The Multiquip 1628504460 Oil Seal is a genuine OEM component designed for DLW400ES series diesel light welders. Sourced directly from Multiquip, this oil seal delivers the exact material grade and dimensional tolerances required to maintain a leak-free engine. It is a direct-fit replacement for the V1305-E2B engine application found in DLW400ES, DLW400ESA, and DLW400ESA1 units.
Key Features
- Genuine OEM Sealing Material — Manufactured to the same compound and compression specification as the original, ensuring consistent sealing performance under engine heat and pressure cycles.
- Drop-In Engine Fit — Engineered to seat correctly in the V1305-E2B engine housing with no reworking of mounting surfaces required.
- DLW400ES Series Compatibility — Confirmed fitment for DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models.
- Leak Prevention Where It Counts — A worn or cracked oil seal allows engine oil to escape the crankshaft or camshaft bore, leading to oil loss, contamination of surrounding components, and potential engine damage during operation.
- Fuel and Oil System Integrity — Maintaining a properly seated oil seal is critical to protecting internal engine lubrication pressure — a degraded seal can cause pressure drop that affects bearing and cylinder wall lubrication.
An oil seal creates a dynamic barrier between a rotating shaft and a stationary housing bore, preventing engine oil from leaking out while keeping contaminants from entering the lubrication system. In a diesel light welder like the DLW400ES series, this seal plays a direct role in sustaining proper oil pressure and protecting internal engine components during extended run times. When an oil seal fails — through hardening, cracking, or lip wear — oil leaks and contamination can follow quickly, making timely replacement essential to engine longevity.
