You dont want to pull the front off the pump without being able to time the pump! I would get whoever changed the seal to check they timed it properly. 

He said he didn't touch the Timing when he changed seal, supposed to be Specialist but has not got facilities to bench test or test with Gauge, so gonna have a look myself and order Digital Gauge, If the pump has been knackered along the way just have to get another.

Hmm. If he removed the front to change the seal, he has disturbed the timing whether he wanted to or not! There must be a reason for it, but I never understood why there wasn't a keyway in that shaft to set the front where the pulley connects.

I dont know the process for setting the timing on these in detail, but others on here do, and with a dti, you should be able to do it I think. Hopefully someone will confirm the process.

Just ordered DTI Gauge, so will have a go

Slacken off the 3 small bolts that hold the timing gear to the injection pump hub & take the timing belt tensioner off. 

3 Bolts are slack Mate, shall I take the Whole Tensioner off, Then put belt on ?

Yes that's how I do my 200tdi's timing belt. 

OK Mate will give that a go tomorrow, been on a sold 2 hours trying before 🤐  Ill get the bloody thing on tomorrow, then if its still the same, its Got to be something to do with Pump.

I think that in one of the Britannica videos, Mike shows how to be sure that the pulley is put on with number 1 port in the correct position. He basically says “don’t panic if you’ve taken it off, just do this”.

Tried that but still no see different, seems like the Belt has Shrunk, wonder if it's got anything to do with getting Diesel on it

That kit is only going to allow you to set the timing marginally more accurately than you are doing now using a pin in the front. If you have already got the pin in the flywheel and one in the pump then it will hardly alter. Just a bit but not to cure really bad running. It's more likely as has been said already, that the hub hasn't been put back correctly, so it is allowing the pin to go in even though the pump is out of position.

Spend time to watch the Britannica video that shows how to put the hub on with the pump in the correct internal position. Then time-up the engine with the pump back in place as you have just done. Here it is: 

 

Also check that you aren't in the incorrect flywheel slot (as mentioned earlier) and that the timing mark on the cam is perfectly lined up too.

Watched the vid but don't really want to take front hub off Pump unless I Really have to, Every thing is set up but say I was in the wrong Flywheel slot would the marks stil line up and Pin go in ??

You know when the right flywheel slot is roughly in place as the woodruff key on the crank lines up with the mark on the timing case (i.e. the key is at 12 o clock).

Gut feeling is that in changing the seal on the front of the pump, the person who did it disturbed the pump timing - I dont really see that they have done the job properly without retiming it?

Yes

Just to add to that, I added a link to the video. Is that the one that you have watched? The line-up of the front hub/pulley is checked right at the start of the video.

Key at 12 and pin slots in Nicely on Pump.

Watched  them all, the Diesel Guy said he locked the pump before removing the pully but don't think he did, as he said he could only check timing if pump was back on the engine,

so should I take the front pulley off ?

I have about the same experience as you. I have changed my belt just once but didn't need to remove the pump.

If I was in this situation I would check a dozen times that I really have set the timing correctly and am not a tooth out on the belt.

The pin should go into the pump at around 11 o'clock.

Once really sure then I would either:

  1. remove the pump and take it back to the guy who changed the seal or,
  2. follow the advice from Mike on that video and check for myself that the pump shaft is in the correct position for number one port.

Then I would re-fit, time it / do the belt tension one more time.

Think I have already checked a dozen times, Flywheel pin drops in at 12 oclock then pump pin slides in perfect at 11, marks on Cam lined up spot on.

Is it seen Visibly if it is a  Tooth out ?

Cant get no sense out of Diesel Guy he hasn't even got the proper facilities to bench test as soon as I do find problem I will be asking for money back if the fault lies with him.

Will go with Mikes info when I get me Kit.

I wouldnt remove the pulley yet. When your DTI arrives, you can check if it needs removing and if it needs taking off, do it then.

Is this a 300tdi or 200tdi pump? I dont think you cant lock the 300tdi pumps but the 200 you can

 

Edit - just looked back - its a 300tdi. I dont think you can lock that pump so I dont know how he did it. The 200tdi's have a bolt where you remove a spacer, do the bolt up and it holds the shaft in place.
