Throttle motor 300513-00008 used for Doosan DX300LC excavator spare parts
![]()
This Doosan DX300LC excavator spare parts Throttle motor 300513‑00008 is original electric stepping throttle actuator exclusively matched for Doosan DX300LC crawler excavator, classified as critical engine speed control Doosan Excavator spare parts for excavator engine electronic control system overhaul and daily maintenance.
Excavator fleets often encounter typical throttle motor failures after long‑time construction work: engine speed cannot adjust normally, throttle motor no response, unstable engine RPM, cannot idle or cannot reach high speed, fault code alarm and digging power insufficient. As fully interchange OEM spare part, this 300513‑00008 throttle motor fully matches original mounting dimension, dual pull‑cable stroke and multi‑pin electrical plug definition of Doosan DX300LC excavator. No bracket refitting or complicated controller parameter recalibration required, effectively reduce on‑site repair downtime and avoid construction efficiency loss caused by abnormal engine speed regulation.
Adopting high‑precision stepping motor core, wear‑resistant inner gear set, durable steel pull‑cable assembly and sealed plastic housing, this throttle motor adapts to harsh construction‑site environments including strong vibration, dust accumulation, muddy water splash and large temperature fluctuation. Every finished throttle motor passes stepping action test, cable stroke test and vibration aging inspection before shipment, fully complying with original factory quality standards of authentic Doosan Excavator spare parts.

Smooth precise stepping speed adjustment & real‑time signal feedback
High‑quality stepping motor core realizes accurate throttle pull‑in action, stably complete idle‑high speed switching, avoid engine speed drifting and jumping faults, far more dependable than low‑cost generic Doosan Excavator spare parts.
Durable gear transmission & anti‑wear dual pull‑cable assembly
Wear‑resistant internal gear set reduces motor stalling risk; double steel wire pull‑cable with anti‑abrasion outer sheath resists bending and vibration fatigue, extend whole‑set service life.
Dust‑proof sealed outer housing structure
Integrated sealed plastic housing prevents construction dust, muddy water from invading internal motor and gear components, effectively reduce gear rust and motor short‑circuit failure risk under field harsh conditions.
1:1 OEM original plug‑and‑play installation compatibility
Bracket mounting hole layout, pull‑cable effective stroke and multi‑pin connector pin definition are fully consistent with OEM original throttle motor, direct replacement for matched Doosan DX300LC excavator engine throttle control system overhaul repair.
This 300513‑00008 throttle motor is tailor‑made for engine electronic speed regulating system of Doosan DX300LC crawler excavator. Receives command signal from excavator main controller, drives dual pull‑cable to pull engine fuel pump throttle lever, realize remote adjustment of engine RPM, which directly affects digging power, fuel consumption and working mode switching.
