intensity and protect the engine.
Premium Valve Materials with cast iron cylinder head
High-temperature alloy exhaust valves and seats are fitted into our robust cast iron cylinder head for an even more reliable engine life. These wear (and corrosion) resistant parts are especially important for wellhead duty.
Manufacturer of record
Kubota is the manufacturer of record for this family of engines. The benefit to the customer is having a turnkey solution. In fact, Kubota emission levels for this engine line are lower than CARB Phase 3 certified limits.
2-year, 2000-hour limited warranty
Rest easy knowing your Kubota engine is backed by the manufacturer against defects in materials and workmanship for two years or 2,000 hours, whichever comes first.
