Timing chain on Vauxhall 1.3cdti

[Aprisa]

I've just stripped and nearly finished rebuilding this on one of our Combo vans, I've done a lot of 1.7 cam belts and this has come as a bit of a shocker.
Why is it that they see fit to design a crank and Cam pulley arrangement that has no guide dowels or locking mechanism apart from the friction of the sprocket to mating surface?

Do they ever slip and cause havoc?

And how are you suppose to get hold of a tool to lock the crank? I made one as suggested but would prefer a robust well engineered solution.

Not done one of these but ni on all modern engine dont use a woodruff key anymore, the crank and cam are locked with tools and the pullys/wheels are done up fooking tight! they dont tend to come loose in practice.
for that engone this is the tool with instructions

I do a lot of stuff after consulting youtube, i save it on the tablet to take it into work then run it as i do the job, no mechanic knows it all the first time and youtube can be used as a haynes with benifits, although my partner is 70 and can't use the tablet be can watch and do (thankfully)

Cheers for that, I do have the tools that you link to but the haynes shows another tool used to lock the Crank Pulley Boss whilst undoing the bolt and it's this one I had to make.

Do you reckon the Flywheel locking pin on its own would stand the torque of tightening the bolt? The Cam locking tools are not so positive in their location so I would not trust them to resist too much torque application.

No, not in any way, i use a pully holder similar to the link provided
for non holed pully i have used a strap type oil filter wrench to hold the pully, really depends on the job/pully TBH, i oftem have to make a crank holder using an old starter motor toothed pully cut in half and welded to some angle iron, sometimes that meens tremoving the starter to get at the ring gear, sometimes just removing a dust plate will give the access then make the bracket for the toothed part to fit the application.
