The Multiquip 8970700690 is a genuine OEM Crankshaft Pulley DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator series. As a direct OEM replacement, this pulley is manufactured to the exact dimensional and material specifications required by the Isuzu 4LE2 engine powering the DCA25USI. Sourced directly through Multiquip's authorized parts channel, 8970700690 ensures correct fitment without modification. If you are servicing a DCA25USI unit, verifying this part number against your machine's parts manual is always recommended before ordering.
Key Features
- Genuine OEM Isuzu 4LE2 Specification — Manufactured to the precise bore diameter, belt groove profile, and torque rating required by the 4LE2 engine, ensuring correct belt engagement and drive output.
- Direct Crankshaft Mount Replacement — Designed to mount directly onto the crankshaft snout of the Isuzu 4LE2, matching the original keyway, bolt pattern, and register fit of the factory component.
- DCA25USI Series Fitment — Confirmed fitment for the Multiquip DCA25USI ultra-silent diesel generator; always cross-reference part number 8970700690 with your serial-number-specific parts diagram.
- Sustained Alternator Drive Performance — A worn or cracked crankshaft pulley causes belt slippage, irregular alternator speed, and unstable generator output voltage; replacing it restores steady power delivery.
- Authorized Multiquip OEM Part — Supplied through Multiquip's genuine parts network, meaning this component meets the same production standards as the original part installed at the factory.
The crankshaft pulley is a drive component mounted at the front of the engine crankshaft. It transfers rotational power from the engine to the alternator and auxiliary systems via a drive belt, maintaining the precise speed ratio needed for stable electrical output. When the pulley wears, cracks, or becomes misaligned, belt tension is lost, generator output becomes erratic, and continued operation risks accelerated belt and bearing wear throughout the drive system.
