Could you please help a layman? I don't want to get caught on a remote trip with the clutch going. What are the tell tale signs, and

1) are you more likely to first feel it slip in 1st gear on takeoff, or 5th going up a hill?
2) Is it more likely to slip in high or low range
3) Once you feel the first slip, how long before you are immobile (can you limp home if you are on a remote trip)

Thanks in advance

Hi Chris you will feel it slip in the higher gear (3,4,5) also you will notice that as you shift gears the shift will take a while to totaly engauge the gear IE slipping . When it gets real bad you will have trouble selecting reverse . Note if this is a nissan 3ltr diesel they have a duel mass flywheel type clutch and are over $2000.00 to replace so dont leave it too long . Maybe take it to a mechanic to check out ASAP !!!

Modern clutches should last for 200,000k unless the vehicle has been towing, the thickness of the driven plate is the best indication of condition. You dont say what vehicle it is but most have a cover bellow the clutch that can be removed to inspect the edge of the plate. Measure the distance between the fly wheel and the pressure plate, it will be about 8mm, if its 6mm you should be checking it agianst a known good plate to see what is left. Eric.

If you can't measure the plate thickness, the very first signs are:
You need to press the clutch pedal way down to the bottom for it to disengage and change gears (and even then sometimes it is hard to shift gears).
At the same time once the gear is in, the clutch doesn't engage (vehicle doesn't start moving) until the clutch pedal is getting to the top of its travel.
If you already felt it slip once, that's it, needs to be done ASAP.
The more it slips the hotter it gets the less it will last.
If you already felt it slip once, it can leave you stranded, yes you can limp home (sometimes) depending on how careful you are and where you are, (in the bush on steep terrain not a chance) but by then the repair bill will also be huge and the increase temperature (due to slipping) causes other problems such as weakened springs (in other components) and burned gearbox imput shaft seals, so if it slips get it done!

How many clicks has it done Chris??
What sort of driving, eg lots stop start ?
Should last up to 150,000-200,000 maybe less if city car.
My Triton was getting down at 160,000 but its probably lighter than Patrols etc.
Thank God for low tech, it only cost around $225 for complete kit from Repco & 100,000 later its as new.
Clutch can still be "worn out" & not slip. Try putting footbrake on hard, put car into 3rd gear or 4th, rev to say 2000 rpm & let the clutch out gently. If it tends to stall no slip.
If it starts to slip depress cluctch immediately.Then get your new clutch.

Gday Chris,

as l dont have x-ray vision l have fitted new clutches to the 2 different secondhand toyotas l have bought before l did any major trips.

My reasons are : l dont have x-ray vision to check the wear & condition
clutches dont allways tell you the're about to fail
l cant be sure how the clutch has been treated before me
once l have fitted the new clutch l now can be sure of its history.

If the old clutch is in ok/good condition l take it with me as a spare that l know will defenetly fit and its a hole lot easier and cheaper to replace it at home at the time of your choosing than somewhere like the Mitchell plateau.

Regards Mitch
