Kubota Engines for the Oil & Gas Market (PDF)
Made to thrive in challenging environments.
Kubota engines deliver durability, versatility and flexibility for wellhead gas operations.
Zero-Maintenance Valve Timing Control
Standard on Kubota WG2503 and WG3800 engines, the rugged helical front gear train is a zero-maintenance, heavy-duty valve timing control that is superior to timing belt or chain designs.
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.
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 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, providing a turnkey engine solution that meets current emissions regulations.
A knock sensor in WG2503 and WG3800 engines protects from damage caused by detonation or knock caused by fixed spark advance.
The coil-on-plug design on Kubota WG2503 and WG3800 engines eliminates spark plug wires, increasing reliability and lowering your maintenance costs.
