"seated" You should be able to easly  turn/spin the shims, with your finger, like a "rapper" does a when ruining a good record. (Dat's Vinyl to you youn-ons)   On Saturday, June 14, 2014 1:59 PM, "'Norm Keller' normkel32@... [DSN_KLR650]" DSN_KLR650@yahoogroups.com> wrote:
  IMO, the largest risk is in manipulating the cam caps. They often bind on the dowels such that one can feel as though it is seated but rather it is cocked. Make absolutely certain that the caps are seated to the head before tightening the bolts, otherwise you may distort or break a cap.   If you record the clearances and shims which are in each location before and after the adjustment/inspection, you will have a jump on the next time.   As for the shims needed- others have nailed that but will try to add some more thoughts: The clearances will become smaller because valve recession is the normal change in valve train. This means that the shim needed will be thinner than the one in place. * Note: If you discover that the valve clearance is larger than specified- STOP!   If clearance is larger than specified, you may have made a mistake; there is carbon/deposit build-up on the valves; bent valve; seizing valve guide; etc. These possibilities must be considered and qualified.   I also don't use the shim calculator- seems a waste of time to me but that's just me. Every "step" in valve shim number is 0.002" in thickness so I simply consider the amount of clearance change needed divided by 2  (0.002) which gives the number of "steps" in the valve shim ID number. If the shim in place is a 265 and 0.004" increase in clearance is needed, then that is 2 steps in shim number so 265, 260, 255.   Since I'm old and mentally defective (hope someone thinks this is a joke), I measure the replacement shim with a digital caliper, note the thickness, hit "Zero", then measure the original. The dimension shown on the caliper will be the difference in thickness which should match the 0.004" needed. I then close the caliper which should read the dimension of the original and do a quick calculation to insure that it matches the 0.004" needed.  Not a big deal if I'm wrong as will check the clearance with a feeler before buttoning up the cover.   Be careful not to use one bolt to pull the cam cap down. If you cannot get the cap to go down so that the cap is mating with the head surface, pull the cap and recheck. Sometimes they need a little "help" but don't, absolutely don't assume. If you've trapped some bit of debris which has fallen in, you can distort/break the cap, break a bolt and/or result in excessive cam bearing slack. If a cam cap is broken, the head is finished unless you have extra-ordinary intervention available.   Anyone in the Fraser Valley is more than welcome to a hand/advice in doing valve adjustment. I'll also try to help by direct email if that's useful. I'm retired and enjoy the challenge of remote servicing.   Norm #ygrps-yiv-1361086400 #ygrps-yiv-1361086400yiv3376912290 #ygrps-yiv-1361086400yiv3376912290 --
