C 10 valve adjust -- do-able without socket wrenches?
« on: October 14, 2017, 05:09:04 pm »
I'm about to delve into a C 10 valve adjustment. Just discovered my ratchets are at work, an hour and 15 round trip - a trip I've made waaaaay too many times, so,

Can I get it done without ratchets? Using just combination wrenches?

Thanks.

I think the most critical thing is getting out the spark plugs. Maybe if your Concours toolkit contains a spark plug wrench.

Answered my own question -- yes I need the sockets for torque time.

As "they" say - Oh well...

True - the plugs. Good point.

I'm kinda torque wrench friendly when it comes to aluminum, so yeah, a trip to work it is.

I forgot to stop at the cuss word store after I bought the RTV, so a head heli coil campaign is not possible today.  :)

Just remember that the torque value in the shop manuals for the valve nuts is wrong.  (I don't recall the right value, but it is supposed to be in/lbs, not ft/lbs like listed.)

18 ft/lbs is a bit heavy for those nuts.  I've been using 13 ft/lbs (156 in/lbs) with good results.  Interestingly enough, my '84 Honda Sabre had an almost identical valve setup and it's torque value was 17 ft/lbs (I believe, could have been 18 ft/lbs, also).  They even sold a special, 1 foot long, 10mm wrench for tightening them back up.

Thanks. I did those freehand.  I did make an audible "ka-tink" sound while I was doing it though.  :)

I did behave myself with the spark plugs and the valve cover bolts though. Turns out the valve cover bolts correct torque is pretty much snug until they stop -- ka tink.
