5011 clutch is slack

[smelly]

ok guys been awhile, but now I have a new problem. I was slowly backing up when suddenly the clutch disenaged, and I was in neutral. I can shift to all the gears easly enough, and can move from high to low too. but after releashing the clutch there is no forward or reverse movement.
the clutch pedal no longer comes all the way up to its highest point, it is like almost 2 inches too low, I can raise it by hand easly enough to the highest point but it just drops down when I let it go. and when pushing down on it ,it seems a bit harder.
So anybody got any ideas of what it could be.
tomorrow moring I will remove the cover under the dash board to see what is behind the clutch pedal . will need some coaching to know what to look for. I imagine I will have to check if there is enough oil in the cylinder , but at this time of writing, err typing I have no idea of what to expect since everything is behind the cover.
Any feed back will be greatly appreciated
???

Hi

Your clutch is mechanical, so no fluid to check. take the side plate off the clutch housing to have a look. I dont think you'll see much as I suspect the rivets have sheared on the centre of the clutch plate. Can you move the gear lever and select gears without the clutch down? If you can, then you have no drive out of the clutch and the tractor will have to be split.

Those model have spring inside clutch housing (for return clutch pedal). It can be damaged. If it is so, you dont have to share tractor, you can fit standard spring outside clutch housing

please explain more details, can I see that spring from the ouside of the tracto,r via the square hole on the side of the tractor housing? as before mentioned I can shift to all the gears, including high and low the gears engage fine, bur when I release the clutch nothing happens, the clutch pedal doesnt come all the way back up there is at least 6 to 7 cm that I can lift the pedal with my hand.

ok ... when the clutch is pressed down I can switch to all the gears including high low gear selector. but with the engine running if I try to push the gear stick to a gear , without pressing down on the clutch, the gears grind....

Hi

Ignoring the clutch pedal for a minute. I'm just wondering if has broken a half shaft or sheared the rivets holding the crown wheel to the diff housing. Try moving the tractor with the diff lock engaged.

The thing that puzzles me, is the fact that the problem first occurred when the tractor was IN MOTION (which leads to believe there is a transmission problem) but what you describe of the clutch pedal, is weird too...

I just had a brain fart:[/] Start looking at the high/low selector lever: There is a chance that the C pin holding the lever to the little shaft, has broken, and the stump of it causes enough friction on the shaft, to lead you to believe that you're actually shifting it...
Had that once on our 5245... The stump had enough friction to put me into neutral, but just scratched over the shaft when trying to select high or low...

Do you hear gear noise when shifting the high/low lever without depressing the clutch, or does it only grind gears when shifting the main 5 speed without clutch ???



But anyways, If that doesnt work, put the tractor IN GEAR, jack up one wheel, have your mate turn the wheel around and look into the clutch inspection housing if the main shaft is turning... If its not, your problem is in the transmission. If it is, its a clutch problem (probably a broken torsional damper spring jammed somewhere inbetween).

AND !! what about the PTO ? does it work ? PTO clutch works ? 3pt lift goes up and down ?

hi ya Renze.... well today I put the tractor in 2nd gear, and then started the engine, the engine purred like a lion and I did not jump forward. the pto is functional the 3 point hoist works fine.
with the engine running ,I press on the clutch, all the gears engage with out noise , the high /low also. If I try to engage a gear with out pressing the clutch I get grinding ( normal )
the poblem seems to be more of a transmission problem. tomorrow with the help of a mate, will will jack up one side as you sujested. will let you know.
Question: do I have to remove the cabin to acess the transmissim and I imagine to see the gears and such, do I need to remove the hoist control....also?
I think I am getting in over my head here....


thank you all for taking the time to respond to this post.

Just to add to what Renze has said, you may not be able to see the shaft in the clutch as it is the centre shaft and has another shaft round it blocking your view.
You can see the transmission by removing the cab floor and gearbox cover. You can get at the diff assy by removing the hyd top cover.

ok new info, for our internet mechanics......
the left side rear wheel had most of the 12 bolts holding it on slack by a good 1.5 cm,at the bottm less so at the top. so much so that one bolt broke . So now the the tractor will move if I press on the diferential lock, and hold it down, then we can go forward or reverse. so what do you supose is broken in that rear side axle? and how do I remove the axle, for that side, is there somthing special I should know , or does the axle just pull out?or do I have to go through the floor to the main housing gears?

ok problem resolved.... the half shaft is broken.....because the bolts from the hub slaskened thee was too much presure on the axle and it sheared just after the splines.

 

[Renze]

Anyways, you can just pull the halfshaft off with an engine hoist, a forklift or anything else that can lift about 250 kg from under the mudguard.

Just slacken the hand brake bolt on top of the rear axle, then you can pull it off. Make sure you drain the transmission to at least 5cm below the halfshaft center.

You might want to see if the brake shoes still move freely once you get in there...

yep , thanks
we got the job done.. another trick is to disconnect the differential lock shifter mecanism , that way the lock gear is just tight enough to stay put, aligned with the differntial , when you slide in the new shaft with the portal, into postion.other wise its falling all over the place.I used the broken half of the shaft with the spline to align the gears up.
