Hello Guys, first sorry for my bad english, my problem is with an Astra F 1.7D. The timing belt's side worn, original size is 24mm, now 14mm. After the injection pump there is an idler, and the idler's edge wears the timing belt. I had 4 Opel Kadett 1.6d-1.7d (Vauxhall Astra mk2?) since many years, and on that no problem like this on MK3 Astra.
I made a photo from it.
Thank you very much if you can help me an answer.

wow you had better replace the belt and all the timing components ASAP! Somehow the belt (or possibly the idler itself) is out of alignment.

That's amazing that the belt width is worn down that much. From your picture it looks like the inside edge has been worn away is that right? Anyway I'm thinking that the belt is constantly being pushed against the idler edge

Maybe the underlying problem will become clear as you replace components. I recall that I found my old tensioner nearly fell apart in my hands so I suppose it wouldn't have guided the belt very well.

p.s. just wondered if it at all possible that some muppet somehow installed a narrow belt - is there any sign of all the belt debris that would have come from the 24mm belt?

Thanks Paul, i changed the idler with a new one, and a new timing belt, and i still saw many crumbs from the timing belt. Some people said here, the problem is in the injection pump with the bronze bushing? or with the thin aluminium console, who is holding the injection pump. Unfortunately here only used parts with this old astra. :(
 
Ah yes I think I understand. So how well did things line up with the new belt and idler? Did the belt appear to be jambed up against the idler? I wonder if you could replace the "bushing or aluminum console" on the injector pump? Find some replacement parts at a wrecking yard maybe?
 
Thanks Paul very much again. I was owned an Astra since 10 years ago, same 1.7D engine, and that engine fitted with Lucas pump, but was some problem with that pump, i changed that a Bosch injection pump, from an E Kadett. When i changed, the idler start to eat my new timing belt. :(
Today my friend told me, maybe the tensioner is the problem, when i tensioned to the wrong direction.
Tomorrow i will try it.Fortunately not a big problem if the belt breaks in this engine. :)
 
Those bosh pumps were notorious for dying, costed a bloody fortune too.

Gotta show some pics of your car sometime!

Welcome to the club by the way!

Where are you from, if i may ask :)
 
I've had my belt rub and cut in half on a 1.4 8v, it was due to the tensioner. Couldn't tell (hence why I didn't replace it to begin with).

Hopefully its just the tensioner in your case too
 
Helo FrostyHound, i think the Bosch pumps are ok, if the fuel is leaking from the pump, enough to put any pressure valve before the injection pump. But the CAV pumps everytime problem for me, because of seals.
My car looks terrible, rust everywhere, it's a white sedan Astra. But it never welded, and broken. :)
I'm from hungary :( and i think my Astra is made in Szentgothárd, that's way it's not to good condition, my previous car is german E Kadett 1.6D, and never had a problem with it.
 
Thanks Mr.Negative, i don't want to change the injection pump, and the retaining bracket. I hope too, it's only the tensioner, but i didn't saw yet, how looks the timing belt now :( but now it's time for me to see.
 
We like a rougher looking Astra, i prefer em over fancy polished gsi's!

Greetings from Belgium!
 
I think, found the problem.
The 49872346 piece water pump? which you can buy at the store...
It was mounted on the wrong type. :(
 
Sorry Paul, i didn't mean, I thought that a lot of type, size, etc... water pump in the store. :)
I just wrote a number. :)
 
Hmmm, well, like I said in my first post in reply to your initial post - I reckon you need to replace all timing components, belt and all. New water pump, new tensioner, tension roller, and new belt. Just better to start out fresh and with correct parts.

I recall when I did mine I found that the mechanic who had recently done the job never replaced the water pump (I think because he couldn't find the correct part in NZ). It started leaking and needed replacing.

Then I found the tensioner nearly fell apart in my hands. I did pay for a tensioner but I think this may have been the original. The tension roller was indeed the original and made a horrible grinding noise so was shot.

My copy of EPC doesn't work any more but maybe somebody on here can tell you the part numbers, then you could buy on-line using the genuine part numbers to search, even if it is an aftermarket version of the part required (like the QH parts or whatever).
 
Yes, absolutely right. But the water pump was completely flawless, I changed only the two tensioner.
My old 1.6d Kadett's water pump lasted a long time, i think 3 belts.
Thank you very much for the link of water pump, now i see it's only £2.95? :)
Better, to change all part now. :(
 
Questions to Mickey74:
What year is your Astra 1.7D ?
What engine version is it fitted with (ie does it have a low blow turbo, in which case the engine is an X17DTL) ?
(I don't think the Ebay water pump you referred to fits the X17DTL engine).
 
Helo Andy, my Astra is from 1993, and it's a simply 1.7d(17DR) engine, no turbo on it.
And i saw other thing, the injection pump's wheel not paralleled with the tensioner, and with the idler.
Some days ago i put a spacer? behind the idler. Now better, but not perfect. :(
I hope you can understand me.
 
It sounds like things went out of alignment when you replaced the injector pump with the Bosch. If it doesn't line up with the tensioner I imagine it doesn't line up with the camshaft pulley either - is that correct?

So maybe there's a way to get the Bosch pump pulley to sit where it needs to be to line up with the other timing components. If not you may have no choice but to go back to a CAV pump.

I was looking at diagrams just now and see that there was either a Bosch or a Lucas pump fitted. Wonder if it got changed at some point and resulted in mis-alignment...? Don't know

anyway here is link for you to explore parts etc http://www.partsbase.org/opel/astra-f-1992-1998-7-fuel-and-exhaust/

Great link Paul, cheers.
OP, and anyone else looking for parts, I found a nifty site for searching for parts that fit your EXACT model, so I thought it was worth sharing. I had my own timing belt / water pump issue recently and found the part that I needed to track down here: http://car-parts.mister-auto.co.uk/en/timing-belt-kit-with-water-pump_lg3096/

Just enter your car's specs and voila ! Hope it helps anyone.
