i3 MK3S+ need upgrade to B7 extruder body?

I just purchased a new i3 MK3S+ along with a new MMU2S. I purchased they assembled printer, and now I’m assembling the MMU2S. The first thing in the assembly guide is the upgrade of the extruder body from B6 to B7. How can I tell which extruder body I have? I’d much rather not have to go through the process of upgrading this if the new printers being shipped out currently already have this extruder body. Can someone please tell me an easy way to identify which one I have?

You should only need to install the chimney in a new printer. Follow the "A" chapters to disassemble/assemble the extruder if the printer is the i3 MK3S+:

Topic starter answered:
B7 extruder body?

So does this mean I already have the B7 extruder body?

RE: B7 extruder body?

If your printer is an i3MK3S+ the only thing you need to do for the extruder is follow the instructions in the "A" chapters linked above.  The B6->B7 upgrade is for older MK3 and MK2.5 printers.  Ignore those chapters.
