Wacker Neuson 5100033182 Sight Glass

The Wacker Neuson Sight Glass is a genuine OEM component designed for the BS50, BS60, BS70, DS70, and AS-series vibratory rammers and diesel rammers. As a direct factory replacement, part installs in the original position with no modification to the housing required, restoring clear, accurate oil-level visibility. This part covers an extensive range of Wacker Neuson rammer configurations — including 2-stroke, 4-stroke, oil-injected, battery-powered AS-series, and diesel DS-series models — making it a go-to service item for fleet operators and rental yards alike. Keep a spare on hand to support routine preventive maintenance across multiple rammer variants.

Key Features

• Genuine OEM Clarity — Manufactured to Wacker Neuson's original optical and dimensional spec, ensuring the lens material delivers undistorted, true-color oil-level readings in field conditions.
• Drop-In Housing Fit — Matches the original thread pitch, diameter, and sealing surface of the rammer crankcase port, so installation requires only standard hand tools and the correct torque.
• Broad Rammer Family Coverage — Confirmed fitment across BS50, BS60, BS70, DS70, and AS-series rammers, spanning 2-stroke, 4-stroke, oil-injected, diesel, and battery-powered configurations.
• Protects the Engine From Oil Starvation — A clear, undamaged sight glass lets operators verify oil level before every shift; a cracked or fogged glass leads to missed low-oil conditions and premature engine wear.
• Seal Integrity at the Crankcase — The OEM-spec gasket or O-ring seating surface prevents oil seepage at the crankcase port — a failure point that can introduce contamination or cause slow oil loss if a substandard replacement is used.

The sight glass gives the operator a direct visual check of the oil level inside the rammer's crankcase or lubrication reservoir without removing any covers or using a dipstick. On vibratory rammers, maintaining the correct oil level is critical — the crankcase lubricates the eccentric mechanism that drives the compaction stroke, and running low causes accelerated wear or seizure. When a sight glass becomes cracked, clouded, or starts weeping oil at its seating, it must be replaced promptly so operators can continue to make accurate pre-operation checks and prevent costly internal damage.
