Alcatel Adixen 2021i Pump Rebuild

I purchased a used Alcatel Adixen 2021i. I got it for super cheap and considering how cheap, I assumed it would need a rebuild. It pulled down to a max of 600 microns after multiple oil changes and a kerosene flush. So here I am. I’ve ordered the complete rebuild kit but can very few resources on how to attempt this process. If anyone has any recommendations, they would be greatly appreciated. I was able to find a pdf which has some instructions (p.90), but I would like a second opinion or some…

Read this entire thread and you’ll get it. I know the title is about rebuilding an Alcatel, but about 1/3 of the way in we discuss staging your pumps
