Can someone please explain the lubricate the needle bearings on the guidler idler part of the build manual? Is there any specific way that the needle bearings should be placed in the idler gear? How do you lubricate them? Thanks for any help!

@dapper ice I typically put the needle bearing inside of the gear, and then pack it with the same grease I use for my rails. I'll put my finger over the far end, and use the 20mm pin to press the grease into bearings. I'll repeat this a few times, making sure to spin the 20mm pin a few times until it feels and looks completely covered. I'm sure others probably have a better way, but it hasn't failed me yet, just a bit messy. I typically have my ep2 stuff in a syringe like this (https://west3d.com/products/mobil-mobilux-ep2-10ml-filled-syringe-with-blunt-tip?_pos=2&_sid=e91a1e6a0&_ss=r) that makes it easy to get it inside of the combined parts.

Does it matter which way the needle bearings are aligned inside the idler?

They only really go in one way
