    Head bolt part number

    Hey, does anyone know the part number for the 2x one chance head bolts? Inevitably I rounded both of mine, I had a look at an exploded diagram of the engine and I couldn't clearly see which bolt it was. The Honda parts guy couldn't see it either.
    Cheers

    Lol, I like that term. "Once chance head bolts". I'm about to pull my head off, so I'll be keeping an eye on this thread.

    Under the gear train there are 2 6 sided head bolts with very shallow heads. I thought I could get away with using a normal ratchet and a 6 sided deep impact socket, very wrong. You'll need a t-bar or something similar to apply downward pressure to the bolt as you undo it. Once the socket slips off the bolt head its a bitch to get the bolt out, make sure you use a 6 sided socket, anything else will shag the bolt head. good luck young Padawan, may the force be with you.
