Product Details
This kit from S&S Cycle gives you a standard size replacement breather gear for your 1948 to early 1977 Big Twin motorcycle. It also includes a full set of shims, ranging from .100" to .170" in .010" increments. These shims are crucial for correctly setting the spacing of the breather gear within the engine case, especially if the original hole has been modified. Getting this spacing right is important for proper engine function.
The standard size gear is designed to fit cases where the original breather gear hole hasn't been altered. By using the included shims, you can fine-tune the gear's position to ensure it meshes correctly and operates smoothly. This attention to detail in the kit helps ensure a solid replacement for your drivetrain.
