timing belt on 300tdi
Fitted new timing belt to my disco 2 weeks back.....and it snapped last night.....
Before fitting the timing belt, injection pump sprocket was loosen first. Then when fitted the belt, tensioner was tighten first, then tighten the injection pump sprocket (2 stage tightening).
New idler, tensioner, crank sprocket with revised shoulder was fitted.
So now, am wondering why the belt slide off and grind on the timing case cover???
Loose belt??? But the tensioner did not get loose when I open it up today.

I know next to nothing about diesels but I do recall seeing a problem with the revised pulley not going home all the way, even when fully tightened.
I can't remember the cause but it was as a result of upgrading from the old pulley style to the new one with the shoulders on it and the slight misalignment it caused had resulted in the belt being shredded. Even with everything tightened up fully when you actually looked across the pulleys one of them wasn't fully home.
I'd take a very close look at the alignment of all the pulleys and make sure they are all perfectly in line with each other.

Sorry to hear that Kingson - I hope that there was no serious inconvenience or 'collateral damage'

Ermm
A little bit worrying )
Since my new ride is on a Q plate and made up out of bits the VIN is probably no help at all.
If the weather is good this weekend or I can get a few days off I will take the cover off and do a visual inspection, the edge of Kingsons belt was all chewed up (the edge towards the front of the vehicle).
I will also recheck the tension from that informative but somewhat confusing link ).
Dave do you mind if I hang onto the torque wrench a bit longer till I get one of my own, I'm only a call away if you need it back, PS I also have a wing mirror for you that Kingson sent up with me, was going to drop it off tonight but we have had a kitten missing for 2 nights and my mind wasnt really with it.
Off topic but for the animal lovers, on the 3rd night of trawling the neighbour hood (in the pouring rain tonight), posters, 200 flyers through people letter boxes I was walking round the streets again calling out and I hear a pitifull whine from some old garages, to cut a long story short the kity is back and when the wife gets home I will probably racked up a years worth of browny points )

rocker cover off.......damaged founds are : 4 x bent push rod & 1 broken rocker arm.
Reason for snapped timing belt.........O ring not sitting right at the back of crank sprocket, hence belt was sitting about 2mm further out and was catching on the timing cover. am really gutted at that...but at least learnt something valuable...
Richard.....the o ring on your crank shaft dis not come off while fitting the new crank sprocket, so you may be safe......

Kingson, was it the crankshaft pulley on mine that you used the old pulley to as a cushion and hammered on it repeatadly make sure it was seated all the way on ? if so I am pretty confident all is good and prepared to leave it be )

woohoo....disco back on the road....
tried numerous times to get the crank sprocket seated in with the O rig, but always 2mm out.....so decided to go without the O ring, and it went in perfect......so final damage count......changed 8 push rods, 1 rocker arm, and 1 new timing belt...think i got off lightly...
