tech help needed, crank ovality???
ok my son has got this question and its a bit beyond me so any help would be great. what is the magic formula to calculate the ovality of a crank???
this is the actual question...........
"list the measurements you made from the crankshaft of your engineand work out the ovality of the big end and main bearing journals."
now obviously i don't want the answer , just how to work it out. many thanks mick

you measure the crank jounal at 4 points, each separated by 45 degrees so you have 4 thinkness measurments, then after finding the smallest and largest measurments, the difference is the ovality of the particular journal.
this is how it was tought when i was studiying for my NVQ "motorsport vehicle maitanence and repair" course
