As You May Know, The CX330 Is The Upgrade To The9050B Model From Case. The CX330 Is Quite An Upgrade,being Much Bigger Than The 9050B. In Standard Form, The CX330 Is Almost 5,000 Poundsheavier Than The 9050B. This Added Weight Comesfrom A Larger Counterweight And From A Redesignedcarbody That Will Now Completely Enclose The Swingsystem. These Added Pounds Will Also Contribute To The Boostin The CX330s Over-front Capacity, And In Combinationwith Higher Hydraulic Pressures The Travel Circuit,give The Excavator A Very Impressive 16 Boost In Draw Bar Pull, Which Means More Power For Negotiatingpoor Underfoot Conditions And Very Steep Grades.In Addition To The New Features, The CX330s Digginglinkage Has Been Enhanced In Many Ways. The Boomand Arm, Deeper In Cross Section To Accommodate Higher Digging Forces, Now Incorporate V-groovetype Welds That Are Placed By Robots And 100 Percentultra Sound Inspected.The Boom Foot And Boom To Arm Pivots Use Improvedbushings, New Plated Pins, And New Dust Seals Thatcombine To Make A More Durable And Easier To Takecare Of Assembly. The Newly Hardened Chrome Pinswill Also Contribute To The Overall Digging Linkagedurability.Even Though The Basic 6 Cylinder, 8.3 Liter Enginein The CX330 Has Been Used In Case Products Since 1985, Continual Refinement Over The Years Has Changed Nearly 85 Of The Original Engine's Partnumbers. The CX330 Features 259 Net HP With Anair To Air Intercooler And A Free Breathing 24 Valvecylinder Head. The Electronic Logic That Controls The New Engine'sfuel System Tracks The Machine's Operating Parametersand Keeps The System Continually Armed To Respondinstantly And Precisely To The Fuel Requirements Ofeach Individual Cylinder. The Total Electronic Design Of The Engine Will Also Eliminate Cableand Step Motor Controls From The Fuel System, Witha Large Gain In Reliability.Even Though Modest Changes In The CX330s Digginglinkage Geometry Will Contribute To The Higher Forces Of Digging, The Big Guns Here Are The Refinement Of The Trench With It's Open Centerhydraulic System. The Main Pressure In The Implement Circuit Is Up Almost 8, With The Hydrauliccylinder Diameter Up 7 As Well.Hydraulic PowerThe Increase In Hydraulic Power Combines With Themore Efficient Linkage Geometry To Yield Almost 20 More Bucket Digging Force And 15 More Armforce. With 19 More HP, The CX330 Can Drive It'smain Hydraulic Pumps With Much Better Force. Inaddition, The New Pumps Will Produce About 6 Moreflow For Increased Hydraulic Speed At Much Lowersystem Pressures.The New PCS (Pro Control System) Will Manage Thehydraulic System And Interface With The 6TAA-830engine, And Does It With More Electronic Geniousthan The 9050B Did. Similar To The 9050B, TheCX330 Does Have Manually Selected Working Modes,although It Departs From Previous Designs By Addinga New Automatic Work Mode. By Working In Thenew Automatic Mode, The CX330 Can Analyze Loaddemands And Operator Input At The Joystick, Thenadjust The Engine And Hydraulic Pumps To Balancepower And Speed With Efficiency And Even With Theeconomy.Other PCS Features Include A High Speed Assistancesystem, Which Will Speed Up Boom And Arm Functions,and An Automatic Power Boost System As Well. Thepower Boost System Will Increase Main Pressure By10 For 8 Seconds If The Implement System Reachesthe Standard Relief Pressure For More Than 1 Secondin Tough Digging Conditions.With Everything The CX330 From Case Offers, It's Truly The Best Excavtor In Years. Case Has Outdonethemselves This Time, Doing Their Part To Makeexcavating Both Fun And Exciting. If You've Beenlooking For The Perfect Upgrade From The 9050B, TheCX330 Is All That And A Bag Of Chips.PPPPP(word Count 630)
