I made one with OEM extruder and now I did one with all metal extruder because the OEM is hard to find if it broke and of the plastic pieces.
Here is the link to when I got this extruder. Amazon Extruder Upgraded Replacement Left Hand
Now when you replaced the extruder you will need to go the E-Steps.
I use the TH3D website to help get the calculation for the E-Steps. ←Link here
Do at your our risk. I will not be responsible for any mistakes that you make or don't get the desired outcome.
I use OctoPrint with Terminal to run the commands but you can use whatever you feel comfortable with.
the commands I run to Extrude 100mm
G91 E0
G1 E100 F100
Repeat the same 2 command as many times necessary to the desired E-Steps.
Just to remember to save after each update of you E-Steps.
Use the information from TH3D to update your E-Steps.
