|
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 |
Ductile Iron (JGH) or
Forged steel (JGE), precision machined with integral
counterweights. |
|
Rugged Crankcase |
Heavily ribbed high
strength cast iron base with spacer bars for stiffening,
removable end covers and lightweight aluminum top cover 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 |
|
Rigid Connecting Rods |
Forged steel four bolt,

dust seal. |
|
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 |
