300tdi timing belt intervals

[Lucas]

Hi,
Just wondering how many k's between timing belt changes on 300tdi.

Thanks.

the previous owner of my rig did it at every 80K, have just had mine replaced at 240K

I had one break at 69000km.

What does the manufacturer recomend.

was this pre mod days.....all tdi's should have the mod kit fitted by now

Yes it was but how much difference does it make?

I'm not sure it's that simple. I couldnt find a reference in my owners handbook or RAVE. And that would have been pre-fix anyway. And there a few flavours of timing belt fix as well. What I've heard is if you doing heavy towing or lots off road - do it at 60k, otherwise 80k.

i believe heaps, from memory the fuel pump is aligned properly and a change in the design of one of the pullies...........something like that anyway

my non dealer lady repairer says 80K is the go......guess i'm hoping there experience is correct

If you do a search on 300Tdi timing belts you will find a huge amount of information.

The most common figure quoted is 80,000km although as already mentioned 60,000km is a safe bet.

If you have all the mods done and the belt is installed and tensioned properly most seem to be able to get a 80,000 to well over 100,000km and when replaced the belts look in top condition.

My car when purchased had done just over 80,000km and the belt looked near perfect when I replaced it. Their was only a hint of fine dust inside the cover. I am glad that I did it though and will be replacing mine between 60,000km - 80,000km. Having already done over 10,000km in about six months I have got at least three years ahead of me.

However we replaced a friends belt and there was only 3/4's of the belt left. It had about 80,000km done since the last belt so it pays to be safe. We would have hated having to replace rockers and rods etc if the belt had given way.

Remember to check the front cover bearing when doing the job as they have usually had it by 200,000km.

Just did mine, 60,000kms or just under since it was done last but just clocked over to 300,000kms so I thought id get all the big stuff up to date.

Not a hard job if you take your time and yes I agree, check the fan bearing before pulling it all apart and maybe set up with a press and sleeve to replace it if need be.

By the way, there was heaps of junk inside my cover BUT I do a fair bit of 4wding and a fair bit of that is in muddy stuff, water and dust so that wasnt surprising as I never have fitted the wading plug :p

The belt looks perfect other than a bit shiny in comparison to the new one and the 200TDI Idlers work fine as well as I have the updated crank shaft pulley with the sides on it.

I found that the economy started going bad and it was getting hard to start when cold which says to me that it was retarding the pump so the belt had stretched so was due for replacement in my eyes.

That might be a load of crap but makes sense to me.

Good luck with it and yes there is plenty of good advice on here.

The things you need to know though is 9.5mm drill bit is a good pump alignment tool and dont tension the belt more than 20Nm.....doesnt sound much but apparently that is one of the reasons they used to fail prematurely.
