# Mechanical - 4x M5x40 (recommended at least M5x45) screws with self-locking nuts - 2x M8 self-locking nuts - M8 (threaded) rod - 4x 608 (8x22x7) 2RS bearings - 7-9 M8x1.5mm washers - 7x5 (or 7x4, because 7x5 is not the best option) **sillicone!** tube (PCV is not elastic enough) # Notes - Place at least 2 washers (sometimes 1 can cause drag) between outside bearing and rotor (to prevent drag) - Place single washer between rotor and internal bearing (they're not visible in F360 screenshots) - Do not overtighten nuts! - Pump was tested on 7x5mm sillicone tube using Parkside 20V Drill, atmospheric pressure was able to push liquid back quite quickly thus I think that using 7x4mm tube might fix that issue - It's a pain to place tube, you can tighten M5 screws a bit and then force tube to locate itself in place between bearings and plastic - You should be able to rotate the internal part using small pliers. # Assembly instructions You can get assembly manual [here](https://drive.google.com/file/d/1sz90wXUt9Y1J_fDZ4CQG58dX8KkZrJVO/view?usp=sharing).
