The Multiquip 1G95803040 Complete Cylinder Head D722-E2B is a genuine OEM component designed for the DLW300ES series diesel light welder. Sourced directly from Multiquip, this part meets the exact specifications of the original component fitted at the factory. It is engineered to work with the Kubota D722-E2B engine used in DLW300ES, DLW300ESA, and DLW300ESA1 units, ensuring a direct, bolt-in installation with no guesswork on fit or compatibility.
Key Features
- Genuine OEM Construction — Precision-machined to the same tolerances as the original head, ensuring correct compression ratio, valve seat geometry, and sealing surface integrity for the D722-E2B engine.
- Direct Bolt-In Replacement — Matches the original head gasket surface, port dimensions, and bolt pattern of the DLW300ES series for a straightforward swap without machining or adaptation.
- Confirmed DLW300ES Series Fitment — Verified compatible with DLW300ES, DLW300ESA, and DLW300ESA1 Multiquip diesel light welder models powered by the Kubota D722-E2B engine.
- Sustained Engine Output — A correctly sealed cylinder head maintains proper combustion chamber pressure, supporting consistent power delivery to keep the welder producing stable arc performance under load.
- Critical Combustion Integrity — A warped, cracked, or failed cylinder head leads to compression loss, coolant contamination, and overheating; replacing with a genuine OEM head restores the engine to safe operating condition.
The cylinder head forms the top of each engine combustion chamber, housing the intake and exhaust valves and sealing the combustion gases generated during the power stroke. On the Kubota D722-E2B engine found in the DLW300ES welder, a sound cylinder head is essential for maintaining compression, regulating valve timing, and routing coolant through the head passages to prevent overheating. When the head warps, cracks, or develops a failed sealing surface, the engine will lose power, consume coolant, or fail to start — making prompt replacement critical to restoring full operation.
