Their are 2- 10mm bolts inside the head - under the intake cam - That require torqueing. Easy to access from above - thru the frame. However! As I removed the 1/4" socket (on a long extension) it got caught on something? and - There it was - GONE. It's a gut wrenching sound - to hear that socket make it's way into the bowels of your newly assembled top-end !
Not knowing where it went I decided to slowly turn the engine over (by the alt. bolt). Things stopped after a few degrees of rotation. After an extensive repertoire of the most colorful language I could muster, I set about the intended retrieval. Bore scope? Couldn't find that socket. Ever try to fish a magnet into a ferrous cavity !
Undaunted, I attached a tiny but strong magnet to the end of a piece of stove-pipe wire and started it's journey into the abyss. After several attempts I managed to get that magnet down along the cam-chain until it stopped. First removal - the magnet was still alone. Second plunge 'til it stopped and a careful extraction and I was almost in tears of joy when the socket came into view. The socket had come off and rolled down the chain; becoming trapped between the Cam-chain and it's secondary shaft sprocket. The socket does secure itself to the extension - until I cock it a bit. Then the locking ball becomes far less affective and............ Note to self.: Tape the socket to the extension OR: Buy extensions with an actual Collet-lock !
On to "dowel-pins." No trauma here but another caution along the same theme. I've had the cam-caps off numerous times over the years and this rebuild has raised another similar concern.
One of the dowel-pins wants to stay in the cyl.-head. It is removed easily and I found that most of them in the cam-caps, also come out easily ! I prefer not to Loctite them. No need to elaborate - just be aware !
If you have a dowel-pin that is difficult to remove I found that a 1/4-28 (or similar) TAP, will turn in a few threads and pull these pins. Pliers will deform and gouge if too much pressure is applied.
