The Wacker Neuson Balancer Drive Gear is a genuine OEM component designed for CT36 and CT48 series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this part carries the exact specifications required for your machine, ensuring it installs and operates exactly as the original equipment intended. Fitment covers a broad range of CT36 and CT48 trowel variants, including AGP, AGT, ADP, ADT, and AVP/AVT variable-speed models. Confirm your model number before ordering to select the correct configuration for your machine.
Key Features
- Genuine OEM Gear Tolerancing — Manufactured to Wacker Neuson's original tooth-profile and hardness specifications, so mesh engagement and load transfer match the original drivetrain design.
- Direct Drop-In Installation — Engineered to the original shaft interface and gear dimensions of the CT36 and CT48 trowel balancer assemblies, fitting without modification to mounting points or adjacent components.
- Broad CT-Series Compatibility — Covers CT36 and CT48 walk-behind trowel families across standard, CE, and variable-speed configurations, including AGP, AGT, ADP, ADT, AVP, and AVT variants.
- Smooth Trowel Head Operation — A correctly functioning balancer drive gear maintains even torque distribution to the trowel blades, supporting consistent finish quality across the full working pass.
- Verified Wacker Neuson Part Number — Part number 5000081668 is the genuine OEM reference; cross-check against your machine's parts manual to confirm the correct replacement before installation.
The balancer drive gear is a critical component within the trowel's gearbox assembly. It transfers rotational force from the engine through the balancer shaft to drive the trowel blade spider, maintaining the correct blade speed and rotation that produces a flat, densified concrete surface. When this gear wears or chips, it causes uneven blade speed, vibration, or a complete loss of drive — resulting in an inconsistent finish and potential damage to surrounding drivetrain components. Replacing a worn balancer drive gear promptly restores smooth power delivery and protects the gearbox from accelerated wear.
