If Spare can't help here's what I did My volvo hyd cyl's were leaking, I took mine to a good local hyd shop. My shop does nothing but repair hyd rams. Mine had to pull mine apart measure what was there and look for them in a catalog book. Volvo doesn't make a replacement kit for mine. Hope this helps

not trying to insult any ones technical ability, but I always try to cover the basics first.
sit the unit upright and run it up if it will go(blue to positive, green to negative), if it doesn't, unscrew the fill cap(keep the unit upright) and add fluid( I use an oil squirt can with 10W30 in it), if it will take fluid, keep adding it till the ram starts moving, once its moving up, cap the reservoir and run it up as far as it will go, then run it down, you may have to add some pressure to get it to go down(keep the motor running in down direction, green positive, blue negative), if it keeps moving, stop on the upswing and add some more fluid, cap it and keep going. if it will not move in either direction, remove the motor/reservoir assembly(the f our gold colored bolts in the pic) and check to see if the shaft is twisted off, or the coupler is broken, while you have it off, check the screen in the pump for blockage, let me know if you find any extra parts inside the reservoir.

thanks guys, seems if i have to go cmc, they are a quality product.
cv, i actually looked at that one this weekend on ebay, but i am leary of a used one, like i say, i have 3 others doing the same thing. garage, i don't think it is in the ram, it moves free when removed from the block and goes up & down when air is applied. spare, i did most of above, except when i added fluid i used merc power trim fluid, which is quite a bit thinner than 10w30. do those units use a different fluid?

pull the motor off and check the coupler, if the shaft coupler is broken,then its an easy fix
