Hydraulic o rings

[Dexydog64]

Hi. Has anybody got either a picture or diagram that shows the layout, positioning for the o rings associated with the strip down and rebuild of the hydraulic top box on my dexta. On removing the top box from the tractor to replace the worn pin that rides on the cast quadrant, some of the o rings fell off. I have now got the replacement o rings and have replaced the worn pin, but I am note sure where the o rings should go.

I think that there may be a drawing showing the location of the "O" rings in the workshop manual.

However if you look closesly at the mating surfaces of the various components you will see that some of the holes are counterbored to accept an "O" ring!
