Ovality of an AE crank pin refers to the deviation of the pin's shape from a perfect circle, indicating that it is elliptical rather than uniformly round. This condition can lead to uneven wear, increased friction, and potential failure in the engine's performance. Maintaining proper roundness is crucial for ensuring smooth operation and longevity of the engine components. Measuring ovality typically involves precision instruments to assess the extent of the deviation.

it is the product of the crank pin effort (Ft) and the crank radius (r).it is denoted by T.T = Ft * rT = Fp * r (sin θ + sin 2θ / 2n)
Ovality and Taper Guages are used
behind the window crank handle, there is a horseshoe shaped pin, pop that pin off and the crank handle should pull right off.

A crank pin is a crucial component in an internal combustion engine or a crankshaft mechanism, acting as the pivot point for the connecting rod. It converts the linear motion of the piston into rotational motion of the crankshaft, facilitating the engine's power cycle. By allowing the connecting rod to pivot around it, the crank pin helps maintain the mechanical efficiency and smooth operation of the engine. Proper lubrication and alignment of the crank pin are essential to minimize wear and ensure optimal performance.
With reference to the engine manf. tolerances and record sheet, using a calibrated micrometer. Bottom end bearing is removed from crankpin / piston removed. Surface wiped clean. Then at the specified points in the record sheet, measure the diameter. Normally at least 0, 45, 90, 135 deg. with ref to TDC and 5 equal distance locations across the pin. Normally wear would be seen at the top (highest loaded point), and may require grinding undersize to remove ovality, followed by thorough oil flushing / locate source of contamination. Check piston rings, skirt and liner condition for wear / abnormalities
I believe a gudgeon pin is what the British call a connecting rod pin (or wrist pin or piston pin) in a reciprocating assembly, (piston, connecting rod, crank ) It connects the piston head to the connecting rod.

you can buy a window crank removal tool at an autoparts store that pulls the little pin off to remove it.
Pin 1 is +5V, pin 2 is Ground and pin 3 is the signal. Use analog voltimeter in pin 2 and 3. Crank the engine: the pointer of the voltimeter shoud oscilate in range 0V to 5V.
