I am in the process of disassembling a 1959 Emil J Paidar barber chair, Style #573. My purpose is to decrease the weight so it can be more easily moved to a new location. I will also be polishing the chrome, cleaning the leather and porcelain, etc. This is the chair prior to disassembly:

Current status of disassembly is:

When I attempt to lift the pump/piston/cylinder assembly out of the base, it does not come out all of the way:

I suspect that the cylinder is bolted to the bottom of the base, but I do not want to turn the assembly over to verify. Looking down into the assembly, I see three bolts:

My thinking is that if I remove the three bolts I will able to lift the internal pump, and maybe also the piston, out of the outer cylinder, leaving the oil inside. This will leave me with two pieces that I can then more conveniently move down a flight of stairs. Unfortunately, I have been unable to find any drawings of the chair that might give me more insight. I don't want to remove the three bolts if there is a danger of causing problems with the internal assembly of the pump, which presently works well. For the same reason, I am hesitant to remove the pump handle and its connections to the piston.
If anyone reading this post has any experience with the disassembly, or pertinent knowledge based on similar systems, I would appreciate hearing from you.
Thanks,
Bob J
