i'm halfway through (well 1/8th of the way!!!!) changing my stem seals and just had a quick question. In the haynes manual it says and shows 5 parts that hold the cam in place, however in mine there are only 4. Just thought it was a bit weird, almost looks as tho one of the supports isnt there. Anyway the question is which will be the best way to tighten the cam back down once the jobs been done? I think the book says 5,3,1 and then 2 and 4. Its looks like i dont have a number 4. confused (doesnt take much i know!)
