The Wacker Neuson Connecting Rod Bushing is a genuine OEM Connecting Rod Bushing designed for a wide range of Wacker Neuson compaction, trowel, and cutting equipment, including the RD12A-90 Tandem Roller, CRT36-26A Trowel, CRTv36-26A Trowel, BFS 2020AS Saw, GS12Ai, and GPS9700A. As a genuine OEM part, the is manufactured to the same tolerances and material specifications as the original component fitted at the factory. This bushing is a direct-fit replacement, allowing technicians to reinstall with confidence across every listed model variant. Verifying your machine model and serial number against the fitment list before ordering ensures a correct match every time.
Key Features
- OEM-Grade Bearing Surface Integrity — Manufactured to Wacker Neuson's original bore tolerancing and material hardness specifications, maintaining the precise clearance required between the connecting rod and crankpin.
- Direct-Fit Installation — Engineered to the same dimensional profile as the original bushing, seating correctly into the connecting rod bore without rework or machining.
- Broad Model Coverage — A single part number covers the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Trowels, BFS 2020AS Saw, GS12Ai, and GPS9700A, making it a versatile stocking item for mixed fleets.
- Protects Engine Longevity — A correctly fitted connecting rod bushing maintains proper oil film clearance at the small end, preventing metal-to-metal contact that leads to accelerated wear on both the rod and crankpin journal.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson authorized parts network, ensuring the 5000226421 meets all original design and material standards for these machines.
The connecting rod bushing is a small-end bearing sleeve pressed into the eye of the connecting rod, where it forms the interface between the rod and the piston pin. Its job is to allow smooth, low-friction rotation of the piston pin under the high cyclic loads generated during combustion, while retaining a consistent oil film to prevent direct metal contact. When this bushing wears or fails, clearance increases beyond tolerance, producing a characteristic knock, accelerating wear on the piston pin and rod, and ultimately risking catastrophic engine damage if left unaddressed.
