I-530E Engine Durability The 530E Redefines Mid-Range Durability Through Innovative Design To redefine legendary standards of mid-range durability, we looked beyond expectations. Using the latest in 3-D computer modeling technology, our engineers simulated engine operat- ing conditions. Then we determined where and how strategic gains in mater- ial weight would provide the 530E the strength it needs to thrive in demanding applications. The result? This engine's premium components are designed to work hard for you day after day, year after year. The International 530E adds miles 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 strategi- cally 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 regrindable. 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. 6. Two-Piece Forged Steel Crown Piston In 530E engines rated 300 hp and above, the center combustion bowl design and 8% longer steel piston pin distribute load and thermal stresses evenly for more efficient combustion, improved cold starting and longer life 7. Piston Cooling Jets Lower piston and ring temperatures result in lower thermal stresses and longer life.
