Roll Gap Adjustment parts diagram: 1 engagement lever, 2 micro-adjust handwheel, 3 eccentric shaft, 4 pneumatic engage cylinder, 5 gap adjust screw, 6 coil spring. 13 parts in 6 top-level items. — Roll Gap Adjustment parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Engagement Lever	1×	Hand or pneumatic lever that swings the slow roll into and out of contact with the fast roll.
2	Micro-Adjust Handwheel 3 parts	1×	Fine handwheel that trims the gap in steps of a few microns per division.
3	Eccentric Shaft	1×	Offset shaft that swings the slow-roll bearing blocks to engage or disengage the nip.
4	Pneumatic Engage Cylinder 4 parts	1×	Air cylinder that engages the rolls when grain is present and parts them when feed stops.
5	Gap Adjust Screw	2×	Coarse screw that sets the slow-roll stop position before fine adjustment.
6	Coil Spring	2×	Helical spring of round steel wire that stores energy in compression or extension, used for suspension, return force, and preload.
