Wacker Neuson 5100006766 Oil Drain Plug M22x1.5

The Wacker Neuson Oil Drain Plug M22x1.5 is a genuine OEM component designed for the RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Hfb, and RD7Hehfb series double drum rollers. Sourced directly from Wacker Neuson, this plug matches the exact thread specification — M22x1.5 — required by the engine oil sump on these machines, ensuring a clean, leak-free seal every time. As a genuine OEM part, the is manufactured to the same standards as the original, so you can complete an oil change or engine service with full confidence in the fit. Keep one on hand as a service spare and avoid the risk of cross-threading or leaks caused by an incorrect replacement.

Key Features

• Correct Thread Specification: — M22x1.5 thread pitch matches the engine sump port exactly on all covered RD7H-series rollers, seating flush without the need for thread chasing or adaptation.
• Genuine OEM Sealing Integrity: — Manufactured to Wacker Neuson's original material and dimensional spec, delivering the same metal-to-metal seal as the factory-installed plug for a leak-free drain point.
• Broad RD7H Series Coverage: — Fits RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Hfb, and RD7Hehfb double drum rollers, making it a practical stock item for fleets running multiple variants.
• Protects Engine Oil System: — A properly seating drain plug prevents oil loss and contamination ingress at the sump; a worn or cross-threaded plug risks undetected oil leaks and potential engine damage during operation.
• Fuel and Fluid System Safety: — A correctly torqued, properly threaded drain plug is a critical seal in the engine lubrication circuit — using the right OEM part eliminates the risk of plug failure under operating pressure and heat.

The oil drain plug seals the engine oil sump, keeping the lubrication system closed and pressurized during operation while providing a clean access point for routine oil changes. On double drum rollers like the RD7H series, maintaining a reliable drain point is essential — even a minor seep at the sump can lead to low oil levels that go unnoticed until engine wear becomes a problem. A worn, stripped, or incorrect plug allows oil to escape and contaminants to enter, so replacing it with the correct OEM part at every service interval is straightforward insurance for long engine life.
