Enclose is a file with the drawing of the mechanism for the scissors cockpit tables of the Tiara 4000 that I got from Tiara.

I have not figure-out yet how to raise them manually. I will try to work on it next time that I am aboard.

So far I have thought of two "theoretical" ways to raise them.

1) if the auger moves manually by rotating it through the round access hatches under them (perhaps by carefully using a monkey or pipe wrench without damaging the threads of the auger applied, as close as possible, to the end of the the hydraulic motor), then they could probably be raised slowly. That will only work if the hydraulic circuit have a by-pass valve loose enough that would allow for the H. fluid to be displaced while the hydraulic motor is being rotated by hand and the auger is not frozen solid in the threads of piece #9 (in the drawing). 

2) if #1 fails, then the other way could be to try to get to the screws that hold down the fixed end of the scissor mechanism, ( the couple of brackets numbered 17 in the lower right hand side of the drawing ) and once those brackets are loose, then carefully pulling the tables up from the top with some lever applied to the sides or some other type of hook that could be slipped under the folded table ( maybe by pulling up with a thin U shaped wire slide from the side of the tables),until they are high enough to get  under the table top and unscrew the tops and be able to work on the mechanism from there. 

Please let me know how it went if you to do it before me.

My garage worked for a while as well as the engine cockpit hatch, but not they all are failing to operate.  My tables were not functional when I bought her.

It looks like I may to replace the pump and the directional valves.  

Does anyone have the part numbers and manufacturers for the hydraulic pump?    
 
The directional valves are Continental Hydraulic part number VS5M-3A-GB-75L-K-Y6032, which looks to be replaced by VSD03M-3A-GB-75L-C

Any information on the hydraulic pump is appreciated.


Thanks,

Steve

My 2000 Tiara 40 came with a Monarch Hydraulic Pump. 
I am enclosing a pic of the label with the model number in case it would be usefull.
Best.
