E13C Flywheel Assembly 13450-E0G70 — Hino 700 Series Heavy-Duty Truck

This E13C flywheel assembly (OEM part numbers 13450-E0G70 / 13450E0G70 / S1345-03711) is a direct replacement for the Hino 700 Series heavy-duty trucks equipped with the E13C diesel engine. The flywheel is a critical rotating mass component mounted on the rear of the crankshaft that serves multiple functions: it stores rotational kinetic energy to smooth out engine power pulses between combustion strokes, provides the friction surface for the clutch disc to engage and transmit torque to the transmission, and carries the starter ring gear that the starter motor engages to crank the engine. A flywheel with a warped friction surface causes clutch chatter and uneven engagement; a worn or chipped ring gear results in grinding during starting; and a cracked flywheel is a catastrophic failure risk that can destroy the bellhousing and clutch assembly.

Manufactured from high-grade cast iron or forged steel with precision-machined friction surfaces, this flywheel assembly meets all OE dimensional and balance specifications for the E13C engine. The clutch friction face is ground to a flatness tolerance of less than 0.05mm to ensure complete clutch disc contact and smooth engagement without hot spots or judder. The starter ring gear is heat-treated, press-fitted, and precision-welded onto the flywheel periphery with tooth profile accuracy that guarantees reliable starter motor engagement cycle after cycle. The flywheel is dynamically balanced at the factory to minimize engine vibration and extend crankshaft main bearing life — a critical quality factor for heavy-duty truck applications operating at sustained high loads and RPM.

This flywheel fits Hino 700 Series heavy-duty trucks, tractor units, and vocational vehicles powered by the E13C 13-liter diesel engine. Also compatible with industrial equipment and generator sets using the same E13C powerplant. Always replace the flywheel bolts, pilot bearing, and clutch assembly when installing a new flywheel, and use a clutch alignment tool to ensure proper centering.
