Have you checked the flywheel locking tool fits the opening above the starter?

You shouldn't require a puller for the crank pulley as it's only held in place by the crankshaft bolt.

Every step has been a hassle so far, locking tool needed grinding down to fit(but reading other posts that's not uncommon). Pulley definately isn't budging without a puller on it either

That's surprising - my pulley just slid off once I had the bolt out. There's no woodruffe key or anything holding it there - perhaps yours has rusted in place? Have you tried giving it a few sharp taps with a hammer (nothing too extreme obviously)?

I had to grind down my tool as well - I suspect it had been machined to the exact diameter of the hole, rather than to a dimension that would actually fit in the hole. I ground about 0.5mm of the entire radius and it was still a snug fit.

The pulley is a face fit almost, you have undone the large bolt in the centre and not just the 6 around the outside Question

The pins are made to fit the hole and then there is normally some sort of plating added that makes the pin oversize.

Th can feel the pain - for every good story there is a hard yakka story. Typical Landrover crappy design work - why design it so the starter needs to come out to get the pin in - same a a L series Freelander - the crank pin was impossible to get in without dismantling halfthe stuff around it.

I would be happy to do the belt myself but with having to take the starter out to also do the oil pump I think it is simpler to just pay someone - more expensive yes - but a lot less grief and stress.

Yep, main bolt is out - that was about the only thing that's gone right Laughing couple of 500mm pry bars won't budge the pulley. And today hasn't gone to plan either, I had to shoot down to a land rover dealer for an alternator belt as mine was looking very average - that's an hours drive each way, not dramas, but e. issus decided she wanted to go for a drive so that means we end up having lunch while out(and two kids in tow Rolling Eyes ), don't get home until 2pm and then it's not worth getting into the work as I need to go pick the other two kids up from school. Then there's sport training this afternoon so I just have no time to get into it until 7pm so I'll end up working until midnight getting this Censored done. There I've had my Big Cry I'm good now

Puller got it off. I think mine must be an exceptionally tight fit, even when all cleaned out when putting it back on it was firm. Once that pulley was of things started to go ok. Even managed to get the starter back in place in around 15mins Laughing On
Y had one hiccup once I finished when I attempted to start it. Made a horrible noise and then died. I forgot to bleed the air from the fuel system as I'd replaced the fuel filter while I was at it

Many thanks to Disco Mikey for this excellent article. Some tips on the starter motor removal: Disconnect battery and remove alternator. Jack up the car and remove the front right wheel. Unbolt fuel cooler and tuck it away above its bracket. Now remove V+ supply cable from starter motor whilst the starter motor is still mounted. Get this cable out of the way. Now you can remove both bolts holding the starter motor and simply slide it out. Quite easy to remove actually. Remove the 8mm nut and release the actuator cable. Then remove the starter motor down the opening in the chassis. Mine's a 2007 TDV6 with automatic transmission.

Can you get the parts through the forum?

New to this but encouraged by the advice, inspired by Disco Mikey - So now need the parts. Is there a way of getting discounted LR parts through the Forum?

Thanks

After changing the timing belt, is there a way to check the actual timing with a computer?
If so, what values are acceptable and unacceptable

Timing cannot be checked by computer. It is purely mechanical Thumbs Up

Thanks Mike for your reply!

All those sensors and not one for timing?!

I don't know too much, but I thought that there might be sensors on the cams or crank that could double check if the timing was ok after a timing belt change

How would you adjust the timing - say if you wanted to modify the way your engine runs for any reason - e.g. for motorsports, or running on slightly different fuels etc

As long as the cam and crank sensors are sync'd during start up, the engine doesn't care about heir relative positions Thumbs Up

Started doing the front belts today, but when it came to fitting the two smaller timing pins, only the left hand side pin would fit in. It fits in very snugly, but the right hand pin wont locate... have closed the bonnet and left it till tomorrow for the second try Big Cry Any advice greatly appreciated...
 what is this life, if full of care?
