I-530E High Torque Engine Durability The 530E HT Redefines Mid-Range Durability Through Innovative Design To achieve "big bore' levels of durability, the 530E HT engine's designers broke through the barriers and limitations of performance. Using the latest in 3-D computer modeling technology our engineers simulated heavy-duty engine operating conditions. Then we determined where and how strategic gains in mater- ial weight would provide the 530E HT the strength it needs to thrive in a heavy-duty environment. 530E HT components are designed to maintain their weight advantage while working in harmony to create a maximum range of operating power. The result?
The International 530E HT adds miles and hours to the life of your vehicle and profit to the bottom line of your business. 1. Ductile Iron Rocker Arms Designed for matchless durability, increased diameter rocker shaft increases load-carrying capability. 2. Crankcase Fully skirted, cast iron. Computer modeling was used to strateg- ically strengthen and widen bulkheads and bearing caps, assuring even load distribution to extend life. 3. Crankshaft Forged steel and induction-hardened journals and fillets, fully re- grindable. Wider bearing surface areas distribute load efficiently and new crankshaft seals with dust eliminators 4.
"TEE-PEE" Design Connecting Rod "Big Bore" rod design incorporates angle split and wider bearings to reduce shock and stress for added life. 5. Piston Rings Premium keystone style, plasma coated top ring provides superior sealing even in harsh work environments, extending the life of the power cylinder. Intermediate ring and oil ring provide lower oil consumption, helping to extended maintenance intervals. Page No. 55 COPYRIGHT© 2011INTERNATIONAL TRUCK AND ENGINE CORP.
