My van is eating pulley wheels

Okay my van has started eating pulley wheels!

So pulley number one went a few weeks ago and was replaced  then another one went at the weekend!

Pulley number 1


Pulley number 2



So something must be going on to rip off the welds.

My only idea is that a horizontal force must be acting on the alternator shaft which causes the pulley to be forced backwards to the edge of the alternator.

The only thing that I can think is the bearing is overheating and allowing the movement.

So the bearings feel smooth and spin cleanly but suspect at high speed it heats up and give up.

So new alternator required. Went for Bosch orginal.

Decided  to take the engine out as it's quite hard to lift the fan housing out.




Engine and fan housing off.

Need to buy a 36mm socket to get the fan hub nut off.

More to follow
