1. A sieve assembly for use in an agricultural harvester, the sieve assembly comprising:
a cleaning shoe including a pair of opposed side rails; and
a sieve which is removably installed within the cleaning shoe at a selected location against the side rails, wherein the sieve has a downstream end and an upstream end, the upstream end defining at least one first non-zero angled surface, the downstream end defining at least one second angled surface,
wherein the cleaning shoe includes at least one first engagement surface for engaging the at least one first angled surface at the upstream end of the sieve, and the cleaning shoe including a pair of bolts, each of the bolts being pivotally attached relative to a respective one of the side rails and engageable with a respective second angled surface, each of the bolts having a longitudinal axis that is positioned at an acute angle (β) relative to the side rails of the cleaning shoe and biasing the at least one first angled surface into engagement with the at least one first engagement surface when the bolts are tightened against the respective second angled surface.
