minniapolis moline jet star 3 hydraulic problem

01gentdc · Feb 23, 2016

Friend of mine just got his Jetstar 3 m m running after setting some 4 yrs , he says the hydraulics worked fine when it quit . but not now . I think the hydraulic pump has a poppit valve or sumthin stuk,,no hydraulics., and the steering is all over the place,. it is guidable in low gear in order to move ,, but really bad ,,. it seems that the rear pump provides life to everything ,,. steering , remotes and 3 pt, there are 2 levers under the seat that have no resistance,,. I assume one is a shut off and the other mite be draft control , does anyone have any pointers they could share with us , we sure could use a book on this tractor for sure , if weknew what it was . the tag is nearly impossible to read,.. it has a decal that says 4 star super, but it looks, like a jet star 3 . the Moline guys are a bit scarce on advice,.

Doesn't matter which. Did you check Hyd oil. Hyd is separate. Just holds about 2 gallons. 2 levers under seat. Are rate of drop. And draft control response. Make sure all 3 Hyd levers are centered.

You could post a picture we can identify it. Next there is a pop it in the pump, mine stuck and did what your describing. It is in the top pointed toward driver side. Also mine the filter can be touch after changing it.

I agree, post a picture if you can. You can also post this on the MM forum as well.
