Key Features
- Genuine OEM Sealing Material — Manufactured to the original elastomer compound and lip profile specified for these diesel-powered units, maintaining the integrity of the oil boundary under operating heat and pressure.
- Direct-Fit Installation — Matches the original bore diameter and shaft dimensions exactly, seating into position the same way as the factory-installed seal with no rework to the housing.
- Broad Series Coverage — Compatible with DLW300ES/ESA/ESA1 diesel light welders and DAC7000SS, DAC7000SSA, DAC7000SSW, DA7000SSA2, and DA7000SSA2GH super-silent diesel generators.
- Prevents Costly Oil Loss — A correctly seated oil seal keeps lubricant contained within the rotating assembly, preventing oil starvation that can lead to accelerated bearing and shaft wear.
- Verified by Part Number — Cross-referencing part number 1587704140 against your machine's serial plate or parts manual confirms fitment before you turn a wrench.
An oil seal creates a dynamic barrier between a rotating shaft and a stationary housing, keeping lubricating oil inside the assembly while blocking contaminants such as dust, moisture, and debris from entering. In diesel welders and generators like the DLW300ES and DAC7000SS series, oil seals protect critical rotating components within the engine and power-generating end, where consistent lubrication is essential to sustained output and longevity. When an oil seal wears, cracks, or hardens with age, oil migrates past the lip, leading to visible leaks, dropping oil levels, and — if left unaddressed — premature failure of the shaft or bearings it was protecting.
