Default Thar CRDe clutch problem

My 2013 Thar CRDe has a clutch problem. I don’t know what it is. I need some expert help. Here is the story. A year and a half ago I was going up a very steep winding road here. A proverbial “short cut” I had negotiated many times before. It is so steep the Thar has to do it in first gear with plenty of throttle. It is also narrow and curvy with a sharp deep concrete ditch on the left side and a 400-600 foot cliff on the other side. It is oneway, up, the way I was legally going. I get near the top and around a corner comes a large tipper the wrong way, downhill. Right behind me coming up fast are 3 delivery trucks and 3 taxis, no chance to stop and back down that way. The tipper’s spotter gets out and signals me forward and to the left. The tipper, of course, cannot back up this hill out of the way. He is way too heavy for that. I have to burn the clutch just to get started again, forward up the steep hill. My hand brake is of no use (thank you, Mahindra, for that). With my left side tyres actually a little over the ditch lip and my right side 1 inch from the tipper, I inch forward, at high revs, burning my clutch on the steep hill in order to move very slowly forward and up. No other choice. I made it after about a minute of this. The burnt rubber smell of my clutch is now in my nostrils as I get passed him.

But then my clutch pedal feels funny. It is hard to depress. The Thar still shifts, the clutch still engages/disengages but the Clutch pedal is hard to operate. I take it in to the dealer who installs a whole new “clutch pack” that includes, clutch plate, pressure plate, diaphragm springs and some lesser parts. There seemed to be a slight improvement but then any time I drove a little agressively, especially if I downshifted, the clutch pedal would immediately get hard to depress. A couple weeks back I replaced the same clutch parts again, including diaphragm springs, at the suggestion of the dealer. You guessed it, the clutch is still hard to depress and gets harder to depress if you drive aggressively and downshift a bit (I rarely downshift and never at high revs.) The clutch never falls to the floor nor does it fail to return upon clutch release. There is also now, a little chudder/shudder as you engage the clutch on starting up in first gear. Its impossible to start up without this chudder/shudder unless you give no throttle at all and just let out the clutch. My Invader has the same clutch and tranny and it shifts as smooth as a baby’s bottom and always has. I am relatively easy on clutches historically, losing one only of my many past clutches, mostly to age of the vehicle.

I am going in to the dealer this week. Do you guys have an inkling what is wrong with this thing so that I can give these tech guys a clue what to look for?

Just the two symptoms, clutch pedal hard to depress, and a little chudder/shudder starting in 1st from a stop.

Sir

The pressure plate bolted to the flywheel exerts constant force, by means of a diaphragm spring, on the driven plate, you need to check that first whether the assembly is okay.

The series of coil springs at the back of the pressure plate was better than the diaphragm spring and hence there wasn't any issue earlier.

The driven (or friction) plate runs on a splined input shaft, through which the power is transmitted to the gearbox.

The plate has friction linings, similar to brake linings, on both its faces, which needs to be checked and verified for smooth clutch engage.

For the clutch disengaged (pedal depressed)position, a thorough check of the arm needs to be done to assess the push of the release bearing against the centre of the diaphragm spring which again releases the clamping pressure.

This last bit may be where the trouble is...maybe. Diaphragm, clutch plate, pressure plate has been replaced twice.

Hello all
I have a Dec,2010 i20 which has clocked 23000 Kms. It's not used much, only about once every 20 days or so as I'm away and parents don't use it.
Today I had to travel to a place about 80kms away and so I took it out. Everything was fine till about 35kms on the highway except the clutch felt a bit harder than the usual.
As I entered the city, I had to stop at a red light. When the signal went green, I engaged the first gear but the car refused to move. I realised there was something wrong with the clutch and the gear wasn't engaging.
Somehow I managed to push the car to the side with horns blazing behind me. Called up the Hyundai roadside assistance, they connected me to the nearby service centre. They asked me to get the car to their centre myself as they did not have any people and won't be able to tow it.

This took about 30 mins, hopeful I tried starting the car and the clutch was working now. Taking a gamble I drove the car back to my place with minimal gear changes as possible. Tomorrow I'll take the car to the local Hyundai ASS.
Can anyone please shed some light on the issue.
Thanks.

My Accent (2009 - Executive) might need Clutch Overhauling, at 45k!!

Symptoms -
  1. Slippage test : Car is stalling towards the end of Clutch pedal depress
  2. Shuddering while releasing clutch in 1st and 2nd gear
  3. Loss of power (Mostly torque delivery, I could not feel the top end deteriorate)
  4. Chirping noise while engaging and disengaging clutch (This happens only for longer drives in the city - Stop & Go traffic)
  5. Stalls quite often.

I never ride on the clutch and always follow the best practices, Not sure why the clutch went kaput so early. What do you guys feel? Anything else might be the issue here?

Looks like the O/H would set me back by 6 Grands (approx.)

Also, there is a Free Car Care Clinic organized by Hyundai (24th Oct - 2nd Nov, 2015). Hyundai owners could get a check-up done.

Hi,

I am driving Fiat Grande Punto 2008 1.4 8v 77ps in Germany.
It is an used car and I bought it last month. It was already driven for 1,44,000 kms.

I used to experience clutch judder every morning when I start from 1st gear and after few mins when the engine becomes warm there will be no clutch juddering.

Today when I was driving in city, my car refused to climp up in a slope (not too steep) and stalled several times. Finally I managed to climb up using park brake.

But after this incident I felt slight vibration when driving normally. Also even in small slope, I have to give more gas than normal to pull off from stop (e.g. From red signal) and there is noticeable vibration in the clutch pedal during clutch pedal release.

I tried to test the clucth using park brake. I pulled the park brake, engaged 2nd gear released clutch pedal: engine switched off after a little vibration at the end of clutch pedal release.

Guys please give your opinion and suggest me any other test method to check whether clutch is burned off.

Thanks in advance.

Update:
Today morning I went to workshop to check the clutch. The mechanic did the test and told clutch is working fine.

He engaged park brake, engaged 1st gear and released clutch slowly without giving gas. The car moved and engine did not stall. He then repeated the test with reverse gear and again car did not stall. He told if the clutch is kaput then engine would have stalled. But I read the opposite in this thread somewhere that engine should stall if the clutch is in good condition. I tried the same test yesterday with 2nd gear and 3rd gear. In 2nd gear engine stalls after some 70% pedal release and in 3rd gear engine stalls immediately after pedal release.

I drove the car yesterday night and today morning. There is no vibration at all and the clutch was operating as usual. Regarding deviation in engine rpm, usually it will be 2000 RPM@70 kmph (5th gear) but now I notice it to be between 2100-2200 RPM. I am not sure about this RPM deviation because I am driving this car only for past 20 days and I do not know the exact RPM-speed ratio.

I am confused still whether clutch is working fine or should I check with other workshop to get 2nd opinion.

Hi all,

I drive a 2012 WagonR VXi which is at 30600 kms and since the last couple of days, the engaing of the 1st gear has become very difficult. I drive in bumper to bumper traffic on western express highway in Mumbai. Works butter smooth for abut first 10 kilometers, then the 1st gear engage becomes tough, i need to put extra pressure on the clutch to get it to 1st gear. Can anybody please help me with this ?

Do i need to get the clutch replaced. On my last 30000 service the SA said the pressure plates might give away. Requesting help from the experts and knowledgeable members.

Regards

Seems more likely to be a problem with worn out synchronizing rings. Try slotting to 1st at standstill from neutral. If it goes smoothly, and the only issue occurs when downshifting from a higher gear to 1st while the car is in motion, then your problem is likely to be worn out synchronizing rings.

At 30600 kms, its highly unlikely that the clutch plate would go, unless you're riding on the clutch.

Default re: About clutch wear & replacement

Symptoms:

1. Mileage drop
2. Heaviness in clutch pedal play
3. Gear slotting esp to 1st from neutral (and vice versa) and from 2nd to first is heavy. As in, gears are not engaging easily (need quite a bit of efforts, though 3rd gear onwards, shifting is still OK)
4. noticeable decrease in pick up and general slight loss of power as compared to what it was earlier

Is this a case of clutch assembly (or parts therein) needing a change?
