Very good video. On a different note. Is it possible if the tensioner belt disintegrates could some of the pieces enter under the two timing belt covers and cause the timing to hop out & bend a valve? Thanks.
Sounds to me like the camshaft pulley wasn't tightened enough that's why the belt is loose. I'm having the same problem but I can't get to the bottom of it. My belt still has the correct tension though
Not sure if same was driving mine yesterday at 30mph engine locked up and cut out wouldn't even turn over after took belt cover off belt not snapped I need to see if its jumped a tooth as mine now seems a little loose like this 1 really don't know what to do. ??? Manchester area
Hi something similar happened to mine and now the pullys are well out i put new belt on and timed it up using tools , could my crank be 180 degrees out many thanks for all your help
If the crank has spun on the keyway it could be out by any amount easiest way to check removes cylinder one glowplug and verify cylinder at top dead center
When did you figure out that was the pump you were pointing at saying this faulty tensioner may be to blame 😂 tensioner as you may now know is below the pump slightly to the left
I will like to know it too. I have a A20DTH and the timing belt broke. Now I will have to do a valve job but I will like to know how to reset the timing. By any chance there is a place where I could get the repair manual?
@@salvadorsierra7153 for the cam pulley you lock it through the plug in the rocker cover. The bottom pulley has a timing mark on the casting and pulley and the fuel pump has a hole for a pin to lock it.
You’re wrong about the timing marks. The purpose of pinion marks is for the timing Belt alignment, to keep the corect syncronisation of HP Fuel pump. There are no idication of pinion marks to line up with Any other case marks. I have very much experience with this engine and the correct orientation of the pinion marks should be : -9 o’clock for the crankshaft pinion -2 o’clock for the camshaft pinion -11 o’clock for the HP fuel pump But even with this method or using timing tools you can be very wrong if the crankshaft pinion has the inner pin damaged and the pinion is twisted around the crankshaft. For 100% safety you should check that pinion, or check the cylinder 1 TDC trough the injector port.
@@simonmackie8258 it's not so much timing but more "phasing" - you want the pistons in the pump to be whacked close to injector opening so the pressure flows rather than backs up. EDIT: As Alex stated, you time these up without tools just using the marks on the new belt. White lines that you line up with the notches in all three pullies. It's the quickest and easiest way to do it and is literally fool proof.
