Features

• Meets EPA and CARB emissions requirements for 2006

• Single piece design for outstanding structural rigidity

• Mechanical Electronic Unit Injection (MEUI) and ADEM A4

allows variable injection timing and controls the quantity
of fuel

• Twin wastegate turbochargers provide higher boost over a

wider range that will improve engine response, outstanding
low end performance and improved peak torque

• Forged steel design piston provides higher strength, lighter

weight, better oil control, and less liner wear

• Cylinder liners are hardened plateau honed to reduce wear,

reduce blow-by and improve oil control and consumption

• Leak free design by improving joints throughout the

engine and all fluid connections using the standard
thread ‘O’ ring design

roller bearings.

Features

• Splash lubricated and sealed with Duo-Cone

®

floating

ring seals

• Sprockets have five bolt-on, replaceable rim segments

with more bolts to resist high impact loads

• Eliminate ground and implement induced impact loads

for extended power train life

• Abrasion-resistant steel increases sprocket segment

wear life
