Identify the front nut and drive version

Check the drive identification, propeller type and front nut against the required tool reference. Front and rear propeller fasteners can use different arrangements, and this listing does not establish that the tool serves every nut on the drive. Confirm DPR applications against the installed hardware and the listed 21318669 reference as well.

Compare the nut's engagement features with the tool rim and check clearance over the surrounding shaft and hardware. Confirm the square-drive size before selecting a handle. Tool length, outside diameter, bore and notch dimensions are unspecified. Fit for SX or other DuoProp drive families has not been established.

Use the drive's propeller-service instructions

Follow the drive manufacturer's instructions for access, nut removal and reassembly, including the required tightening value and locking components. Check that the tool seats fully on the correct nut before applying force. It serves the nut-engagement step; extracting a seized propeller may require separate equipment. Inspect the tool's drive opening and rim for damage before use.
