Thread: help please with setting TD5 timing.

I haven't done it yet but to me the first thing to do is rotate the crank until you get the pin in the hole in the flywheel.

You may have let the timing chain slip when you had the head off, so the marked links may be out of position.

Once you have TDC on the crank you can then set the camshaft to be in a position using the slots in the timing gear.

Now if you have let the timing chain rotate with the head off you have another problem. I have not tried it as I said but to me maybe you should let the tensioner go and then rotate the chain on the crank until it is in the correct position.
I don't know if you could do that without removing the sump.

I don't think it is important to have the timing chain links in the correct position as long as you know TDC on crank and can then pin the cam somewhere in the slot travel of the timing gear,ie you can place the timing gear into the chain in a position that you can then have enough travel in the slots to pin the camshaft..

OK. got my Wife to turn the crank nut and got the pin in the gearbox.then came up and only had to move the cam a smidgen (teck talk) and the top pin went in.
I am assuming it is now on TDC . Could I be wrong?I was thinking of removing the No 1 injector to check TDC in the morning after the mossies have moved on.
Do I need to do this or do I just locktite the three 13 mm bolds and call it done? ( I will also rotate the motor by hand after checking the injector clearances too).

Hi Nick
If you have both pins in then no need to go any further with that.
What you need to make sure of is that there is no slack in the chain on the left hand side of the engine ( the opposite side from the tensioner) while the pins are still in place. So while the 3 bolts are loose turn the cam sprocket by hand anti clockwise ,then nip up the bolts , torque them up to spec , then turn crank by hand through 720? (2 turns)
Obviously with pins removed, you should then have crank/cam in exactly the same position
Cheers

thats how i do it. just remember that the chain is a walking chain and the marked links are only there for a quide to enable smarty pants grease monkies to manage it with some extra attention to detail and a drill bit. If you have the crank locked and the cam locked the position of the marked links is virtually irrelevent.

of course it makes live harder for smartie pants grease monkies if you dont set it right in the beginning.

Thank you all very much; you guys really ROCK.

Great result mate.

in a TD5 (and pretty much every glow plug equipped diesel after the ones that had the glow plugs in the precombustion chambers) you dont pull the injector to check piston position, you pull the glow plug.

Did this solve the low power issue?
