3-Point Hitch hydraulic problems on 2030

[Tx Jim]

Pto is operated off of trans pump psi while loader is operated off of main high pressure ft pump. Loader valve if the convertible type(open to closed/vice-verse) could have a blown internal(replaceable) o-ring(parts key #10). Technically the o-ring mentioned above and spool seals is all that's repairable on a spool valve.

Check frt hyd pump coupler for stripping. How long since hyd filter was changed and sump screen checked/cleaned? Which type pto continuous running(dual stage foot clutch) or hyd ind pto??

 

[Paul arnold]

Hi thanks for reply the coupler is fine not sure when filter was changed not sure where it is and sump screen check not sure what this is? And the pto is controlled from a leaver just underneath the steering wheel on the right hand side next to the hand throttle.

Are you 100% sure that main hyd pump shaft is turning with the engine crankshaft?? The couplers have a history of spinning on the pump shaft.Sounds as if pto is the hyd ind type. Screen(parts key #30) is accessed on RH side by hyd filter

Any ideas where the hydraulic filter is on this tractor ??

Pump 100% turning with crankshaft checked oil filter spotless took the screen out was nice and clean apart from the last inch or so of the screen a fair bit of crap come out would this be enough to give me problems ? Thanks

Loader control valve could be leaking internally. Does loader have an independent hyd valve or is it controlled by tractor remote valves(SCV's)??

Which is the loader valve please? I cracked open the 3 hoses into the front hydraulic pump the top inlet had oil the discharge port had oil but the right inlet had nothing what so ever dose this info help?

It's been since the late 80's since I worked for a JD dealer but IIRC line #1 carries trans pump oil to frt hyd pump and line #13 carries high pressure oil to the rear. Ind loader valve would be attached to loader on RH side.
