The Wacker Neuson Crankcase Cover Complete is a genuine OEM component designed for the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Trowel series, and the GS12Ai. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a drop-in fit with no guesswork on installation. This complete cover assembly ships as a finished unit, so everything needed to restore proper crankcase sealing is included. If your machine is showing signs of oil seepage, engine contamination, or external damage to the cover, replacing it with the correct Wacker Neuson part is the straightforward fix.
Key Features
- OEM Sealing Integrity — Manufactured to match original material thickness and sealing surface geometry, maintaining the crankcase environment the engine was designed to run in.
- Complete Assembly — Supplied as a finished Cover Complete unit, so the cover and associated hardware arrive ready to install as a single assembly.
- Broad Series Fitment — Verified for RD12A-90 Tandem Rollers, CRT36-26A and CRTv36-26A Trowel models, and the GS12Ai, covering a wide range of Wacker Neuson compaction and finishing equipment.
- Engine Protection Restored — A correctly fitted crankcase cover keeps oil in and contaminants out; a cracked or damaged cover risks oil loss and accelerated engine wear.
- Exact Part Number Match — Ordering by OEM part number 5000226407 confirms you are receiving the correct cover profile and fastener pattern for your specific machine configuration.
The crankcase cover seals the lower engine assembly, keeping engine oil contained and preventing dirt, debris, and moisture from entering the crankcase. It works alongside gaskets and seals to maintain the pressurized lubrication environment that protects internal engine components during operation. When the cover is cracked, warped, or compromised, oil can leak externally or contaminants can work their way inside — either condition leading to lubrication failure and potential engine damage if left unaddressed.
