The Wacker Neuson Crank Gear is a genuine OEM component designed for the BH 23, BH 55, and BH 65 series gasoline breakers. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a correct fit across the wide range of BH-series tool holder configurations it covers. This Crank Gear is an essential drive component within the breaker's reciprocating mechanism, and sourcing the genuine Wacker Neuson part means you can trust the dimensional and material tolerances are exactly as the machine demands. Confirm your model number against the fitment list before ordering to ensure compatibility with your specific BH 23, BH 55, or BH 65 variant.
Key Features
- Genuine OEM Gear Tolerancing — Manufactured to the original tooth profile and hardness spec, ensuring proper mesh and load transfer within the breaker's drive train.
- Direct Replacement Fit — Installs into the crank housing the same way as the original, with no re-clocking or adaptation needed to seat correctly.
- Broad BH-Series Coverage — Confirmed fitment across BH 23, BH 55, and BH 65 gasoline breaker models, spanning multiple tool holder sizes including 27x80, 25x108, 28x152, 28x160, and 32x160 configurations.
- Sustained Strike Energy — A correctly functioning Crank Gear maintains consistent rotational-to-reciprocating motion conversion, preserving the breaker's rated impact force and blow frequency.
- Wear-Critical Component — Gear tooth wear or chipping directly degrades strike consistency and can cause secondary damage to the crank assembly; replacing at first sign of wear protects the broader drivetrain.
The Crank Gear is a core element of the gasoline breaker's internal drive mechanism. It converts the engine's rotational output into the reciprocating motion that drives the chisel or tool bit, and it must maintain precise gear engagement under the high cyclic loads these machines produce. When the Crank Gear wears, chips, or fails, strike energy drops off noticeably, the breaker may run roughly, and continued operation risks damaging adjacent components in the crank assembly. Replacing it with a genuine Wacker Neuson part like the 5000106403 restores the correct drive geometry and keeps the breaker performing as intended.
