Plug In Fuse Piston Pin Tool

thingiverse

This is a tool called a "Plug In Fuse Piston Pin" to install a piston pin retainer (on both side of a piston pin). The piston pin connect the con rod to the piston. Without this tool, it's **extremely** hard to install the pin retainer. More or less modeled after the KTM special tool 77329030100. Here is the instruction to use, per the KTM repair manual, so that (in conjonction with my pictures) you can better understand its use: 1. Position piston ring lock. 2. Insert the special tool and firmly press it toward the piston. 3. Turn the special tool clockwise, thereby pressing the piston pin retainer into the groove. 4. Make sure that the piston pin retainer is seated correctly on both sides. This object was made in Tinkercad.

Haven't tried to print this one though but it shouldn't be any different)
