Ih 454 hydraulics

[REStracTORATION]

Well its a 475 but all the same
Been stood for 4 yrs inside was all working ok when parked up
Anyway i got called to go and start it up so went the battery had charge in it and it fired up as if had been running last week which i amazed at didnt even have to jump/boost it.
So fires up and hydraulics go staight up onto constant pump, is there a valve that sticks on these i cant find my wsm for these and web search is not revealing much either.
If any of you would kindly show me some pointers
Thankyou

i know very little about this model hyd, but if the draft lever is at the top it will do as above, other thing is look at the back next to the top link linkage, the silver sensing pin should be out against the top link bracket when lever is up and go in when lever is down, if this pin is stuck it can go to constant pumping

Thats great thankyou i will check that when im there next sounds feasible that pin siezed slightly with standing.

The main draft control spools were prone to sticking sometimes if it's not just external linkage.

Could you have knocked the spool lever with your foot? Some were detented.
