You'd inspect the bearing and roller surface for obvious signs of wear visually, and for freedom of movement. You'd also check that the bearing cage is intact, and that the ball bearings are properly held in/spaced out by the cage.
You'd also inspect the surface of the cam plate for excess wear.
And finally, you'd pull/push in and out, left and right on the nut on the end of the timing device (visible when the pump is removed, right in the center of the cam plate). Anything but the slightest play can indicate the brass bushing that the shaft rides in is worn excessively.
It might not be practical to address problems found during this inspection, but at least the issue would then be known and could be addressed when the car can be put up for work again.
