JD 5105 3 point wont lift

[Leejohn]

Tx Jim you are so right, that would be the very 1st thing to do.

I知 looking for something to test that out with now. Asked a few friends that have tractors and it looks like I値l have to make or buy one.

If this test is the preverbal fork in the road what will it tell me?

If I have pressure at disconnects what does that tell me and where do I go next?

If I dont have pressure at the disconnects what does that tell me and where do I go next?

Thanks again

if you can get hyd pressure(2800 psi) at scv breakaway coupler then that proves hyd pump & associated relief valve are operating correctly & the "no lift on 3 pt" problem is confined to 3 pt rockshaft piston &/or associated control valve components. If no pressure one needs to check operation of hyd system primary relief valve before suspecting hyd pump.
