Bell 206 Driveshaft Coupling Grease Tool

thingiverse

This device is engineered to apply a consistent, precise amount of lubricant to the splines within the tail rotor driveshaft couplings on the Bell 206 helicopter. Data was collected from the BHT service manual, yet while standard tools employ only one surface area, this tool utilizes four distinct faces. This design enables users to effortlessly operate the device and maintains perfect alignment within the coupling, ensuring thorough coverage. To utilize this tool, simply insert it, rotate it, and then remove any excess lubricant. The handle of the device was created using Neon22's "Customizable Profiled Handle" (available at http://www.thingiverse.com/thing:923244). It is recommended to print the tool upright with supports in place, allowing for some cleanup afterwards. This approach yields a smooth, attractive finish on the finished product.
