If memory serves, the gaskets where .015".  If it was much thicker than that, you could have changed the distance between the pump piston outputs and the transfer block enough to allow the fluid to escape back into the pump housing.  

 

I've never had my poppets out, so I have no idea how many shims are in it.  Did you follow the assembly note that says "Be sure open ends of guide point outward."  

 

Not sure you should be able to feel the individual hydro motor pistons when you spin the wheel, but as long as there is more friction when you are in drive, the transmission should be working.

 

Here is what one of my manuals suggests for trouble shooting the T66X:

 

PROBLEM/FAILURE                                                     PROBABLE CAUSE

 

 

1. No output torque forward and reverse                 1A. Low on oil

                                                                           1B. Tow valve in up position

                                                                           1C. Input shaft key sheared/ missing

                                                                           1D. Linkage off or broken

                                                                           1E. Soft ride valve stuck

                                                                           1F. Internal wear/damage

 

2. Momentary lack of output then power surge         2A. Soft ride valve stuck

 

3. Initial output OK but loses torque after running     3A. High pressure relief valve spring getting weak

                                                                            3B. Refer to 1 A

                                                                            3C. Oil temperature high due to overload or ineffectual cooling

                                                                            3D. Water in oil

                                                                            3E. Internal wear/damage

 

4. Output power less than original                           4A. Linkage out of adjustment

                                                                            4B. Refer to 1 F

                                                                            4C. Loss of engine power

Thanks for the info. Today i disassemly the transferblock, and replaced the o-rings. Im despetate right now, so i am trying everything to see if it helps. The gaskets could maybee be the problem, the gaskets i made were .024" I will try make som gaskets that are only .015". Hope this will help. And thanks for the help so far.

Have you got the Vickers running again yet?  If so, what was the problem?
