Hi,
This is my first post in Pradopoint :-) I bought a 2004 Prado (Landcruiser LC4 in Scotland) last month and I'm catching up on some of the maintenance points. I used a guide from PP to change my timing belt and it was excellent, literally a 1hr job. I'm now having a little trouble with my v-belt / serpentine belt being 'eaten' by misaligned pullys (I suspect).
I replaced the old belt, ensuring that all the ribs (7 ribs total) lined up well on the PH, CC, AL, CK & WP. I notice that the old belt was badly worn and was very thin, it had only 6 ribs and the other was missing. I'm guessing that this has been worn away just like the new belt I put on (its only taken 3days to wear away 1 rib)!
When I look into the engine bay, it is clear that the serpentine belt comes of the altinator (AL) and feeds onto the first idler pully (IP) but doesn't align properly on it, it sits too far forwad. See point 1 in the picture below. The belt then feed incorrectly onto the CC and sits on the lip / edge of the pully. See position 2 in the picture below. The lip / edge of the CC pully effectively eats / wears the 7th rib off the belt leaving only 6ribs and a thin belt.
I thought the problem might be caused by the first IP, at position 1 in the picture, having a worn bearing and is 'leaning' forward or possibly that the alternator is too far forward.
Has anyone had experience of this? Can the alternator position be adjusted? Should I replace the IP?
Any help would be great.
