Chinese Timing Tools

[dai1983]

Evening,

My 2.5 v6 needs a timing belt as is never had it done at nearly 80k! Anyone have experience of these cheaper tool kits?

I do all my own work and have done a couple of floating pulley Fords and Renaults.

You do not need any tools for setting the cam timing.
If you note the timing marks on the rear pulleys in "safe" position, that is where the factory set it, that is where it must be with the new belts fitted.
Simple. And if you have never changed belts before it will be the factory setting!

The front pulley is just a driving pulley the cam timing setting is determined by the two sets of rear pulleys. Take a pick of the marks before you start the work and let us see.

There is no need to disturb the front pulley at all.

Cheers for the reply,

Is the crank pulley keyed then?

That is Kaiser's opinion on the timing tools, and he is more than welcome to give it.

The alternative view is that the only way to ensure the timing is correct is to use the timing tools - you should be in the ball park if mark everything up though.

The discussion on whether to use the tools or not has been done to death on here and elsewhere, so we might as well agree to disagree.

It isn't just a Rover thing - did a cambelt on a Citroen DW8 last night, and both the cam and fuel pump sprockets float so you pin the flywheel, cam and pump sprockets, tension the new belt and then lock up the sprockets.

The good thing about the DW8 timing pins is that you can knock them up yourself.

A view to which I subscribe - that the only way to do it properly is to use timing tools. I will be doing the belts on our Ecotec 1.8VVT soon and despite being a much simpler set-up compared with the KV6, I will be using timing tool set.

Have to agree with this.
I've done several & always use the tools & use new sprocket bolts too.

The two rear pulleys each bank are keyed and marked, and so is the crank pulley.

Yes they are all keyed, but the front two cam sprockets float.

So what?
1.They don't if you leave them!
2.The timing marks are on the rear! That is where the timing takes place.
3. If the fronts have never been moved, the timing is factory set and there can be no doubt about the setting! It must just be reproduced after belt change. Like on any normal car!

Is this really so difficult to understand?

Hello David. I don't have any experience of the kit to which you've linked but I see that it's unbranded with no warranty, made in China and retails at £55. Deduct the seller's profit and what tool quality do you think you'll be left with?
