How to install Miche Primato BB
OK, attached is the picture of the bootom bracket. Step 1 is to screw the RH side, along with the cartridge, counter clockwise into the drive side, and then step 2 is to screw the LH clockwise into the non drive side (its an English thread).
But.... to do this the LH threaded part needs to be removed from the assembly (cartridge).
How do you get LH side off?? It just rotates endlessly if you try and uncrew it. It doesn't seem to want to push off.
(OK, the picture won't attach because its trying to paste as link, and the system wont let me post links... Hopeless!!)

If it's anything like a Shimano cartridge bb, that LH side is interference fit. It should slide off so you can install the RH side.
You might fashion a puller with a bench vise. Position the jaws until they're narrower than the cup but wider than the bracket, and see if a little parallel pressure keeps it from binding up while you slide the cartridge out. Lube won't hurt, either.

But if anyone can confirm the LH cup will slied of a snap ring, that would be great! Cheers...

Cheers John! The BBT-5 fits inside the tabs of the cups. I have that, but it just rotates the cup in place - so it does seem its on a snap ring, not a thread inside (which it could not be because it needs to endlessy rotate in use !)

Use the hands you were born with and pull the cup off.
If that won't work, hold the left cup in your hand and lightly tap the protruding spindle with a hammer or mallet. The cup should pop right off without much fuss.
