The Multiquip 1C01013150 is a genuine OEM Valve Stem Seal D905-Ebg2 designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. As a direct OEM replacement, this seal is sourced to the original specification, ensuring a correct fit within the engine assembly. Sourced through authorized Multiquip supply channels, 1C01013150 is the part number to call out when ordering for DLW400ES family machines.
Key Features
- OEM-Grade Sealing Material — Engineered to the same material and compression specification as the original, maintaining consistent valve stem oil control across the engine's operating temperature range.
- Direct Engine Drop-In — Matches the original seal profile and seat geometry for the D905-Ebg2 engine, installing exactly as the factory component without reworking the valve stem or guide.
- Confirmed Fitment — Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 Multiquip diesel light welders; verify your model before ordering.
- Protects Engine Oil Consumption — A properly seated valve stem seal prevents oil from migrating past the valve stem into the combustion chamber, keeping oil consumption in check and exhaust clean.
- Fuel System Safety Compliance — Maintaining an intact valve stem seal supports proper combustion chamber integrity, reducing the risk of oil contamination in the combustion process on diesel-powered equipment.
A valve stem seal sits at the top of each engine valve guide and controls the thin film of oil that lubricates the valve stem as it moves up and down. When this seal is in good condition, it meters just enough oil to keep the stem lubricated while preventing excess oil from being drawn into the combustion chamber. When a valve stem seal hardens, cracks, or wears out, oil passes the guide and burns off during combustion — resulting in blue smoke from the exhaust, elevated oil consumption, and potential fouling of spark or glow plugs. Replacing a worn seal promptly restores proper lubrication control and protects the engine from further internal wear.
