Missed something while tearing my engine down. I didn't mark the cam gears before removing them, then found they have 3 keyways and the shafts have 1 key. My service manual has nothing about which keyway to use. I have cleaned the gears and looked in the keyways but could see no marks left by the keys. Is there an easy way to determine which position to set the cam gears?

I did exactly the same thing :-x What I was told to do was to set the crank to TDC, line the camshafts up approx 45 away from the barrels ( before opening for inlet, after opening for exhaust ) and line the timing marks on the cogs up as per the manual. There should then be a keyway in approx the right position to lock the camshaft. Mark that one & fit woodruff key & cog. It worked for me, but it's something I don't think I'll forget again. Many thanks to Ewan of Cosmos' classics for his help on that one :chug:

Thanks hobbit. It's going back togather as soon as I can order the gaskets & seals. It's not a bad engine to work on, just a little different than what I am use to.

Jtrip, there will always be a timing mark alligned to a keyway, maybe a dot or long/short dash or letter. Use this keyway to fit to the cam shaft.

No problen, there is a timing mark on the gear. if you hold the gear so the timing mark is up there will be a keyway that is also up. this is the keyway to use. this applys to both cams.the "long and short dash " is on the idler gear and is not a concern as far as replacing the cam gear, but just for the record these two marks align with the intake cam and are used to either set the intake cam in a standard "tiger' setting or a "bonnieville" setting. Advanced is "bonnieville" retarded is "tiger" check the rotation of the parts and engage the mark desired. have fun.
