Mitsubishi F4AXX Transmission Pump Alignment Tool

thingiverse

I used an alignment tool to replace a busted transmission oil pump in my F4A51 transmission from a Mitsubishi Galant. The oil pump for this transmission doesn't have any way to attach it to the housing, making it impossible to reinstall without an alignment tool that holds it in place while tightening the bolts. I found out there's a company selling this tool for $80+ dollars, but since I only needed it once, I decided to use my calipers and measure everything myself. After modeling and printing this tool in just a couple of hours, it worked perfectly for me. I've included the model for a short test piece that lets you check if your printed part fits properly in the stator - note that you won't be able to verify fitment on the final tool. Print this first to ensure your printer's tolerances are correct.
