can anyone tell me where i can find information on how to get the s tube out of a putzmeister TK100. 

Well I am presuming you do not have a manual for the Tk100.  There is only one short page on takeing out the s-tube basicly it says to remove everything from the out let end including the extention.  Also the shift cylinders and bearing from the other end.

I have not yet needed to remove the one in my pump so I can not give you any first hand information.

Is it grouted in place/stuck? Have you tried to take it out? Have you ever removed an 's' tube from a pump? Where are you in all this?

Am I missing something here?  How could it possable take 30 pages to explain how to get the s-tube out?

taking out the s-tube is very easy it can be done in 30 minutes. if you havnt figured it out yet message me and ill tell you how...
