I'm attempting to adjust the timing on my car as it is retarded too much according to vcds. I'm following the following guides...

Appears a simple process however I can't seem to get the sprocket to move? I've done all that's asked but when I try to turn the sprocket the whole lot moves. I've loosed the 3 bolts more than enough to let it spin. So much so I can screw them with my fingers. I'm stumped now?

Help appreciated.

Are you trying to move the sprocket, or the hub via the 18mm nut?

Obviously you can do it either way, but moving the sprocket usually requires one of those sprocket hold tools. Have you tried a spanner on the 18mm nut and tapping it with a small hammer or something. This might just break the friction between the sprocket and hub underneath it.

I've got a big spanner on the 18mm nut, It takes a good bit of pressure to turn it but when it turns the whole lot turns. And I can't move the window, they just turn together?

Have you tried tapping the spanner rather than turning it?

theres another guide incase theres any difference^^

have you tried turning the sprocket both ways ?

I've tried tapping (hitting it with my hand) but couldn't get it to move that way. I guess you mean in a way that makes a sharp movement to break the friction? Maybe it's siezed?

Just had a look through, nothing is jumping out at me. I'm pretty sure I'm doing it all. I just can't get the damn thing to move! lol I haven't tried going the other way as I don't want to retard the timing anymore. And the bolts are tight at one side of the slots so won't go round the other way.

Exactly....to try to break the friction between the hub and the sprocket.

Unfortunately the tension in the belt will really be working against you. You may have to fashion a tool to hold the sprocket while you turn the hub with the spanner.

Like the tool showed in the video in one of the links above? How would I do that? What would ya reccommend I could use, anything DIY?

Is it at TDC?

If so you could put a locking pin in (which would lock the hub) and tap the sprocket with a flat screwdriver and hammer to release it. I think you can use a 4mm or 5mm drill bit as a cam locking tool.

I'm not sure? How would I'd know if its TDC?

Good point.....it's hard to tell without seeing the crank sprocket.

What about getting a flat screwdriver between one of the 13mm bolts and the sprocket (in the oval hole) and levering it gently.

is there actually anything wrong or is it just because vcds says so?

Ill have another play about tomorrow, hopefully ill have better luck

The syncro angle is out of range, I'm trying to bring it back in

Speak to rapture, he recent reset his.

Hi,

Is the car running badly ?? poor perpormance smoking

You really need to get at the crank pully and set TDC with the locking tool first then see if you can get the cam locking tool in

You need to make sure that you are not 180 degrees out went setting or the tool wont go in any way on the cam wheel.

Cheers chris

No it's not, I just noticed this through vcds. The inj quantity and fuel consumption are increased also as a result. None of the guides suggest needing a locking tool to do this?

I assume you are just tweaking the timing, because the torsion value is a bit out.

In this case you don't need to lock it with pins...I only suggested it to try to get the cam sprocket to budge from the hub.

Yep that's what I'm trying to do. Had another go this morning and still won't budge! So frustrating

Just to add to this, called to see my mechanic tonight. He basically said it was a terrible idea to do this as you've no way of knowing where the crank is. That you need to have them locked it to set it. So I'm going to go back for him to strip it down and and re set it all hopefully. Job worth doing I feel. Hopefully the retarded timing isn't what makes my car go exceptionally well and as a result makes it slower :(

What was the torsion value in VCDS?

Unless it is way out, the chances are the locking pins will go in and the timing will look ok.......you're only after half a degree or so of tweaking.

Try loosening the 3 bolts and putting a punch on one of the 3 bolts and tapping it with a hammer, I've had one that was a bit seized and it seems to work well as the 3 bolts are attached to the rear part of the pulley and the front stays where it is as its attached to the cam belt.

Good luck mate

-7!? :S

-7!? :S

Ahh......In that case the cam locking pin will probably not go in at TDC.......best time it up with the pins and see what the torsion value is then.....then tweak it from there if you have to.

Car runs totally fine, if it wasn't for vcds it would be staying how it is. I've been watching vids of engines mistimed and they sound nothing like mine.
