Chain Rammer parts diagram: 1 rammer chain, 2 servo motor, 3 helical gear pair. 26 parts in 3 top-level items. — Chain Rammer 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	Rammer Chain	1×	Push-pull rigid chain
2	Servo Motor 4 parts	1×	Brushless motor with an integrated encoder or resolver, driven in closed loop to hold commanded position, speed, or torque precisely.
3	Helical Gear Pair	1×	Two meshing helical gears forming one reduction stage that steps torque up and speed down between parallel shafts with quiet, continuous tooth contact.
