Features
Serviceability		Entire unit is designed for ease of repair. All components are readily accessible.
Standardization		Many components are interchangeable throughout the various lines.
Full Pressure Lubrication		A frame-driven lube oil pump provides pressurized, cooled oil through a full flow oil filter to all moving parts in the frame. A divider block distribution system supplies metered oil to cylinder bores and rod packing. Stainless steel tubing is used throughout the cylinder lubrication system.
Unloading Devices		Manual, head-end variable volume clearance pockets, pneumatic fixed volume clearance pockets and pneumatic suction valve unloaders are available on a limited optional basis.
Heavy Duty Crankshaft		Forged steel, precision machined with integral counterweights.
Rugged Crankcase		Heavily ribbed (with spacer bars for stiffening), high strength cast iron base with removable lightweight, aluminum top cover and removable end covers for ease of access.
Precision Bearing Shells		Precision-machined, tri-metal main and connecting rod bearings.
Rugged Crossheads and Guides		Cast iron crosshead guides, external ribbing and removable side covers. One-piece, long life crossheads with direct full pressure lubrication at top and bottom for minimum wear. Hardened and ground steel crosshead pins.
Precision Bearing Shells		Precision-machined, tri-metal main and connecting rod bearings.
Rigid Connecting Rods		Forged steel four bolt, heavy duty "H" section
Quiet Auxiliary Drive		Fully enclosed and continuously lubricated chain drive adjusted by positive positioning eccentric vernier.
Oil and Dust Seal		Foolproof, non-contacting crankshaft oil seal plus reliable non-wearing dust seal.
Proven Cylinder Design		Non-cooled compressor cylinders with ample nozzles and large gas passages. Cylinder bodies are ion-nitride hardened and drilled for indicator ports.
High Strength Bolting		Grade 8 bolts or B-7 studs on all pressurized components. All bolting designed for accessibility.
Efficient Valving		Ariel uses plate-type valves designed for modern speeds utilizing non-metallic sealing elements as standard. Selected to adhere to established, low valve velocity standards.
Durable Pistons		Wear resistant ductile or gray iron. Available with wear bands.
Stout Piston Rods		Short, stiff, precision ground alloy steel piston rods with locking crosshead nut. Rolled threads are ¼" under rod diameter for easy installation through packing.
