   SPARKLING MACHINERY NEW PC27MR PC30MR PC35MR PC45MR PC490 PC55MR 708-3S-14290/708-3S-14250 Piston Subassembly is a dedicated, high-performance hydraulic component exclusively engineered for KOMATSU PC27MR, PC30MR, PC35MR, PC45MR, PC490, and PC55MR crawler excavators—covering mini to heavy-duty models widely used in urban construction, landscaping, mining, and large-scale infrastructure projects. As a core part of the excavator’s hydraulic cylinder system, it converts hydraulic pressure into linear motion to drive key mechanisms (boom, arm, bucket), ensuring powerful and smooth operation during tasks like trench digging, rock breaking, and material loading. This function is vital for maintaining sufficient digging force, optimizing operational efficiency, and avoiding unplanned downtime caused by cylinder performance failures.

• Function: Operates within the hydraulic main pump (typically the LPD28 or LPV30 models) to control fluid displacement and system pressure.
• Dimensions: Approximately 22mm x 40mm.
• Compatible Equipment: Primarily used in Komatsu "MR" series mini-excavators:
  • PC27MR, PC30MR, PC35MR, PC40MR, PC45MR, PC50MR, and PC55MR.

   The 279-1341 motor shaft is a heavy-duty travel motor drive shaft for Caterpillar mini excavators 305.5/305.5D/305.5E (also fits 304C CR/305C CR/306). It transmits torque from the hydraulic travel motor to the final drive gearbox, enabling smooth track movement in construction/landscaping applications. As a direct OEM replacement (interchangeable with 2791341), it restores reliable power transfer and prevents drive system downtime.

Key Features
· OEM-Matched Precision: Forged 42CrMo alloy steel, exact spline dimensions, and flange fit—no modification needed for Cat models.
· Durable Construction: Carburized surface (58–62 HRC) for wear resistance; precision-ground journals for bearing alignment.
· High Torque Capacity: Rated for 2,800 N·m max torque; balanced to G6.3 standard for low vibration.
· Plug-and-Play Installation: Direct bolt-on fit with pre-drilled mounting holes; 30-minute replacement, no special tools required.
· Long Service Life: Shot-peened for fatigue resistance; 10,000+ hours lifespan; outlasts generic shafts by 60%.

Compatible Equipment
· Mini Excavators: Caterpillar 305.5, 305.5D, 305.5E, 304C CR, 305C CR, 306.
· Interchangeable Part Numbers: 279-1341, 2791341.

   The 6732375 Water Tank is a premium coolant expansion tank for Volvo EC200B, EC210B, EC210C, and EC240B excavators, a core part of the engine cooling system. It stores and regulates coolant volume, accommodates thermal expansion/contraction, maintains stable system pressure, and prevents coolant overflow, ensuring consistent engine operating temperature and protecting against overheating-related damage.

Key Features
· OEM-Matched Fit: Exact dimensions, mounting points, and interface specs for direct, modification-free installation.
· Durable Material: High-impact reinforced plastic resists corrosion, vibration, and extreme temperatures.
· Pressure Stability: Integrated pressure cap maintains optimal system pressure, improving cooling efficiency.
· Leak-Proof Design: Precision-molded seals and reinforced joints prevent coolant leaks during operation.
· Integrated Level Indicator: Clear sight glass for quick coolant level checks, simplifying maintenance.

Compatible Equipment
Volvo Excavators: EC200B / EC210B / EC210C; EC240B / EC240C; EC290B / EC290C; EC360B / EC360C; EC460B / EC460C
