I have a 1964 Super Dexta, that ended up with a frozen quadrant lever last year. (Slight upward pressure would cause it to lift but lever was stuck) Opened it up released where the quadrant lever had sort of rusted with the other bits. Checked all and lubricated, all valves seemed to slide well, cleaned and rebuilt the Qualicontrol and the rear spring which also was seized.Changed oil as was becoming emulsion and cleaned filter and replaced o rings. New gaskets, sealed leaky bolt holes to try and reduce water getting in there.
All back together, Quadrant lever moves, but now hydraulics will only lift 2 inches. Hid it away in big shed for 3/12’s, but now need it. Where have I gone wrong?? Any help please! Watched loads of YouTube but no real help!! Very despondent!!!
Did you make sure the adjustments are correct? Does this only happen with the selector lever in one position or both? I suspect you'll need to lift the top cover again, worth looking at the manual and Brian's guide on this. Need to know exactly what it does to what lever movement to be sure about what's happening.

Hi
I have been away, and went to check over hydraulics, oil filled to right level, may need to loosen main control spring a tad.
It doesn't matter where the selector lever is either. The lift arms appear to be partly raised and movement of the quadrant lever causes a small lift 1-2 inches. I have been trying to find Brians guide on this and have the manual but my cognition from an old brain injury is poor. Any pointers would be great please!! Thanks
Hi
Thanks for all the suggestions , but I think I could do with some help on this. I live South Shropshire 15 minutes from Tenbury Wells. Has anybody got recommendations for a mechanic who could service the Hydraulics of my 1964 Super Dexta? I have the top off, but could do with some help please!!! I will pay, as long as it’s not too silly!!!
