    I'm a bit stuck and could use some help.....
    I've recently changed the cam belt on my Astra G Diesel (GM Engine). Now, all this went very smoothly except for the cam belt tensioning. To assist with this, by locking off the camshaft and not requiring 3 arms, I got a camshaft locking tool (e.g. http://www.pvrdirect.co.uk/productinfo.aspx?catref=69934) but i cannot for the life of me figure out how to fit it!!!!! I'm pretty good (ahhem!) with most things car related, but this has got me stumped! :eh
    Can anyone help me out??!

    I'm beginning to wonder if anyone has successfully used one of these tools!

    Hi there,

    I see what you mean - the link to the instructions pdf doesn't work (neither does the other link). I was just looking at a image somebody sent me - I zoomed right in and I can't see where it is supposed to insert to lock. There's got to be somewhere to insert it, like a hole that isn't revealed until you rotate the camshaft.

    I did see mention of info on the camshaft locking tool use in the Haynes manual if you have one of those you could see if there's any useful info there. Or maybe just contact Draper? Hey when you do figure it out maybe you could post a picture here so we could see how it is used.

    Cheers, Paul

    Well, I've consulted the Haynes manual to no avail. Every time I look in it i find more mistakes - the one I found this time was a reference to the timing belt tensioner which refers you to a picture. Unfortunately the picture they direct you to is of a piston!.
    So I've gone for contacting Draper. Hopefully they will be of more help!

    The only thing that did occur to me is that it may install where the vacumm pump is. Seems unlikely though.

    It goes inbetween the 2 sprockets at the top where by the looks of it. I bought a similar one which didn't look like it will fit, but after some wriggling etc it slotted straight into place.

    Only got 1 sprocket at the top on the X17DTL. Assuming you're talking about two cam shaft sprockets on a twin cam engine? X17DTL is single cam. Or have I misunderstood?

    Yeah I think Northstar is thinking of a twin cam and I've seen pictures of a similar locking tool inserted between the two.

    The one shown in your link is described as a single sprocket locking tool but as I mentioned above, looking at a picture of the sprocket area on my computer I can't see where it would insert. Surely that little bit that sticks out is supposed to slot into a hole somewhere.

    I reckon just contact Draper and ask for install info or ask PVRdirect if there ever was a link to a PDF file as hinted at on the link you provided above...

    Does this engine not have a locking tool that fits in the back of the head behind the vacumn pump

    Thats what nonmechwarrior was wondering in his post above, but it does look rather like the twin cam sprocket locking tool. I've never removed my vac pump so I don't know what's under there.

    Anyway, I figured it would be easiest (maybe) to get install info from Draper or PVRdirect...

    The description certainly says it's for the GM 1.7 diesel, which is only (I believe) available as a single cam.

    I put an online technical support enquiry into Draper this morning. They said they'd be in touch within 3 working days, so will have to wait and see. In the mean time I'll have a look if it will fit in lieu of the vacuum pump, this weekend.
