Things moving along slowly on the tractor these days, I have managed to get the paintwork on the bonnet tidied up and the repair blended in (in a fashion:laughing

I rubbing it down with P600 wet and dry. then P1200 then P3000, the paint took about 3 weeks to dry enough for me to get on it with the wet and dry, its turned ouy pretty good, for an old tractor and a meer amature like me. The red oxcide part is a weld repair on the cross beam, it was cracked and I never noticed until I went to reassemble the loader.
I also put on the decals, the cut of the angle is not quite correct, I might let the supplier know the correct angle for the next person which makes a purchase.

I had to replace the seals on the slewing rams as they were leaking, these were from the origional backhoe as the ones fitted to the replacement backhoe were pitted internally due to water sitting in them, I just wonder if the tank had water in it and the water made its way to these rams and never got out, we will never know.
I am also monitoring the rear jacks as there could be a weep from one of those too, thay are the origional loader rams, they were pitted externally so with them being out of sight its a good place for them hidden in the jack.
I had a bit of head scratching with the loader hydraulics, I now think I understand how the complete system works, as you can see the loader has 3 3/8th hoses, supply, return and what I think is power beyond (Not sure if thats what it is called but have read all about it), but basically what I think happens is the oil from the tractor is fed from a triangular block under the seat up into the under seat spool valves (steel pipe in the picture) it then passes through the spool block to the top left in the picture flexi hose which is the supply to the loader spools, the return from the loader spools is then fed back in to the rear of the triangular block completeing the loop, the 3rd hose from the loader spools with the large unpainted square block is fed back in to the rear of the under seat spools which ties into the last steel pipe on the spools which is to an open return to the rear transmission. I think what happends is the oil then flows with no back pressure until the hydraulic leavers are operated which in turn then diverts the oil through the return side of the loader spools.

I had some issues with the loader spools leaking, tonight I changed the 2 O-rings on the tilt side and am hoping thats cured the leak.
