cam chain & sprockets?

[Landlubber]

We are all wise after the event, but next time......always put the r/h cylinder on tdc before playing with timimgs.

Then pull off the covers and observe the position of the various sprockets, marking the 6 and 12 position as mentioned above, also, do the timing (ignition sorry) bean can too, mark it so that it can be replaced exactly as it was removed.

I have an old barnyard R65LS that I will be playing with when I get home (I work in China), so I too will have to do what I say above. I have had many BM's in the past, you really have to think ahead on almost anything that you do with them, certainly they are simple to work on, but they are not simple to do many jobs unless you follow a few basic engineering principles. Pics before and after with todays digital cameras a re great.

Okay, Okay, Okay. It was no biggie.

Twirled the cam gear to put the "dot" at noon. Used a 6mm Allen wrench to roll the crank to TDC, or rather OT as the manuals say.

Put fresh batteries in my official R65.org flashlight and laid down up close and personal with the crankshaft gear sprocket. Upon closer inspection, what I originally thought was random scratches from a prior owner or shop service turned out to be a few extra scratch awl marks indicating the 6 o'clock position of the crank gear.

Now the question begs... Why isn't this simple chore mentioned in any of the BMW tech/repair manuals? Must be a conspiracy to market more high dollar BMW "special" tools or add to the imagined mystic legendary skills of a few BMW techs.

They probably thought, it's such a simple straight forward procedure, why waste time explaining it !!!

Kind of like an over haul manual giving detailed instructions on dis assembling an engine, and then one short sentence on how to re-assemble it, "Reverse dis-assembly procedure' .
