The Multiquip 71425023600 Crankpin Bearing is a genuine OEM component designed for MT76D and MT-86D series rammers. As a factory-sourced part, it meets the original engineering tolerances required to keep the rammer's crankpin assembly operating within specification. This bearing is a direct-fit replacement for MT76D and MT-86D units, making it a straightforward service part for technicians and operators handling routine maintenance or repair. Sourcing the correct OEM bearing ensures the crankshaft and connecting rod interface is restored to its original operating condition.
Key Features
- OEM-Grade Tolerance Control — Manufactured to the original bearing load and dimensional specifications that the MT76D and MT-86D crankpin assembly depends on for proper rotation and load transfer.
- Direct Crankpin Interface Fit — Engineered to seat correctly at the crankpin journal, maintaining the correct clearance between the connecting rod and crankshaft without adjustment.
- Confirmed Fitment for MT76D and MT-86D Rammers — Verified compatibility with both MT76D and MT-86D Multiquip rammer models, so you can order with confidence.
- Protects Impact Consistency — A properly functioning crankpin bearing sustains the smooth conversion of rotational motion into the rammer's vertical compaction stroke; a worn bearing introduces slop that degrades impact force and compaction quality.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part number 71425023600 carries the same quality standard as the original component installed at the factory.
The crankpin bearing sits at the junction between the crankshaft's offset pin and the connecting rod in a rammer's drive assembly. Its job is to allow the connecting rod to rotate smoothly around the crankpin as the engine converts rotational power into the up-and-down ramming motion that compacts soil. When this bearing wears or fails, increased friction and play at the crankpin cause uneven stroke delivery, audible knocking, and accelerated wear to surrounding components — making timely replacement critical to keeping the rammer performing at full compaction capacity.
