Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original thread and material spec for the D902 engine, ensuring a leak-free seal at the oil gauge port.
- Direct Engine Application — Engineered specifically for the D902 diesel engine found in the DLW400ES, DLW400ESA, and DLW400ESA1 light welder units — threads in without modification.
- Correct Oil Monitoring Function — A properly seated oil gauge plug maintains accurate crankcase pressure and allows reliable oil level checks, preventing premature engine wear.
- Confirmed Fitment — Verified for DLW400ES series machines; cross-reference part number 1G51336550 against your machine's parts diagram before ordering.
- OEM Supply Chain Sourcing — Fulfilled through authorized Multiquip parts distribution, so you receive the same component installed at the factory — not a generic substitute.
The oil gauge plug seals the oil gauge port on the engine crankcase, preventing oil leaks and maintaining proper internal pressure within the lubrication system. On the D902 diesel engine, a damaged, missing, or improperly fitting plug can result in oil loss, contamination, or inaccurate oil level readings — any of which can lead to accelerated engine wear or unexpected shutdowns. Replacing a worn or stripped plug with a correct OEM part like the 1G51336550 restores the integrity of the engine's oil system and supports continued reliable operation of the welder.
