HELP! ! ! BB thread on my Bianchi
Please help me about this:
I am restoring this Bianchi. Maybe is from 1980's. please see picture1
I was able to take the BB off from this side. please see picture2. to loosen it is counter clockwise.
But on the other side. please see picture3. This cap is so tide! Am I doing the wrong direction to loosen it? Is it also counter clockwise to loose it if I facing it? I don't want to damage it! Anyone has insight about this? THANKS!

On the drive side, it should be counter-clockwise to remove.
Sometimes, a long piece of pipe shoved onto the end of the bottom bracket wrench is necessary to provide enough force.
I'd take it to the LBS if you are stuck. They usually have a special "persuader" tool to get that sucker off.
Or, you can relive what I went through on my Fuso. LINK
Hacksaw, dremel tool, several long screwdrivers and much colorful language was required.

+1 to the LBS. Thats way too nice a frame to screw up with a mistake. Don't feel bad, most of us have been there when it was just too difficult to remove something and needed a really good LBS mechanic to lend a hand. The mechanics I've run into appreciated the vintage ride I had and were very careful with the older frame.

My bb was some aluminum sleeved, exotic brand that resisted all attempts by the LBS to remove it so I took matters into my own hands. The pics are what occurred after many hours of trying to do it correctly.

to the OP: I don't recognize that BB, and it doesn't show any numbers to indicate threading, but a quick check will be the BB shell width: if it's 70mm then you have an Ital BB and that fixed cup will unscrew CCW (regular), if it measures 68mm then it's BSC and you'd unscrew it CW (LH threads, opposite of usual). I'd be surprised if a Bianchi of this vintage has anything other than Ital, but you never know.
Often you can do it by hand if you have a tight fitting spanner with the proper oval opening, use the big bolt with stack of washers to hold the spanner tightly onto the cup(see Sheldon Brown for a pic), smack that spanner with a dead-blow hammer in the proper direction...it's always worked for me, when dealing with a frozen steel cup (alloy cups are another horror show!). Also, you might need penetrating fluid and/or heat to help things along.
