ive got a skoda octavia 1.9 tdi 110bhp and ive noticed that the aux tensioner has broken at the alloy bracket can someone please give me some advice ie part number if it wasy to replace and how much it costs many thanks

It's easy enough to replace.

1. Use a spanner on the flats (15mm) and release the tension on the belt.

2. Put a pin in the hole to hold off the tension.

3. Undo the three mounting bolts (13mm)

4. Remove the tensioner, leaving the belt in place.

5. Examine the belt for damage/excessive wear and replace if necessary

Put a pin in the new tensioner and fit it. Remove the pin whilst taking the strain with your spanner.

but you no a part number becaus e there are a few different ones so they say

Have a look on the Jorilly Skoda website, I think that theirs is the cheapest at around £53, assuming that your car has the ASV engine like mine. This is for the one with the damper type, dearest of the lot I think.

This one I think;

Skoda Octavia 1.9 TDi Alternator Belt Tensioner (Damper Type) - £53.00 : Skoda, Audi, Seat & VW Parts, Jorily - Probably the UKs largest independent skoda parts supplier

Check the one way cluch is working on the alternator pulley too.

I believe that if it fails, extra load is placed on the belt and it can cause the casting on the tensioner to fail.

Checked mine when I changed the tensioner and the pulley rotates the alternator in both directions, so I guess that I had better think about getting mine changed soon :(

Hi

I realise you posted this nearly a year ago, but I'm wondering if this was the same problem I have...

In my case it's not the actual damper or the tensioner that are broken, it's the alloy casting that the damper mount by the power steering pump. The mounting point has sheared off, so somehow I need to identify this part and figure out where to get a new one and how to replace it.

Thanks

And now, two and a half years later still, I have the same problem - the top of the damper mounts to an alloy bracket, and the casting has snapped, thus allowing the damper to fall onto the pulley and there are bits of alloy all over the place! Can anyone supply a part number and/or helpful hints for replacing the bracket? Do I need to think about replacing the alternator pulley and/or the damper and/or the tensioner assembly too? (The car has done just over 120,000 miles and we have owned it since new.)

The tensioner often breaks as a result of the pulley on the alternator having failed. I recall there was someone on here 2 years ago who broke several tensioners before replacing the knackered pulley.

In my car the pulley sheared off and I was left with no power steering, etc rather than the tensioner breaking. I replaced the tensioner when I was doing the job (around 150k, maybe?). If you know your engine code, then any half decent parts supplier should know the part number. Or phone up your local Skoda dealer, quote your chassis number and they will tell you the part number.

When I removed my alternator, it was a bit of a pig. PAS pump out and larger rad fan moved to one side. After several hours of wiggling (the bushes were jammed) I was able to lift the alternator up and out. Fitting the new pulley requires a special tool (I got a local VAG place to do it for a few beer vouchers).

had this happen to while short while ago it snapped loads of alloy all over the place and slightly ripped belt too had it replaced, couple hopurs after getting the car battery died took it back and found out he didnt check the pulley on alternator when he did this found it was stuck so had that replace too and havent had any problem with it since apart from my turbo sticking lol

My tensioner has just broken off on the corner of the housing. If I try to hold the tensioner (still attached at bottom) it vibrates rather a lot. I am assuming this means my alternator pulley is failing and causing vibrations and tensioner to hosing to snap off?

The pulley on alternator is designed deal more with a change of engine revs (as I understand it) so just because there is some vibration at I am guessing a constant rpm that might not be the issue.  However things dont break with a reason so the pulley would be the prime suspect - they always seem to fail during the winter months too - maybe due to the extra load on the alternator.

 

It is possible to check the freewheel on the alternator pulley with the unit in place (although I didn't bother as mine was hosed!)
