Wacker Neuson 5000112151 S Type Crankshaft

The Wacker Neuson S Type Crankshaft is a genuine OEM component designed for the GV3800 Value Portable Generator and BT48A. As a factory-sourced part, it is manufactured to the same specifications as the original, ensuring a direct, correct-fit installation with no guesswork. This crankshaft is the right choice when rebuilding or restoring engine function on compatible Wacker Neuson equipment. Confirm your model number against the fitment data before ordering to ensure this is the correct crankshaft for your machine.

Key Features

• Genuine OEM Construction — Machined to original engine tolerances, delivering the dimensional accuracy and material hardness a crankshaft demands for smooth, balanced rotation under load.
• S Type Configuration — The S Type crankshaft profile matches the original engine geometry exactly, allowing straightforward installation into the crankcase without reworking bearing seats or counterweights.
• Verified Fitment — Confirmed for the GV3800 Value Portable Generator and BT48A; always cross-reference your machine's model and serial number before ordering.
• Engine Performance Integrity — A sound crankshaft converts piston energy into usable rotational output efficiently; a worn or damaged crankshaft causes vibration, power loss, and accelerated bearing wear throughout the engine.
• Direct Manufacturer Sourcing — Backed by Wacker Neuson's parts supply chain, this component carries the same part number used by authorized service centers, making it straightforward to verify against service documentation.

The crankshaft is the central rotating component of a four-stroke engine. It converts the up-and-down motion of the pistons into the rotational force that drives the machine's output — whether that is powering a generator's alternator or driving compaction equipment. A crankshaft that is worn, cracked, or out of spec will introduce vibration, reduce power output, and place excessive stress on connecting rod bearings and main bearings. Replacing a failed crankshaft with a correct OEM-spec part restores proper engine balance and full power delivery.
