not sure how I missed your message..notifications used to pop up when I logged on..this one didn't...Mcgeorge1972 has posted pdfs of most s81 repair manual sections..I suggest downloading them all..I don't think yo can post a pdf that large anymore ,but they are still downloadable.....look up his member name and then select" find all posts by" he only posted a few dozen in total so finding the manual sections is easy...
