I just pulled my fuel pump off my zd30 and I noticed that the timing marks on the cams don't match up to what the manual said, would there be a reason for this? and would this cause blow-by the motor was rebuilt in 5/12

Try rotating the crank and see if the A and the AA marks and the B and the BB marks move away from each other if you get what I mean. Count how many teeth apart they are and see of it changes when you rotate it .
If they do you can keep rotating it till the marks all line up to make sure all is well. I reckon it will be ok.
Do they line up if you turn it 180 degrees
I've turned it heaps and always comes back to 3 teeth out or heaps out could it be just a stuff up by mechanic
They will just be an odd number of teeth and require multiple rotations to line up.
I don't think a mechanic could get that wrong when the gears are clearly marked like that. It will take a shitload of rotations to get them to line up.Quote:

Just a thought, the cam gears are evenly spaced on the idler gear both 4 teeth and the idler gear only keeps them in time it shouldn't matter as long as they stay the same spacing ? And the timing chain didn't have any timing marks on it either maybe a old school mechanic using his brain? Still I am trying to call workshop to talk to mechanic anyway
Sorry guys it does take a thousand turns and eventually they all lined upQuote:

Update, after following the gregory service and repair manual I tried lining up the bottom end timing marks and found this dumb idler with some spring loaded set up and after searching the internet on how to line the marks up it has been brought to my attention that before removing fuel pump gear you need to take a plug out and lock the idler with a lock nut. I can't find anywhere in the manual where it says to do this
Is this what you are after?
yea that's it where do I find that info?
You can download the genuine workshop manual from this forum. Here's the link

You will need to have a post count of 25 to be able to download it. Just go and welcome some new members to get your post count up.

cheers mate
Can I reset the spring loaded thing myself or does it have to go to a specialist to set it ?
