Hi
I'm new here and retired with part time job @ Toyota in pre delivery section Busselton.
I have the above Range Rover 2.2 diesel td4, which recently dropped the timimg belt by, I suspect, one cog as was running but noisy at top end.
it did this ticking over on my drive and when stopped would not turn over, I only tried the once and realised it is possibly one of the valves touching one of the pistons.
So i have done everything by the manual to replace the belt and I'm at the stage to fit new belt, I have aligned the top pulley for the rubber drive belt and have the exhaust side of the top cover to access the tappets for indication purposes.
When accessing the fly wheel and trying to locate the pin I managed to see the location hole for the tool to be inserted all good, so then fitted new belt and new belt tensioner kit.
I then proceeded to turn the engine in the clockwise direction to check for 360 degrees turning free. however it stopped with the number 1 and 2 pistons virtually @ top dead,if I then back around the opposite direction it does the same.
this to me is indicating the timing is out, I have since re-removed the belt and tried to establish the pin oft the pulley on the cmashaft for the valves.
but can't check whether I have the correct hole on the flywheel IE the manual says there are 2 holes and the large one is the correct one.
So my question to anybody who can help is if turning the engine via the crank to see the whole I would have to revolve it to top dead centre of piston N0 1 as this is the one the sensor sees to fire the injectors, by the way my injectors are all out. and using a welding rod to determine postion.
I suspect the cam has to be locked in the location point but this will leave atleast one of the pistons touching the valve which is starting to open.
can someone advise on the correct procedure to align now the actual belt is off because you are supposed to lock this all down before removing the old belt then replace with new as timing is still correct, however my belt was out in the first place.
Oh and I can turn the overhead cams with all the pistons at midpoint quite freely so i don't think any are bent.
Can anyone help please?
thankyou
