1.4 TDi oil pump / balance shaft chain and chain tensioner replacement.
- Thread starter Little Dog
- Start date
Combination of wear and extent of remaining tensioner travel the available arc of movement is not that much
Do you have some photos that the tensioner is not able to absorb the slack, or there is no room for it?
Would like to see the guys in the highest milage club report who has replaced the tensioner/guides. I guess just a minority.

Replaced mine at 280,000 miles, no symptons but it needed doing
Replaced what was managements car at the time at 160,000 miles, it needed doing as well. this also didn't rattle i replaced it as a precaution, just as well .......

As I stated earlier in the year, it really should be a service schedule item to be done at the next cam belt change following the car having done 100k or so miles, given that failures have been reported on cars with not many more miles than this.
This figure was partly driven by the same observation I made that service history is simply not a reliable indicator of the extent of any wear - I don’t know what causes the seemingly vastly different wear rate from one to another - it must be something to do with usage and / or driving style and habits.

Mine rattled on hard acceleration; that's why I did the job.

@philward thanks for this thread, very informative!
As I'm planning to extend the life of my purchased ATL to the maximum possible (or allowed by government rules...) I ordered an oil chain/gear/tensioner set.
I ordered a Febi kit with 3 gear wheels. When it arrived I was disappointed.
All the parts were loose in the box, shuffling and damaged. At the tensioner one of the guides (polymer or composite plastic?) was loose. The tabs which should hold the guide was broken off.
Wrapped up everything and returned to sender.
Now I've ordered a Borsehung B18848. And what a nice kit it is!
All 4 gears are included and is send in a box.....wow.... The wife thought she was getting a present ?.
Hope it's quality stuff.

I think if they wear much further than, as in your picture, the slipper pad material breaks up and comes away from the tensioner. Then I think things get noisy and the chain breaks. I can't say for certain though because I've never seen a broken chain.
I my case I would have been happy to replace just the tensioner, which was badly worn, the chain and sprockets had very little wear.

Two weeks ago I had the chain, tensioner and sprockets changed on my TDI90 by my friendly local mechanic, along with the cambelt kit at 123,450 miles. He said it was slightly worn, but not badly. I honestly can't tell the difference, but it is peace of mind. He also replaced the aux. belt tensioner and belt as the tensioner was leaning at a funny angle and obviously worn out. Here's a link to the brief video he took before starting the re-assembly.

Thanks for that Matt. Will be opening up my Tdi later in the year, so interesting to see whats inside.Two weeks ago I had the chain, tensioner and sprockets changed on my TDI90 by my friendly local mechanic, along with the cambelt kit at 123,450 miles.

@BiggDogg, I noticed there are cut outs made to your gearbox for the sump too? If I remember correctly, you've got a 6 speeder too, or is/was it a JDD Bluemotion one?
Anyways, today I changed the crank bearingcap bolts to 12.9 version bolts, replaced oil chain, tensioner, and gear wheels and the timing belt including water pump, tensioner, roller etc.
It was a pita to get the sump off, because the 6 speeder kept holding it. So I managed by loosing the black tray between hanging sump and finally it gave way.
The gearbox was attacked with a grinder when the sump and oil pump/balance shaft bracket was removed, to make sure it would go on again without fuss. It did.
Piccies;
1st is old chain, is also close to the casing.
2nd is new chain, much room again, I was amazed!
3rd just a random piccie
4th, @BiggDogg screenshot from his movie clip. Notice (again) cutout on gearbox to acces bolts and to remove the sump.
