tension pulley for fanbelt 300Tdi

[antvc]

The pulley (bearing) is starting to make noises. It doesn't feel smooth when I turn it by hand. I checked the rave cd and can't find the page which explains how to change the pulley or the bearing.
Anyone know what to do to remove the pulley ?

As a genuine part it is only available as a complete unit. Remove the belt (15 mm spanner / socket to release the tension) and undo the nut in the centre of the pivot point (also 15mm, from memory). Reverse procedure to fit new tensioner.

Hi Antvc
Do a search on 6203 which is the bearing you need,just bought one from bearing supplies for about $13.00.
Take off pully wheel, I filed a grove into pully wheel so as to get circlip off easier.
Push old out and new in.
Took a while but easy to do.
Did see pictures somewhere on this site.
Good luck.

Ah yes, should have thought to do a search. there was plenty of info after doing a search
Thanks for the assistance and the wealth of information that is on this site.
Will try and have a look at it tomorrow

yes very easy, did mine last week, I got my bearings for $3ea :p

Probably replace all of idler bearings while your at it. $3 or $4 each. Make sure you get bearings with seals both sides.

Also the idler pulleys for Holden V6 are interchangeable and much cheaper (not as cheap as replacing the bearings, unless you factor in the labour).

Just a warning, the cheap bearings are generally chinese and some can be good and some can be bad.

Normally a 6203 should be around the $7 to $8 mark trade so if they are really cheap, before you install them check them for play as a good quality one shouldnt have any noticable play.

Im not saying that you shouldnt fit the cheapies but just check carfully before you do as any movement you can feel in them before you fit them will be amplified when they are fitted.

I normally buy NTN which is chinese owned though they seem to make good reasonably priced bearings which seem to last longer than the real cheap ones.

[awabbit6]

I agree. I paid $7.70ea for good quality bearings.

[sclarke]

SKF are about $15 each.

Id prefer a good one over a cheap one...
Nothing worse than replacing it ever 50k......

Go the expensive ones...

[Bush65]

From memory I paid $4 each for FAG, which are a good quality German manufacturer. But it was 2 or 3 years back.

"replace it as a complete unit"?
Those were the last words I EVER heard from my dealer and never went back there again - What a load of Crap.
The bearing is a NTN 6203 17x40x12 standard unit and mine cost $5.61 plus GST from a local bearing supply.
Took about 30 minutes to replace.
Also take note (not before mentioned) that the centre bolt is LH thread (to allow for a socket to be pulled against the idler wheel to release the tension).
Do your research and dont listen to the first bit of advice you hear from a dealer (or someone who has never done it before)
Cheers - Matti

You only need to replace it if the belt keeps sliding off it or it's bouncing excessively.

Ive replace the whole thing once and the bearing then went about 8 months later but it had to be changed as it wouldnt sit straight and the belt would just be worked off as it was also bouncing badly so I changed it.

And yes, I forgot about it being LH thread.

if the whole tensioner does need replacing (eg. the spring has lost tension, or the nylon bush the tensioner rides on is flogged out or seizing, as mine started to look recently) it's much cheaper to buy a Dayco (identical to OE) unit from any spares place than even an import aftermarket part.
Dayco pt. # APV1004

I was told that you could only buy them OE by 3 different LR specialist workshops so thanks Rick130 thats gold.

I just ordered mine through Bursons last week, had it delivered within two days.
List price is $126 including GST, trade pricing is obviously much better. ;)

Did the same pulled it out and went to the local bearing supplier, they gave me about three to choose from straight off the shelf and also recommended the mid or dearer one due to the seal issue. (Cheapest only had a seal one side and I was warned not to use it if it is likely to be exposed to dust etc. I think I bought the "best" one which was around $12 from memory

Yeah sorry, I did pay $3ea for the bearings....But they should have been $6.60 (trade), but the bloke stuffed up when I rang and asked how much ($3, how many hundred do you want?)....at Least they stuck to the first price when I picked them up :)

[Disco300Tdi]
