How to measure a cylinder.wmv

Three ways to measure a cylinder.

[@hoganhopper1978]

good info. I had to refresh. it's been since 1982 that I had to acually check bores in a cylinder. not only that I got the bore gauge and was sitting here and telling myself" how was it I check the bore with the gauge" thanks for the refresher

Good vid. Thanks for making a somewhat confusing process easy to understand.

thanks. very informative. attempting doing first re-ringing on an old triumph.

This really helped me out. I guess if you build to spec and clearance for piston/ rings are out of spec u need to take back to machine shop where bore was done?

[@bigfoot5ful]

this helped alot thanks ken

Seems like the ridge at the top would mess up getting a good reading with that digital caliper unless its edges were able to get below it

if you want a precise measurement, make sure the temperature is 20 °C

hey dude how balancing single crank shaft perfectly

[@mrblonde108]

50 over with .004" clearance????? i don't see any 50 over on paper. unlless u mean .25mmx2? How did u get .5mm over??? Could u explain your measurments? it would be clearer if u stuck to mm or inches instead of going back and forth. sorry i'm slow.

so if the machine shop bores my cylinder to 68.5mm, i need a 68.5mm piston since piston clearance is already considered when the piston is made?

[@jdmfans6078]

JOESLIM you will need a small piston other wise will scrape the cylinder walls.

[@mrblonde108]

the piston is 68.25mm and the bore is 2.619 (65.475mm)then you say piston is too small ..... ??????

My god do not tell these people to use a CALIPER to measure the bore! You CAN NOT get an accurate measurement with a caliper since the wear is below the top of the cylinder. You have to measure from a few inches down the bore. The piston rings never contact the very top of the cylinder so it should always be a factory spec and never have wear which will tell people that their piston to cylinder spec is was tighter than it actually is.

Stop this stupid inch stuff.
