SPARKLING RD451‑64053 Excavator Part – Precision & Durability

The Kubota Oil Cooler (part nos. RD451‑64050, RD451‑64053, RD551‑64050, RD551‑64052) is a premium hydraulic oil radiator engineered for various Kubota excavators and compact machines, including models like KX057‑4, U48‑4, U55‑4, and more. This high-performance aluminium oil cooler ensures efficient heat dissipation and maintains optimal hydraulic oil temperatures under continuous heavy-duty operation. Manufactured to OEM standards and available in both genuine and aftermarket options, it offers excellent durability, corrosion resistance, and a perfect drop-in fit.

   The 119005-77051 Intake Air Heater is a core cold-start component for Yanmar 4TNV94 engines in Komatsu skid steers CK20-1, CK25-1, and loader SK1020-5. It preheats intake air to ensure reliable cold starts, smooth idle, and reduced emissions in low-temperature conditions, critical for consistent operation of construction machinery.

Function: This component is powered by the vehicle's battery and designed to heat the incoming air charge, which facilitates faster starts, reduces white smoke (cold emissions), and minimizes engine wear during ignition in chilly conditions.

Compatible Engines and Equipment:
· Yanmar Engines: 4TNV94L, 4TNV98, 4TNE88, and 4TNV98T series diesel engines.
· Komatsu Engines: 4D94E and 4D94LE engines.
· Komatsu Equipment: CK20-1, CK25-1, SK1020-5, SK1026-5, and PC80MR-3.

   SPARKLING MACHINERY NEW WA300 WA320 WA350 WA380 WA400 WA420 WA450 421-43-26470 Parking Switch is a dedicated safety control component for Komatsu WA300, WA320, WA350, WA380, WA400, WA420, and WA450 wheel loaders (widely used in construction, mining, and material handling). As the "parking safety trigger", it activates the excavator’s parking brake system—securing the machine in place during shutdowns or when parked on slopes, while preventing accidental movement that risks equipment damage or on-site injuries during loading, unloading, or idle periods.
   Meeting Komatsu OEM standards (part no. 421-43-26470), it endures -30°C to 85°C temperatures, resists dust and vibration, and ensures stable electrical signal transmission. Strict testing guarantees seamless compatibility with the seven Komatsu models and long-term parking safety reliability.
