1401 3 point drops

Postby dagnblond » Tue May 26, 2020 7:01 am

I've got a 1401D and when I was backdragging a driveway one of the lift pins on the 3 point sheared off dropping one corner of the box blade into the sand bringing me to a very abrupt stop. now after replacing both pins the 3 point will not stay up so I have to constantly lift it back up. any clues where to start/ I did raise it up and lock it and with engine off it stayed a lot longer but did seep down

Is the lift handle drifting down or staying at your set point? Are the lift arms parallel? Just wondering if the rock shaft might have got twisted when your pin sheared off.

I am not familiar with the 1401. Since dropping has started since the pin shearing it seems evident something had to be damaged at that time. If it does slowly leak down with stop valve closed then the piston o-ring is likely leaking a little. Any reason to think that slow leak down is worse than before the pin shear? If not then maybe the control valve is at fault. Any picture possible of your control valve area?

I would check it with the lock valve closed and also take a look at my feedback linkages.

do you guys think I need to rebuild the lift control or just replace seals on the lift arms

I am unsure what I am seeing. Did the right hand lift arm pull off the shaft a little or did it pull the whole shaft through the lift housing a little bit? Also unclear just what damage happened to you control linkage. I would not want to offer a lot of advice based on what I am understanding at this time.

can't really tell what exactly happened, both lift arms are flush with end of shaft. as soon as I get a chance I want to loosen the bolts and see if the lift arms will slide in a little or if there's any odd movement or bolt hole wobbled out or whatever. was just wondering about just replacing all O-rings.
if I lift the 3 point with no implement on it stays up but any weight it sinks

Is any of the lift control mechanism bent or distorted that you can tell?

"both lift arms are flush with end of shaft"

That being the case and yet a little slack on the one side of the lift housing would make it suspicious the rock shaft has been streched or broken.

Not to my knowledge. Maybe it won't end up being expensive. Although some work involved it is not a major job to remove the lift housing.

got a little time today but it's tough working out in 90 plus degrees
took arms off and there is a good bit of side to side movement but don't see any obvious damage but O rings are very different size from 1 side to the other don't know if 1 stretched that much or was wrong to start with. also if I remove the 4 bolts on the cover around the lock out will that just pull off or is there a bunch of stuff that will come with it ? I pulled the lock out but can't get the piston to come out to examine it
