Title: Timing belt alignment marks
Post by: v6coop on 20 July 2008, 18:33:54
Still trying to put the car back together after head gasket replacememt.

Going OK, just a lot slower than I anticipated (did I really need to strip the heads!). I got a new timing belt from Vx at trade club price (Part No. 9128500) as I am fitting it everything goes well on bank 1

(http://i285.photobucket.com/albums/ll62/jonlew5/IMG_1284.jpg)

but bank 2 the marks are nowhere near

(http://i285.photobucket.com/albums/ll62/jonlew5/IMG_1286.jpg)

First of all I think it must be the wrong belt so I count the number of teeth and it's the same number as the Gates I have just takken off. It is fitted the right way round so thats not the problem. Whats wrong?

To add more fuel to the fire I could just make out the timing marks on the Gates belt so I thought well I will just count the number of teeth from the crank mark to sprocket 1 and 2 marks and then on to the  sprocket 3 and 4 marks. Then I find there is one more tooth to the first timing mark on the gates belt than Vx! You can see a white dot on the belt with tippex where I have put the corresponding Gates marks. What's going on?

On the Belt there should be a single line that you start with at the crank, use a mirror to get it right then put the wedge in to hold in place,the lines should then line up.... I have noticed as soon as you tighten the tensioners then turn the crank loads of times to check that the lines don't line up again....
Having said that there was belts that didn't have any lines at all on, so I have seen people using the old belt to copy over the lines to the new one.

Many belts have 2 different coloured lines to deal with different configs.

New belts often come with no markings, therefore it is OK to ignore the lines as long as you fit the belt correctly.

I'm sure you mean a double line ;)

The alignment in the photographs are with the crank mark spot on. Are telling me that a Vx belt won't have the timing marks for all 4 sprockets on the belt? It only has 4 marks plus the double line for the crank on so no multiple markings even in different colours. Can someone check the part number for me and see if this is the right one please? If I don't have any marks for sprockets 3 and 4 how can I know that it's fitted correctly? I am at friends for dinner (wife said she would divorce me if I stayed at home working on the car  ::) so not able to get on line as easily as I would like so appologies if I cannot respond immediately.

Unusual to find a Vx belt nowadays with any markings at all...

Well I am looking in Vx Trade Club Book and there are two Cambelts here:
2.5/2.6/3.0/3.2 to ENG 08144299 - Part number 90500360
2.5/2.6/3.0/3.2 from ENG 08144300 - Part number 9128500

As Jaime said really as long as you have fitted it correctly and tensioned it correctly and when you have tuened the crank a number of times to make sure the cams are in time you should be ok, as said before alot of the cambelts did not have marks on at all.

He'll be using the same yellow book I have here Nursie.
It's a gift from a secret society we both belong too.
Bit like the masons but without the rolled up trouser leg and baring the nipple (we had to do away with that bit cos Daz was getting over excited).  ;D ;D

Seriously though if you get a genuine Vauxhall Trade card they send you a book with all the trade club prices in and access to the same on the trade club website.

I could probably call in after work and pop the belt on for you.

Mark

Thanks for the offer. I have had my head down all day finishing it off. Managed to time the belt up OK after playing around with the adjustments a few times. Had real probelmes getting the nearside exhaust downpipe back onto the manifold but managed it after some serious persuasion. Was a bit woried when I started it up and there was an awful rattle from the 1-3-5 bank. I asume it was the hydraulic lifters as it all quitened down after a few minutes. Took it for a drive and got the engine management light but discovered the connector in the back right hand corner of the plenum chamber had popped off so soon sorted. No sign of anything leaking yet, so far so good.  i will run the valve spring compressor and valve seal pliers back one evening. Any preference for you?
