Renault Celtis 426

[Gabriel]

Hello everyone, recently I bought a tractor Renault Celtis 426 ( second-hand ) and I just ran into a problem. It seems like the tractor struggles when I am trying to put the tractor in 1st gear. My dad which is using it said that the problem could be the clutch. Anyway I have a photo (attached to this topic) with the dashboard lights when I am trying to put tractor in 1st gear, could someone please tell me the meaning of those lights which are ON so I will figure out what the next steps should be, thank you for your time.

One is hydraulic filter
One is electrical fault with transmission

Now Then..
Hydraulic filter,,,, or low transmission oil pressure??
I used to drive a Ceres 95 that used to flash a similar light when using the splitter..

The red triangles at the bottom are the hand brake.
Orange light is transmission, both electrical and oil pressure I think.

Try it with the splitter in low (tortoise), see if you have the same problem.

Is it the RX or RC model? If its the RX, do you still get the problem if you use the clutch on the gear lever rather than the foot clutch?

Thanks for fast reply. I had a phone call with my father and he already ordered oil and filters, also he told me that this model is Rx and the problem is serious then I thought, he said that it only works for 1st gear in low(tortoise) and for the rest of the gears the tractor just won't move ( he can put the lever in those gears). Also he said that there is no smell of clutch( when the clutch is damaged there is a specific smell when you try to use it)

The forward/reverse clutch slip sealing rings will have failed or the plates burnt out quite a common fault. Can be split at bell housing and clutch unit pulled out the front

 

[Gabriel]

The interesting part is that tractor runs in reverse just fine and also when the oil is cold tractor goes fine in reverse/forward, the problems with going forwards appear only when oil is warm

Someone having any ideeas what could be the cause of the problem? Thanks.

This is the closest thing you'll get as an answer / solution. There comes a time when you have to get your spanners out,,,, or take it to someone with spanners.
If you're waiting for someone to tell you it's a 5 minute job,,,, it's not going to happen.
I'm not familiar with the the thing and can't find a parts diagram.. There is probably a forward and a reverse clutch. The forward one is faulty therefore no forward drive. The reverse must be working OK.....
Right,,,,, spanner time.......

Well yea of course I am taking actions in the mean time but just wanted to see what others may thought about that, also as I said in a different post here the forward clutch is also working when the oil is cold

Had something similar, where the splitter didn't work, only works in tortoise. That requires splitting the tractor as clutch pack gone.

Also the switch on clutch pedal gave trouble and had to be replaced, only happened when the oil was hot, but was just coincidental. Reseaonably hard for an idiot when it comes to machinery weather the problem was mechanical or electrical. also forward reverse shuttle temperamental and needs replacing.

The fact the tractor works in reverse suggest that the problem may be electrical problem with shuttle lever?

Just reread that and Meant to say "idiot like me" . Wasn't implying anything about the OP. ?

 

[Tractortech]

When the oil is cold it's more viscous so less likely to leak, when warm, leaks become more obvious..
Cold oil,, less leakage = clutch works..
Warm oil,, more leakage = clutch slip.

Just reread my previous post and meant to say "idiot like me" . Wasn't implying anything about the OP. ?. Just trying to say it wasn't that straight forward for me to diagnose problem.

It's no good guessing I'm afraid. Time to put some pressure gauges on it . Take readings with it in forwards and reverse also with the splitter in high or low and 4wd in and out. We had a celtis that had burnt out the forward clutch but our pressure drop was in the 4wd pack. Only found this out by test driving and operating all the functions. In 2wd you could push the tractor gently forwards which would make the pressures fluctuate .

Thank you very much for help, I may come with an update after I know what it's the cause of the problem

Hi, did u ever get to the bottom of it. I've got what sounds like the same problem on a 456, but is puzzling as had clutch refine only 1200 hours ago

 

[Gabriel]

Not yet as we bought another one to continue work in the meantime but we are pretty sure that my Celtis have some clutch/gearbox issues so in both situations have to be split.

 

[Classyhay]

Thanks. I reckon it's the same issue, I'm going to split mine so I'll let you know if I get to the bottom of it.

 

[Gabriel]

Ok, thank you.

Mine was the forward clutch pack slip rings on the input housing at the far back of the revershift clutch packs. Two poxy bits of plastic! About 12 quid each from claas but a lot of work to strip her down, pull apart and pull the clutch packs out. As someone said above, a common fault apparently - not very handy given the work in replacing them. Shame because she's a very good tractor otherwise.
