The tensioner is mounted by the lower bolt, however you first have to remove the belt

View attachment 139304

It's hard to get your head round if you haven't done one before, you have to place a large ring spanner over the bolt on the roller and rotate so that the roller moves downwards.

There's a fair amount of tension on it, it will help if you have an assistant to slip the belt off while you do the necessary with the tensioner.

You'll get there

All the best

The tensioner on the 2.4 engine is a bit different to the 1.9. I'm guessing the above part is what you are talking about? The pivots seize and stop it 'springing'. To be honest its not an easy job to change as tensioning the belt can be a struggle. If you search you'll find answers but there is another eccentric pulley to the right that is twisted to tension the balt against the spring tensioner.

+1. The tensioner on the 2.4JTD differs from the one on the 1.9JTD. I hope they are more reliable. The tensioner on my 2.4JTD lasted 13 months. Just outside its manufactures warranty!!!

 

Be careful undoing the bolt that holds the tensioner to the block, they can seize and snap off leaving you with a nightmare to get it out, if it feels at all tight work in back and forth gently helped with a bit of spray if you can get it behind the bolt

 

Hi Keith. Was it you that started a thread a while back showing how to free up the tensioner??

I have overhauled the tensioner I removed after 13 months of service. I did consider offering a service to forum members to overhaul them. There are a couple of problems with this though. Firstly I couldn't find a manufacturer who would sell me a direct replacement for the bearing or spring. I came up with a method around the bearing but the spring was a non starter.
I even went as far as getting the tooling and spares.
I'm not sure how many failures are spring related but for me the three that I replaced, two were related to the pivot shaft/bushes wearing causing the horrible rattling and one was the pulley bearing squeeling. My method of overhauling cures both these issues.

 

Nope not me. I just followed someone elses tip! My bearing and spring were fine but the pivot had just started to stick. I caught it just in time as the bush was fine. I''ll probablyhave to replace the whole thing next time as the bearring will probably be going but at £100 a shot it had to be worth a punt!

someone was saying theres no grease in the allen key bit (if you know what i mean)
and to grease it up your self, yes steve thats the tensioner im on about found it for £103 at euro parts.

 

someone was saying theres step by step instructions on how to change the tensioner on here
anyone know where it is?

 

Help help please, Ive know changed the tensioner, and put the old belt
Back on, all was going well and then the outside of the belt started to strip
I put this down to the belt being old so changed the belt, all looked good no squeaking
Belt looked good nice tension I drove the car to work and back decided to check the belt and same
Problem again its striped the belt from the outside, I can't understand what's gone wrong as the belt is guided
Has anyone else had this problem help please...

 

Something is out of alignment. Check the bearings on the other pulleys including the alternator and Air Con. Also check that the new tensioner is sat correctly. Seem to remember that there is a thin washer behind the tensioner and there is a shallow counter bore that the pivot pin sits in.

 

Make sure when you fit the belt all the ribes are fited into all of the pulleys correctly...

 

Thanks I've just checked the belt and it wasnt in
The alternater correctly one of the ribs was hanging over
Off for a new belt tomorrow and start again thanks again for info.
