Advice Needed - J Head \ Wades Extruder

Hi All,

I am collecting parts to make a Prusa i3 and have a question on extruder\hotend assembly that I hope one of the guru's out there can help with.

I have a J-Head that I purchased assembled from Banggood that looks like the attached picture and a wades hinged extruder, picture also attached. I have a U plate\clamp to mount the J-Head but nothing is going to fit without removing the brass end with blue PTFE bits on the end. If I take this bit off, do I need to do anything to the hotend carrier, like add anything back in?

Any advice would be appreciated, thanks.

That brass piece is for a Bowen type extruder, I believe there is a threaded insert that goes where that fitting is to keep a PTFE liner in place for use with a Wades.

Thanks for the reply

Normally a short M8 hex socket grub screw were the socket goes all the way through and thin brass washer so it doesn't chew up the PTFE.

Based on this blog posting, I think that the odds are pretty high that there is no PTFE liner in that cloned J-Head:
