1070 8 speed Not Happy

Determined

Well-known Member
Was working the 1070 yesterday, not hard just busting up turds in the hayfield with 50 foot harrows.
Halfway up a steep hill it said not going to happen.
Shifted down a few gears and kept going.
Stopped and checked clutch linkage and it was fine.

So it needs a new clutch, could be worse, will tear into it once I get caught up around here.

Any tips, tricks or things to look for or look out for?
 
(quoted from post at 20:14:26 05/15/18) So, I'm not clear on the problem. Were you running out of power? Was the clutch actually slipping?


No shortage of power but you could definitely feel the tractor quickly slow almost to the point of loosing forward motion at which time I hit the clutch and brake then grabbed a lower gear and finished climbing the hill.

What was really strange was yesterday I fired it up in the morning and had no steering the gauge on the dash was showing no pressure and I had nothing at the remotes.

Hard for me to see the fluid level in the sight glasses in the bright sun so I added a few gallons of oil to it, no change.

At this point I figured I would just try to get it back closer to the yard so I could unhook it and grab another tractor.

Cranking hard on the wheel I could get it to turn a little so I started a big turn to get back to the yard.
6th gear at 1500 RPM and a big hill between me and the yard I climbed the hill without any slipping, as I crested the hill suddenly my hydraulics came back to life.

Figured I would see how far I could push it and ended up finishing off another 100 acres with no further problems.

Will see what it does today and try it up the hill that first gave it grief.

Just a thought I pressure washed all the winter feeding crud off the tractor in the morning before I went to the field is there any chance when I washed it some oil managed to get moved/splashed on the clutch?
Maybe it got burnt off when it was slipping on the hill.

Just not making a lot of sense to me, clutches typically do not heal themselves, my wheels were not spinning on the hill, RPM's stayed up and forward motion was almost done when I downshifted nothing else to blame that I can think of other than the clutch.
 
Disconnect the linkage from the clutch arm on the side of the bellhousing and see if the arm moves freely. I had one last year that the bushings that the throwout bearing shaft rode on got tight and had similar symptoms to yours.

I split it before I realized what was going on.

A little heat on the shaft and some Oil and I think I could have prevented the split.
 
I'm with Rich on this one. The needle bearings on the clutch fork shaft are dry and working like sprags,and not allowing the shaft to rotate freely.
 
Finally had some time to have another look at the 1070 this morning.

Unhooked the linkage going to the clutch, shot some oil around the shaft then took a hammer and tapped the arm up and down, in and out etc.

When that was done I went to re-hook the linkage and I had gained enough travel in the good direction that it took 2 1/2 turns on the adjuster to reinstall it with everything at rest.

Tried it close to home first and it was feeling good, drove it down to the hill that caused the grief in the first place and it walked up it like it wasn't there, spun around and climbed the hill again this time in 7th gear with reduced throttle, it lugged down and started blowing black out the pipe just the way it should with no detectable slippage.

As far as the oil level goes yes it was still down a couple of gallons, topped that up and all is well.

A big thanks to everyone for there advise, without you I would have pulled it apart for nothing.

If there was a way to E-mail cold beer there would be a few on the way to you already.
