You obviously did not get the cause of the problem. Something is tightening up causing the belt to wear.

So you just chaged the belt without checking to see why it had failed.
You can't blame the P38 for your errors.

Just gone through a very similar experience. Firstly heavy steering closely followed by the battery light and then the oil light - panic. I thought the belt must have gone but it was still there and tight. It was only when I fired the engine up and looked - the belt wasn't going round. The crankshaft pulley nut had come loose, the pulley wobbled about and had sheared the woodruff key. The oil pump is just behind the pulley and the drive was affected. Fortunately the good oil and regular changes have protected the bottom end and there's no damage apparent (yet). I can vouch that new genuine pulley's are expensive - make sure your front nut is tight next time you're near there.

Crank bolt should never come loose on a diesel, it is angle tightened to a serious degree. Just tightening with a bar is not good enough, the oil pump drive is nipped between the crank pulley and the crankshaft. Not tight enough you lose the oil pump.

Chaps.

Firstly gotta apologise for the useless post.
Was just fed up.
Love my P38.

Very busy in work at the moment.
So my friend, who is a mech is going to fix this one for me.
The power steering pump is where my money is.

Hate to hand it to someone else, but there is nothing to be done.
Just no time at the moment.

Hopefully we'll be up the mountains again soon.
I'll let ye know the outcome.

Okay update from my friend.

The belt tensioner, has failed and is not keeping the belt tight, hence the warning lights smoke and heavy steering, guess it didn't like being disturbed.

The original noises, were caused by the static idler pulley, the one near the alternator, the bearing has failed, and is very noisy. So good news.

Think Bix called it.

Well the Rangie is having the last laugh.

Changed the tensioner, and idler pulley, things were pretty much the same. Although the bearing in the idler pulley was shot.

Whilst, getting someone to turn the power steering, the steering pulley would stall. So it's a new steering pump at least.
Then having just one last look, it's not just the power steering pulley that is stopping, everything is stopping including the crank pulley.

So the original, name of this thread was correct, but at least it's a definitive diagnosis.

So if your steering goes heavy, and your battery light blinks when turning, check your crank pulley is turning. Oh the engine temp was a little higher too.

Who would a thunk it
Not looking foreward to getting that pulley off.
Rangie is back in the garage having a good snigger to itself.

I'll post up the conclusion to this problem.

It was indeed the crank pulley that failed.
The rubber damper was breaking up, debonding and rebonding with the heat.
It was probably the cause of my engine shaking issues from months ago.

I was advised not to get a spurious pulley, and got an oem one from Land Rover. the pulley as supplied does not include the centre mount with the keyway. This has to be pressed out of the old one, and pressed into the new part. A lot of force was required from a press.

The pulley was quite expensive at over 500 Euro (455 Stg).
Well worth though and the Rangie is fighting fit again.
