This is how I disassemble model 10 pin but I don't know for sure if the 110 pin is the same. I start by measuring the pin, tip to back and note the dimension for use when assembling.
Presuming the bolt is apart, place the bolt head on the work bench with the bolt face down. Put the pin into the bolt head. Grip the spring tightly (you might want to wear gloves) and force it downward as you loosen the rear nut.
Be sure to put the parts back in the same order and orientation. Assembly is reverse of disassembly, and don't forget you will set the pin protrusion first. It's easy with the bolt head off the bolt body.
I hope this helps.
