Agracat 3720 steering pump problems

[hazer36]

Need some info on power steering pump,mainly which way flows go,bought tractor with no hyd at all,trying to get ps fixed then will work on loader/hitch
Removed ps pump ,someone had been inside of it,could till by the way it was put together,was worse looking pump on inside I have seen,looked like something was run through it.
Does it pull from tank in front of rad?
Also does pto have to spin for rear pump to work?
Thanks

Depending on engine but if you have a tank by the radiator that tank is for steering only, the rear pump is for the hydraulics loader and 3-point.We have all the replacement parts, you need to make sure and have tractor model and engine model, give us a call 979-865-4002
We have manuals but they do not include pump breakdowns and we don't have them either.Your tractor will be the same as the Jinma 354

Ok guys this is driving me crazy.I must have put this together 20 times.
The way I believe it goes one through the body bolt doesn't line up or won't start.Also pump won't turn,and hyd lines doesn't line up well.
I think the pump body with the 4 bolt holes is the suction side,so the big slot inside of backside pump should go towards the back or high pressure side.
The pump is on right side of engine and mount spins clockwise when looking at it from seat,so drive gear of pump would be on top slot of pump.Also the opening of the e shaped o rings should face the low or suc side.don't want to put it on wrong and blow front seal out.
Any thoughts or comments will be appreciated.
Have already got loader/3ph pump working and loader valve rebuilt.one question about it,does it have a front seal on loader pump ,wasn't one on it when I tore it down.

Thanks Tommy,it helped some,also found others on you tube.
And you do need a seal on loader pump,I hate it when people mess with tractors that shouldn't be near them.previous owner had been in both of them,had aluminum blocks turned wrong way.
Also this tractor is kinda rare,it has the 4 cyl,480 I believe.runs very smooth.
