gafarm49 Posted July 19, 2019 Share Posted July 19, 2019 Got on it today and it moved about 30 feet and I heard a slight soft thunk underneath me and it rolled to a stop. It shifts through gears and ranges and will slightly try to move when I shift it . Any ideas or where to check. I was busy but gonna check it out in the morning.

Good luck Link to comment Share on other sites More sharing options...

stronger800 Posted July 20, 2019 Share Posted July 20, 2019 Pull the two bolt inspection cover off bottom of clutch housing and look up in there with a flashlight quick. Does it "feel" like it still has clutch? Or can you move the shift levers and get the same feel with the pedal up same as down? Link to comment Share on other sites More sharing options...

You looking at it in the morning is probably going to get you a lot farther than a bunch of guys guessing. Only so many things could make it up and stop like that, none of which are "easy" fixes. You up for splitting a 986? Link to comment Share on other sites More sharing options...

Yep. But unless you are there looking at it, it's just a guess. I can guess with the best of them. Seen a lot in my career. But it is always best to look something over and make an assessment than it is to first run to the internet and ask people to guess. If he literally has no idea where to start, that's one thing. But it seems like he just hasn't taken the time to look yet. Either way, if it stopped moving, but has steering and hydraulics it's going to need split. If the OP isn't willing or able to split it, (which is why i asked) then the best advice to give is to call a shop. I'm not trying to be a jerk here, but we need to know if he's willing and able to split it before going any further. Link to comment Share on other sites More sharing options...
snoshoe Posted July 20, 2019 Share Posted July 20, 2019 My answer was not a wild guess. While it is not 100 percent certain. Unusual things happen all the time. The first thing is to remember is it is a 986. That signifies that it has a hydraulic clutch booster and the weakest diff in that frame. He says it trys to move when shifting. No syncros so he is using clutch. Clutch is apparently working. Hydraulics are working or he would have noticed the booster not working. Unless he can get it to move by standing on one brake or the other I stand by my answer. Link to comment Share on other sites More sharing options...

But the guy still needs to look at it. Still could have torn the facing off the clutch, or the center out of it. It would act the same way.

Wi Ih Posted July 20, 2019 Share Posted July 20, 2019 What wrong with going to the internet, I’ve been fixing cars since 1984 and there a lot of info out there and a lot of times it saves a lot of diagnosis time!, and if he can’t fix it himself he can get idea of what it is so he don’t get screwed by some mech Link to comment Share on other sites More sharing options...
Charlieu Posted July 20, 2019 Share Posted July 20, 2019 A number of years ago I had a customer that was madder than H****. I had just finished replacing the water pump on his CASE tractor and was driving it home to have it stop moving on the road. The square key that locks the rear axle to the rear wheel casting had fallen out and the tractor stopped moving. Real obvious if you knew where to look. Don't overlook the simple and obvious things.

If he gets an idea of what all it could be or what is most likely the issue he can determine if it's something that he wants to do his self or send out. I called the dealer when the 7140 lost everything because the TMR mixer blew a gear box and transferred the shock load to stop the tractor. After talking to them we determined we would tackle it ourselves. It ended up being the shaft coming out of the back of the front transmission had sheared off . We've never done a job that big before but we tackled it without any issues. I definitely wanted advise before starting to work on it Link to comment Share on other sites More sharing options...
pirlbeck Posted July 21, 2019 Share Posted July 21, 2019 If the tractor is equipped with differential lock you could try engaging it and see if it moves then. Link to comment Share on other sites More sharing options...
ole 815 Posted July 21, 2019 Share Posted July 21, 2019 Does it have clamp style wheels. Seen an axle strip out the wheel casting. Tractor wouldnt move. It sat, and axle spun inside the wheel. Differential sent power out to that axle. Didnt make a noise while axle was spinning ...... So like mentioned. Try diff loc and/ or brake pedals to see if it will move. Simple stuff first Link to comment Share on other sites More sharing options...
gafarm49 Posted July 21, 2019 Author Share Posted July 21, 2019 Well, its not the wheels. It will not move with the diff lock engaged. Pto will not turn. We will break her into. I will take the plate off and look into clutch area but I have bigger fish to fry. Colonoscopy prep begins in 3 hours Link to comment Share on other sites More sharing options...
Jacka Posted July 21, 2019 Share Posted July 21, 2019 Good luck on prep,had my first after years of being nagged by my Dr. Was not a bad deal,that prep.is worst though.I am a big baby when it comes to that stuff. But all was well in the end. HaHa no pun intended. Link to comment Share on other sites More sharing options...

PTO not turning may be stripped splines of pto gear and low side of TA must be bad or it would still move with no hydraulics. Link to comment Share on other sites More sharing options...

Some body watch diff spin while letting out clutch in gear. PTO isn't spinning so that would rule out the diff. My gut says it's in the IPTO shaft and gear area. When the splines go on that shaft it does what you are describing. That trying to move sounds like the splines on the shaft jumping. Link to comment Share on other sites More sharing options...
Matt Kirsch Posted July 21, 2019 Share Posted July 21, 2019 The ipto gear may have been catching well enough to power steering and brakes but any more strain than that and it slips... Agree about the TA. If the sprague was any good it still should move as if it is in low TA. No hydraulic pressure necessary. Link to comment Share on other sites More sharing options...
