2009 Ford Ranger Clutch Failure @ 25000km

Poor operator/driver usage/technique.

Train operator/driver to not ride clutch pedal when not changing gears.

Alternatively replace manual gear box with an automatic, or replace vehicle with one fitted with an automatic.

100% sure of Poor operator/driver usage/technique.

With only the information given, yes.

We dont have parts now, so this vehicle still running, but more racing it not move. It can move has a driving tecnic. that vehicle was drive maximum speed 20 KM only, that is the reason or what???

If you continue to operate the vehicle with a slipping clutch, you will encounter further damage.

Instead of just replacing the clutch you will require the flywheel to be machined(if possible) or replaced.

The vehicle will let you down in the most inconvenient way if you keep trying to operate it. Leave it parked, arrange for the parts and someone to do the repair.

Firstly, poor driver is 90% of the equation with premature clutch wear, sometimes design plays a role as does vehicle load, number of hill starts made, how good the clutch adjuster does its job human or mechanical!).

Furthermore, diving it now will mean that the flywheel will also be damaged and treble the repair costs.

On some cars you can replace the clutch by simply moving the gearbox back or out, to replace some flywheels involves far more work on many vehicles, sometimes engine out even, so that also increases costs...

STOP DRIVING IT NOW!!!!

Do not forget to also replace the release bearing, even if still in a good condition....they often cannot go as long as 2 clutches and are cheap and easy to replace....

See Post #1

Overall mileage alone is meaningless. HOW the vehicle was driven during this mileage IS critical.

In my old (now retired) Ford, clutch replacement was necessary at ~230000 km (~7 years). The vehicle was used for daily driving (minimal stop & go), frequent long trips (200-900 km) at continuous highway speeds (>100km/hr), and some (legal & fun) drag racing at a local track. I suspect my drag racing reduced the clutch life about 30000 km of normal driving.

If the driver is inexperienced and the usage is "taxi" duty (continuous stop & go city driving) and/or heavy load hauling, one should expect HEAVY clutch wear. Failure at 25000 km seems possible under these worst-case conditions.

This truck dives in US Military base only. Here speed limit is walkig speed. This is a reason for clutch wear or? I want to know driver/manufature fault.

The stock clutch on the Ford Ranger is not a heavy duty type...if you are using the truck for hauling or towing, expect the clutch to be short lived, especially if you back the vehicle loaded....There are heavy duty clutches available...Is this a 4 wheel drive?

Thanks, It is very useful link. I am trying to replace this.

My questian is it is driver's fault .... sure

the original post did not give enough information to define whether or not hte driver is at fault. I would suggest that rather than look to the driver you look to who authorised the driver to operate this vehicle, who authorised the purchase and whether this vehicle was fit for purpose.

As a previous poster said, this is a light duty truck and if it was assumed it can operate outwith the design parameters then that is the root cause fo the failure.

If you hand a hammer to a guy who needs to hammer something you'd better be sure it's the right tool for the job! Same applies.

There can be any number of reasons for the clutch to fail....The driver can not be blamed without a track record of repeated premature failures, and only then if the truck has not been used to haul heavy loads or tow heavy trailers....I would give the driver a pass and replace the clutch with a heavy duty type and review the weight being hauled and/or trailers being hauled to make sure the truck is not being asked to do something it's not equipped to do....

"that vehicle was drive maximum speed 20 KM only"

Is that 20 km/cucumber? Speed has the wrong units. From context, I get 20 km/h.

Back to the clutch problem. Just take a look at the number of gear changes into 1st gear and look at the driver's technique shifting into first.

I would classify slow movement as heavy duty as would i classify heavy hauling.

It would also appear that an automatic transmission would be better suited for a task of "basic transportation". There may be "other" reasons why a manual transmission would be appropriate and a "Heavy Duty" vehicle should be chosen.

Let's go back to premature failure. I had a car that had that problem too. Clutch failed at about 25K twice until I physically did the clutch replacement. A BIG BOLT was probably missing from the factory. I knew something had happened based on the sounds I heard. The throwout bearing died.

After that replacement I started getting normal lifetimes.

An improperly adjusted clutch linkage will cause the same wear as poor driving technique. Therefore, it is impossible to judge with certainty which is responsible for your failure without further information, As a matter of fact, if the clutch linkage is not adjusted so there is some free pedal play, your clutch may not be worn out, it might simply require adjustment.

I had a mazda b4000 (ford ranger 4x4) in the states. Was a 2000 model and at about 150k miles the slave cyclinder on the clutch went out. Was told by mechanic that the clutch had only used half it's wear life.

Truck used to occasionaly pull a trailer and mostly small town / highway use.

I am a very experienced driver (with commercial driverslicense) and I do most of my own maintennance (but haven't done a clutch yet).

.

That being said, even with my driving experience I would expect the clutch in a vehicle on a military base at 20km/h to not last as long as normal. Lots of stopping or slowing for troop movements and such. It is very heavy use.

In those conditions I would expect an experienced driver to make a clutch at least 70% to 100% of its normal life but someone without as much experience (driving or mechanic) to last 50% to 70% of normal life. Inexperienced drivers tend to slip the clutch more and over-rev or under-rev when starting off.

My 2 cents : )

If the truck is only driven at slow speeds, It will wear out faster just because it is not accumulating miles in high gear. And how many stops and starts per mile is it doing? And, how many times does the driver decide to not put it back into first gear? Locate a clutch re-builder, and explain the problem to him. He may be able to find a larger diameter clutch assembly from a different application. And certainly, a better friction material should be available. If all else fails, try this. When I first started working in the automotive field, my boss would put a brake shoe return spring on to the clutch pedal. Just an incentive to not let your left foot push down on the clutch pedal unnecessarily.
