Im trying to finish putting the engine back together and i cant remember how to measure ring end gap. The engine is a 93 lynx 340 fan cooled engine. Ray at associated crankshaft told me that the gap shouldnt be anymore then 12 thou. how do i measure this? also anything else i should know about putting the circlips in and rings? need help fast

use a piston to push the ring down into the bore a little. then measure the gap and file to get to desired spec.

Insert the ring from the top of the bore and use the top of the piston to push it into the cyl about 1/2" down, by using the top of the piston you are sure to get the ring square in the bore. Then take a feeler gauge set and find out which one fits. You will need a ring end gap tool to set it correctly. You can also use a points file too, break the sharp edges when you are done. Slight drag of the feeler gauge is what you are looking for the know the gap is set correctly.

thanks, i did some looking around on the net and figured it out. i went with .016 ring end gap to be safe and i have the whole top end together. i just need to put on the shrouding and intake and exhaust manifolds on. looking forward to fireing it up tommorw.
