Car Wont Stat After Cam Belt Change

[Shabazmo]

Cam belt and water pump replaced and now I have a problem. The aux belt tensioner is very stiff. I can move the lever after disconecting the roller and putting a deep socket and ext bar over the lever. But when the roller is connected and I use the roller bolt to turn the tensioner, the bolt continues to turn and I will probably shear it if I continue. I have put plenty of lube on it but am running out of ideas. Any suggestions?

Thanks

Did you do the job yourself ? and did it snap while the engine running ??

 

if so sounds like something moved when refitting, Check your timing marks !

Yes all my work and all was well before I started.

I may have found out what is wrong. My TDC marking established by looking at the flywheel may have been flawed. What I saw was a reasonable dimple with lines either side of the dimple. Having inspected the flywheel all around the circumference, there are 3/4 of these around the flywheel. I then removed glow plug No 1 and put in a long BBQ scewer and watched it rise to TDC. My original mark was slightly off the highest point. I can now see a micro dimple further along which is at the centre of the flywheel width. It is so small that I cant be sure. Can anyone advise whether I am looking at the right TDC or is there another mark. Engine is AFN 1.9tdi 1998 110bhp

Hi there

You havn't mentioned the position of the camshaft and injection pump, did you mark these with tipex or paint, or have you the locking tools for the cam and pump?

If you have used the incorrect mark on the flywheel you will need to check the camshaft and pump position, at crankshaft TDC using the method you described to find TDC, remove cam cover, you should be able to engage a suitable size bar in the slot at the end (gearbox end) of the camshaft when it's on number 1 compression stroke, also a suitable size pin to lock the pump.

 

In retrospect if you had aligned the cam and the pump first before removing belt you would have seen correct dimple on flywheel.

 

Let me know if you need pictures of the checking points. ;)

I locked the camshaft and the fuel pump, so they are fine. I could not find TDC on the flywheel and used a scewer in no 1 glow plug to find TDC. The car now runs well. How can i check if I got TDC spot on. Can vagcom help with this by checking the fuel pump timing.

Thanks
