how to check the accumlator pump for 36 putz 2007?how to check the change over cylinder haydrulic circuit?

That's a very general question.

The best way to help you would be to get your Serial Number and then we need to narrow down the problem with some specifice info.

You can E-Mail me the serial number so we can help

A couple questions for you to start. What is the accumulator pressure set at now ? 

What is the Nitrogen per charge set at ?

If the nitrogen is low the shift can be slower or sluggish.

Is the problem a slow S-Tube shift ? You can also have problems with wear parts binding or worn bearings.

So I will need a bit more to see what direction to proceed .

The problem thai s tube is slow shifiting .Nothing wrong with wear parts we checked and we found that ballon pressure is 20 bar we recharged to 90 bar with niterogen and still also the pressure doesn't exceed 40 bar . We checked also the y valve solnoide coil it was ok we checked the check valves on the control block also we checked the manual control solnoide valve for the change over cylinder of the s tube .we replaced the accumulator pump with repaired one but still has the same problem but today maybe we will replace it with new one so we will be sure if the problem from the Hydr pump or not.

 The machine number of the pump is 210102961

if the new hyd. pump does not solve the problem, you may have a problem with the accumulator manifold itself or any safety/pressure cartridges at the manifold, I have seen it before, that a manifold was cracked internally, and you lost pressure without any obvious signs. what to look for is a hot hydraulic hose from the manifold to the hydraulic tank. does your pressure increase with higher rpm's?

Thanks all it is solved by new Hydr pump I think the one who repaired the first one did not repair it well
