Multiquip 1553325162 Flywheel Bolt

The Multiquip 1553325162 Flywheel Bolt is a genuine OEM component designed for DLW300ES and DLW400ES series diesel light welders. Sourced directly from Multiquip, this flywheel bolt meets the exact specifications required for secure flywheel retention on these machines. Correct torque and clamping integrity at the flywheel is critical to proper engine operation, making an exact-match replacement essential. DHS Equipment stocks this part to keep your Multiquip welder running with confidence.

Key Features

• Genuine OEM Fastener Grade — Manufactured to Multiquip's specified tensile strength and thread pitch, ensuring the flywheel is held to the correct clamping load without risk of fastener failure.
• Drop-In Installation — Matches the original thread specification and head geometry exactly, fitting the flywheel hub on DLW-series machines without modification to hardware or mating surfaces.
• Confirmed Fitment for DLW Welders — Verified for DLW300ES and DLW400ES diesel light welder models, covering both standard and ESA/ESA1 configurations.
• Flywheel Stability Under Load — A properly torqued flywheel bolt maintains rotational balance and consistent power transfer from the engine; a loose or failed bolt can cause flywheel movement, vibration, and engine damage.
• Critical Safety Hardware — As a primary flywheel retention fastener, this bolt is a safety-critical component; using a correct OEM specification replacement is essential to prevent mechanical failure during operation.

The flywheel bolt secures the flywheel to the engine crankshaft, locking it in precise rotational alignment so the engine can transfer power consistently to the alternator and welding system. If this bolt loosens or fails, the flywheel can shift on the crankshaft, causing severe vibration, loss of output, and potential engine damage. Replacing a worn or compromised flywheel bolt with a correct OEM-spec fastener restores the mechanical integrity of the drivetrain and protects the broader engine assembly from secondary damage.
