Seeking opinions of those that have gone before me.

Ford Ranger, 100,000 Km.

Sounds like the clutch is squealing when I decelerate, stops when it apply clutch.

Not complaining, got 100,000 Km from it.

Now the question, do I go OEM DMF or aftetmarket SIngle Mass Flywheel.

Seeking opinions from those that have done this, and their experiances after the job with their vehicle.

Does it affect your driveability?

I changed my Mazda BT50 clutch over at 24,000 km after it was giving me a hard time. Of course, Mazda denied any issues but I found out here were so many. Not to worry.

It has been the best thing I did to it. No more issues and it has now done 70,000 kms. It took my non Mazda service centre about 2 hours to do it.

If I was confronted with a new vehicle with the dual mass clutch, I would do it right at the beginning.

You will not regret it and there are numerous other makes that are having the same problem.

Duncan,

Was there any change to the "driveability" of your BT50 after the change over.

I have recently read that you can encounter noise and backlash from the drivetrain following changeover to Single Mass Flywheel. Have you noticed anything like this?

I'm not used to having to change flywheels and clutches like this.
Last ute I ran did over 250,000 Km before I changed the clutch, as a precaution, before driving 1/2 way around the block on holiday.

Initially I noticed a little more vibration but no more than the Mazda Bravo I had previously.

I have not noticed any other issues. The manufacturers have floated the backlash and noise. Have a look on the MAZDA BT50 forum and there may also be a Ranger site dealing with this item.

I mostly drag a 2 tonne Kimberley Karavan with it and it has been to some unusual places. All up the BT50 would have hauled the Karavan about 55,000 kms and some of it in 4wd.

If the clutch is working ok then it is ok, and the noise won't be the clutch, it will be the clutch thrust release bearing JUUUST touching the face of the clutch diaphram spring as it rotates and the dryness is causing a squeal. When pedal is pushed a bit, noise stops because the bearing then rotates and it's face isn't whistling on the diaphram fingers.

You may be able to add a clutch lever return stop to the lever and have the piston in the slave cylinder pulled back ever so slightly so there is no physical contact of the bearing on the diaphram spring fingers. I have done that on some vehicles to stop that noise.

So, maybe you don't need a replacement clutch just yet.

Ross,

Thank you for that information, will have to check it out.

Squeal only happens in 1st to 3rd, when I lift off the accelerator, but not in 4th.

Something else to ponder.
