Just done mine. 2 hours on Friday night taking it all apart, got stuck when I got to the Harmonic balancer bolt (noise issues in carport while kids were trying to sleep) started at 8 the next morning and was driving by 2.30. I found the hardest part was lining up the belt properly. Had to do it three times and it was a mongrel to fit as its so tight when its new but apart from that it is a straight forward job if you follow the Haymes book.
