When making a tool change the tool holders have been hanging up, the problem started slow and progressed to where we cannot make any tool changes.
It seems like the air cylinder hasnt had enough power to press down on the drawbar to make enough travel to change the tool holder or my washers are old and worn.
I replaced all 90 spring washers and havent been able to test them because a new problem has arisen.
Normally I press the tool change button to actuate the air cylinder into the drawbar.
Currently I just turn the air on to the machine and the air cylinder slowly moves into the actuated position and pushes into the drawbar without me pressing anything.
If I remove the air lines going to the (parker pvlb1216067 air valves) there is air coming out of the valves and more air then usual coming out of the exhaust valve. If I depress the tool change button there is a greater spike of air that comes out the valve.
I am wondering if the problem is the air cylinder or the valves,
