Oil Pressure Relief Piston Valve - L6-226 Engine

This model prints a DRAFT model of the oil pressure relief piston used in the Willys L6-225 engine in order for you to confirm fit and function. You will need to have this part printed or milled in metal of your choice for use in your engine (likely using a third-party printer service such as https://www.pcbway.com/) once you have verified suitability for your application.

This part is specific to the Willys L6-226 engine (used in Willys vehicles from 1950 - 1964 (primarily wagons and pickups). Unfortunately this part is no longer available from parts suppliers. 

I have included the original CAD file created in FreeCAD so that you can adjust any parameters needed to tweak this design (if necessary) for your particular situation:

To modify this model (if needed), follow these instructions:

• Download FreeCAD (https://www.freecad.org/) and install it on your computer.
• Download the .FCStd file I have included (Oil Pressure Relief Piston VARIABLES v2.FCStd) from MakerWorld and open it in FreeCAD.
• Click once on the “{VarSet}” line (on the left side in FreeCAD), and then adjust the parameters underneath (if needed) to fit your requirements. Note you can rotate by clicking on the “cube” in the top right to see your changes. (See included photo of available parameters).
• Then choose “File…Export” and choose “STL" (or “STEP” if you prefer)
• Go into Bambu Studio and select “File…New Project”
• Then select “File…Import” and adjust so the chisel base is on the bottom (no supports are needed), then slice and print as normal.
• Once your are satisfied and have confirmed fit and function, work with a third-party provider (such as https://www.pcbway.com) to produce a final print in the metal of your choice.

DO NOT use a 3D printed plastic part in your engine.
