Applicable engines and rebuild scope
This chapter applies to International DT466 and DT530 engines of the 2000-2003 range. It stresses that proper flywheel-housing bore concentricity and face runout protect engine-to-transmission alignment and transmission life, measured by attaching a dial indicator to the crankshaft and rotating it to record total indicator variation. For crankcase reconditioning it recommends a chemical bath or hot tank, cleaning the oil galleries and cross drillings with a nylon brush, sealing new main-gallery cup plugs with Loctite, and checking crankcase deck flatness with a straightedge and feeler gauge, noting the deck must not be resurfaced. Full engine and dealer support is available from the International Trucks website.
Who needs this DT466 DT530 crankshaft chapter
Rebuilders overhauling a DT466 or DT530 bottom end use this chapter for runout tolerances, crankcase cleaning steps and cup-plug sealing procedures. It is essential reference for anyone verifying flywheel-housing alignment before a transmission or clutch reinstall, and for measuring crankshaft flywheel-pilot concentricity so the driveline runs true after reassembly.
