The Multiquip 71428421710 Crankshaft Assembly is a genuine OEM component designed for MT76D and MT86D rammers. As a direct Multiquip OEM part, it is manufactured to the exact tolerances required to keep your rammer operating at full compaction force and consistent stroke rate. This assembly is confirmed to fit the MT76D and MT86D tamper models, making it the straightforward choice when your machine needs a crankshaft replacement. Sourced directly through authorized Multiquip distribution, the part is the correct part for these machines with no guesswork required.
Key Features
- Genuine OEM Crankshaft Tolerancing — Manufactured to Multiquip's exact dimensional specifications, ensuring the correct stroke geometry and bearing journal fit for full compaction output.
- Direct Drop-In Replacement — Engineered to install directly into MT76D and MT86D rammer housings using the original mounting points and bearing configuration.
- Confirmed Fitment — Verified for MT76D and MT86D tamper models; check your model code before ordering to ensure an accurate match.
- Restores Full Stroke Performance — A worn or damaged crankshaft causes loss of impact energy and erratic compaction stroke; replacing it with this assembly brings the rammer back to rated compaction force.
- Long-Term Engine Integrity — Correct crankshaft geometry protects connecting rod alignment and reduces wear on adjacent engine components over extended use.
The crankshaft assembly is the core rotating component inside the rammer's engine, converting the reciprocating motion of the piston into the mechanical stroke that drives the tamper foot into the ground. On a rammer like the MT76D or MT86D, the crankshaft must maintain precise balance and dimensional accuracy to deliver consistent impact energy with every cycle. When a crankshaft wears, cracks, or develops bearing journal damage, the result is reduced compaction force, increased vibration, and accelerated wear throughout the engine — making timely replacement critical to keeping the machine effective and safe on the jobsite.
