Selector leak .

Pto shaft leak .

Just a wee update , got a decent amount of new oil reestablished. Once I got the air out I can make lift arms on rear linkages lift hydraulicly and lower under gravity I assume this is normal for this tractor . Can also get hyd pressure up to the front loader arms again to raise hydraicly and lower via gravity ( I assume it opens return line to tank and relies on the weight of the arms to do the rest. Now I am fighting a few leaks which is why the oil was low.got a new pto shaft seal coming as that's the biggest leak ,(now that I have it cleaned up a bit more I can see where the leaks are coming from. Another leak is coming from the control leaver area which controls the aux hyds. I will post a couple pics in case anyone is following along with my ramblings .

Thanks for this information very informative !

Looking for a bit of info , working blind here , hydraulic oils (what remained ) not in good condition, am I right in saying that the hyds are two separate systems ? Fill plug and drain plug at the rear look like they do lift arms and aux hyds? Fill plugs and drain in the middle seem to be more like PTO ,clutch,wet brakes ? Are the drains at the hubs all meant to be full of UTTO oil?or is the hub oil shared with transmission? Rear oils made me laugh looks like something out of starbucks (see photo)

Correct , Scotland! Still learning about these tractors like I said first time with one . Working on the hydraulics today .

I am in the UK , specifically north Scotland next to a place called Elgin . Although I think there's an Elgin in Canada too? .

Hello to everyone newbie here with first post . Got a McCormick international harvester 523 trying to bring back to life . Been engineering for 25+ years but first time with tractors . The tractor had blown head gasket when I got it but I am slowly going to work my way through all the issues ! Anyone got an operators pdf manual for this type of tractor ? It's got a German neuss D179 diesel 3 cylinder engine. Thanks in advance.!

Got the head off , coolant was in the sump! New valve stem seals and a gd clean and de coke . Relapped valves and reassembled. Flushed rad , checked thermostat Got head back on rebuilt and it fired up. Tractor lift arms won't move. Clutch seems off so going to check out the hydraulics next. Just ordered 20 litres of UTTO oil and new hydraulic filter.
