The clutch plate can only be fitted one way. If you noticed one side of the plate has a raised section that contains springs. The other side is flat. Puting the plate the wrong way round allows the raised section to hit the heads of the flywheel bolts and this is causing the clutch to spin even though you have the foot on the clutch. Make sure you have properly bled the air from the clutch system. Mostly there is a notice printed on the clutch plate which reads like flywheel side or this side away from flywheel

SOURCE: Removal of slave clutch master cylinder

The hydraulic cylinder is in the bell housing. When you separate the motor and tranny, you will see it as a unit with the throw-out bearing. Take the hydraulic line off before you start. You will have to bleed it when you are done.

SOURCE: Clutch will not Engage

You need to bleed it out. It takes some time to do this. There is a bleeder valve above the hose fitting on the tranny. Have some one pump the clutch and hold it down and crack the bleeder nut. Just like you would when you do your brakes.

If it was selecting gears ok before the clutch was replaced then the slave cylinder should be ok, it may just need bleeding. If it was playing up before, you can get them rebuilt by a brake specialist or a wrecker would be a cheaper option. They are very easy to replace, hardest part is bleeding them which is what I suspect is wrong with yours.

Check all your hydraulic connections for seepage . If you find nothing leaking, check where the rod goes into the master cylinder under the dashboard...If still nothing, I'd change the master cyl, as it is likely internally bypassing and permitting the clutch to release. PS it takesa a special "touch" to shift gears without using the clutch, if you cannot do that don't drive it Till you get it fixed...you will damage synchros and will need to have trans removed and rebuilt. $$$you don't want to spend!!!

The Clutch disc and Release Bearing for the TD4-Freelander, were replaced recently. The Pressure Plate was still in a good condition.Gears difficult to engage.Please advise.Tks.John.


Most likely still has air in hydraulic clutch slave system. Many transmisions will have dificulty shifting if clutch doesn't full disengage. If air is in system it won't allow full disengage thus difficulty in shifting even possible grinding gears

Hi i just put a new master cylinder a month back now today my clutch felt hard and when i put it in reverse heard a broken sound clutch went flat and oil came from the master what can the problem be


Umm...

A mechanical 'breaking noise' doesn't sound good. It's hard to diagnose a problem online without being there to see/hear the vehicle. But .. it may be that your clutch pressure plate has broken/ release/throwout bearing has broken?

It's difficult to see why the master cylinder should leak - unless it was incorrectly fitted in the first place?

Just to check ... The master cylinder is in the engine bay/compartment and is where you top up with clutch fluid. When a master cylinder fails it usually results in no pressure at the clutch pedal, not a leak.

The clutch slave cylinder is the one that does all the work. When you press the pedal hydraulic pressure is sent from the master cylinder to the slave cylinder - which then pushes the release/throwout bearing against the clutch pressure plate and 'disconnects' the driven plate .. allowing you to change gear.

The slave cylinder is the one that does all the hard work - it is located somewhere where engine and gearbox mate together, usually at the bottom right/left. It's usually the one that fails/leaks. It's quite easy to replace..

I don't think it is anything to do with reverse gear. It's more to do with the clutch pedal being depressed - and, I would suspect - something has failed.

The link below is generic images of a clutch:
clutch diagram Google Search

Basically, a clutch is 3 parts. There's the 'pressure plate' which bolts onto your flywheel. The pressure plate is a 'spring'. You depress the clutch pedal and the release/throwout bearing presses onto the centre of the pressure plate causing the 'fingers' - the springs - to bend back and take pressure off the driven plate - which is the link - the drive - between engine and gearbox.

If you have a leak your clutch will not work. This causes a 'grinding/crashing' noise when you try to change gear. The first thing you should do is check where the leak is coming from and do something about it.

The 'noise' that you mention may be due to the fact that the gears are 'grinding' as they try to mesh together without the use of the clutch.

The first thing you should do is check why there's a leak. It's difficult to see why a new master cylinder is leaking unless it was incorrectly fitted and damaged (pipes incorrectly connected..).

If it's the slave cylinder that is leaking - replace it. Easy job.

If Master cylinder and slave cylinder are ok - you have to look at your clutch unit. A clutch is always replaced with 3 parts ... throwout bearing/pressure plate and driven disk.

2002 jeep wrangler recently had a new clutch put in,I am starting to have trouble putting it into 1st gear and shifting into 2nd, all other shifting fine.what could it be?


to answers 100% accurately id have to drive it.

but here in net bunny land, cant do that!
but can ask you to post full symptoms.

(trans or clutch issues)
question 1: can you start car in any gear. clutch held to floor, even reverse )
Q2: once started, can you always shift to reverse (the tricky one, gin?) and not grinding and no complaints,balking?
yes/no
yes then your transmission fluid is low.
or worse.
Q3:
is the clutch MC full? and does not drop day by dead week by week???


q4: new clutch
all 5 parts? or more?
PP pressure plate
disc.
throw out bearing
flywheel pilot bearing (oops?)
new slave cylinder? ,mc set

the slave and mc are a fixed pair in 2002.FSM C6-p9
and on my 2008

the slave and MC are one part and pre filled.
there is no bleeding steps only top offs.

if the clutch drags,(seems it does)
put in a new MS/SLAVE first.
avoid the 10hr labor. if a new clutch, 4wd.ad4f429a-1dc7-4f8b-aa26-1116f5bce673.jpg


I have lots more to ask.
trouble putting
so you are driving
and shifting and moving
and 1>2 shifts are what, grinds, or balks.

can you start engine in any gear (clutch to floor)

can you shift any gear parked ,running, and clutch to floor and not moving. including REVERSE ?
if all are good, cept the 1>2 upshift
that means the clutch is not dragging.
and the #2 synchro ring is worn.
or running the wrong trans fluids.

the newer transmissions are very tricky here.
some are very upset with wrong lube. (or too low or is not black as tar)
or mixing 2 brands, or using synthetic and its so slippery the syncrho fails, (cured many like this)

if all this is true, and clutch don't drag (ever)
then get the car to jeep and have them drain it and fill it with the correct lube and win.


now answer 3:
it might be just the shift linkage messed up
if the 1>2 change balks. (not grind)
on mine boxes i can hear the synchro's spin up.
i can feel them engage, if i cant feel that
then the linkage is bad.

the word trouble does not say what that means.
define trouble putting....

find a shop, a Service tech, that owns a m/T box.
and win.
Some with a/t are clueless...
ive blown more clutches racing than many ever drove.
IMO, and remember it COST YOU NOTHING to ask. (I'm retired early, gin!)

Clutch problems


Hi bosslady15,

First of all I think I should say that clutches do not make grinding noises - but transmission gears do.
However, a clutch that is not disengaging properly can make the gears grind when trying to shift from one gear to the next. Also a common source of noise is the clutch throwout bearing. This will make a "grinding" or "growling" noise any time the clutch pedal is depressed. In either of these cases, the only solution is to replace the clutch, throwout bearing, pressure plate and pilot bushing. These all usually come in a clutch kit. If you have an hydraulic clutch with an internal slave cylinder it is recommended to replace the slave cylinder as well and also the flywheel on on vehicles. I'm sorry I cannot be more specific because you did not mention what type of vehicle we are talking about here.

If you can put it into gear easily without the engine running but it grinds or is hard to put into gear when the engine is running then the clutch has not fully disengaged. If the clutch does not slip once you are moving then the clutch is not likely the problem. Instead you will have a faulty clutch slave cylinder and/or clutch master cylinder. The best thing to do is have both replaced and be sure that they are properly bled of all air. If the clutch does slip then it will of course need to be replaced, and be sure to have the pressure plate re-surfaced! Then there is the possibility, albeit rare, that all three need replacement.

92 jeep cherokee, manual, gear shift resistance


hi, if when you put it into gear and you lift your foot off the clutch then if your engine revs up without the actual power going to the wheels like when you say the revs change this indicates that your clutch is slipping, i wouldnt say their was a problem with either the cylinder master or slave and i wouldnt say it needed flushing out the problem you are having it that your clutch is slipping due to it being to low.

You need to get the clutch replaced sooner rather than later due to the fact that if your clutch plate shatters due to it being running on the rivets and not the actual clutch plate then this can cause the clutch to collapse and this will then cause damage to the master and slave cylinder and if you was driving at the time you would have no clutch at all and the car would be stuck in gear and you wouldnt be able to tow it as it would be stuck in gear.

You need to get the clutch and pressure plate the thrust bearing changed this will then solve your problem.

let me know how you get on or if you need further assistance ok

You need to check the clutch hydraulics i.e. the clutch master cylinder and the slave cylinder for their function, even if its cable operated try to adjust it so as it opens the clutch fork a little more to allow the clutch plate to be free,thus easy selection of gears.
If this fails thn you will have to replace the pro-kit i.e. clutch plate, pressure plate and release bearing.
Hope this helps!
