Compressor Block parts diagram: 1 crankcase, 2 crankshaft, 3 stage cylinder, 4 piston set, 5 stage valve set, 6 intercooler coil, 7 intake filter, 8 ball bearing, 9 oil seal. 21 parts in 9 top-level items. — Compressor Block 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	Crankcase	1×	Aluminum casting carrying the crankshaft and splash or pumped lubrication for the running gear.
2	Crankshaft	1×	Counterweighted shaft with offset throws driving all four pistons, belt-driven at about 1200–1500 rpm.
3	Stage Cylinder	4×	Stages 1–4, decreasing bore
4	Piston Set	4×	Ringed piston for low stages; the final stage uses a clearance-fit floating piston without rings.
5	Stage Valve Set	4×	Reed/plate valves per stage
6	Intercooler Coil	3×	Between stages
7	Intake Filter	1×	Dry cartridge filter on the intake, fed by a snorkel placed clear of any engine exhaust.
8	Ball Bearing	2×	Crankshaft mains
9	Oil Seal	1×	Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
