Koken Piston Extraction

07/13/2012 4:39 PM

I've got a 1965 koken barber chair. I've taken it down to where the only thing left is to extract the piston from the base,that way I can easily move it into place,replace the oil and after cleaning all componants put it back together. What position does the handle have to be in before I extract the piston? Do I have to pump it all the way up first? I've been to a lot of places looking for an answer and you gentlemen seem to know which trail to take. Walt

you have been asking us how to rebuild this chair for months. why did you decide to tackle this job yourself when you obviously don't have a clue what you're doing?

check the yellow pages ."hydraulics".

i apologize for being so blunt. having rebuilt a barber chair myself, i understand the problems trying to find information in/re to these old chairs.

have you tried talking to an old barber in your area?

most of these these pump action hydraulic cylinders appeared to be simular and possibly only made my a few companies. they may have had one of their chairs repaired and know who can repair it.

often there are collector clubs that specialize in these sort of things.

if you can can be more precise about the info you need, such as date, md.#, and any other pertinant information, i'm sure our members will make every effort to help you.

again, i appologize. please don't judge this blog because of my crass reply.

we can't help without all the info. most of us are specialists in different fields of expertise. i'm sure that someone can lead you in the right direction.

good luck.

I guess it is a little lat for this, but, welcome to the insanity. Please cut the duck a little slack. He was just "discussing" the inflated prices of heating oil, and it seems his feathers may have gotten a little ruffled.

While I am no expert on your old barber chair, I do understand basic hydraulics. I would have suggested that you simply pump the handle to raise it, and see what stops the piston from extending any further. My guess would be a snap ring. If you search the side bar for subjects that interest you, and browse a little, I am sure that you will find out that the strength of this site is the vast knowledge that visits and comments here. There are some true geniuses here, and some people with just plain old good sense. But it is always an interesting day at CR4. Sit back and take the tour, and enjoy the ride. Now that you have joined, feel free to comment on any subject that catches your fancy.
