Frequent clutch failure

Hello all Iím new on here, having real problems identifying why my clutch on my 1.9 doblo is failing every 7-8k! Each time itís the release bearing that collapses. Iíve swapped everything including the guide tube and still itís failing prematurely. The vehicle isnít driven hard and clutch pedal isnít being used as a footrest!! Only thing Iíve not swapped is the clutch release arm that actuates the bearing and releases the clutch. Has anyone experienced similar problems-totally at wits end with this.

Re: Frequent clutch failure

Check the clutch release arm is not twisted have had that on other vehicles over the years I was in the trade, allows the bearing to come down not square with pad on cover.
Check for free movement as well in cable, pedal, & gearbox pivot arm

Ok.. so when did the last 'good clutch' fail.

In what way fid it fail..


The new ones?
How many clutches..how many bearings..

Distances covered etc..


The suggestion of an 'out of square push'

Sounds VERY plausible.

Re: Frequent clutch failure

Had 2 both on BL\BMC carbon release bearings I think they failed due to a damaged release before the problem started causing arm to twist the twist was not a really noticeable amount an 1/8 or so if you have box out put a strait edge across bell housing & measure either side of bearing to SE, do it at full travel & at rest, don't forget to check any bushings in Gbox if any & the other things I mentioned
Never looked at the Fiat clutch all ours did 150K without clutches or flywheels, so maybe a concentric slave cylinder, (still check for square if possible) did have the stupid plastic clutch cylinder push rods break though.

Re: Frequent clutch failure

+1 for 500e's suggestion of uneven release arm pressure. Check the pivots while you are in there. If one is worn or cracked it will cause a similar effect.

Re: Frequent clutch failure

Do let us know what happens longer term
