SPARKLING 304C CR Hydraulic Parts

The CATERPILLAR 332-1294 Valve Group – Pump Control (also referred to as CA3321294 or 3321294) is a precision-engineered hydraulic control component designed for CAT Mini Hydraulic Excavators, including models 304C CR, 305D CR, and 305E.

This pump control valve regulates the hydraulic pump output, ensuring efficient power delivery to various machine functions such as boom, bucket, swing, and travel operations. By precisely modulating hydraulic pressure and flow, the 332-1294 control valve helps optimize fuel efficiency, machine responsiveness, and overall operational safety.

Manufactured to exact OEM standards, this CAT valve GP is built from high-strength materials for long-lasting durability, corrosion resistance, and performance stability in harsh working environments. It's an ideal replacement part for restoring your machine’s hydraulic performance and reducing downtime.

Whether you're performing planned maintenance or emergency repairs, trust the 3321294 pump control valve to deliver reliable functionality and keep your mini excavator working at peak performance.

   The 283-3074 toggle switch is a 32V four-pole (four-circuit) control switch for Caterpillar excavators 311C/330D/345C (also fits 312C/312D/320C/320D/325C/330C/345D). It acts as a reliable circuit selector for functions like work mode (auto/manual), auxiliary hydraulics, or travel speed control, ensuring precise operation in heavy-duty construction.

Key Features
· OEM-Matched Precision: Exact 4-pole contact layout, M12×1 panel thread, and terminal pitch—plug-and-play for Cat cabs.
· Durable Construction: Reinforced PA66 housing (IP65 dust/waterproof); silver-plated copper contacts for low resistance (<50mΩ) and anti-oxidation.
· Stable Electrical Performance: 32V DC rated, 10A per pole; -40°C to 85°C operating temp for extreme worksites.
· Long Mechanical Life: 10,000+ toggle cycles; tactile detent for clear mode feedback, reducing misoperation.

Compatible Equipment
The 283-3074 toggle switch assembly is used across a wide range of Caterpillar machinery and engines: 
· Excavators: Models like the 311C, 312C/D, 320C/D, 323D, 325C/D, 330D, and 345C are compatible.
· Engines: It is compatible with various Cat engines, including the 3046, 3054, 3066, C7, and C9 series.
· Other Machinery: It also fits certain wheeled excavators and forest machines.

   The K5V212DPH1J8R-9NG4-AV is an OEM-compatible variable displacement axial piston main hydraulic pump, custom-engineered for Volvo EC300D/EC350D/EC380D and Hyundai R335LC-9V 30-38 ton excavators.

Key Features
· High-power output: 212cc displacement, max pressure 34.3 MPa, 1800 rpm rated speed—matches 150-190kW engine power for 30-38 ton excavators, ensuring efficient high-load operation.
· Precision flow control: Electro-hydraulic proportional control adjusts output per workload, cutting fuel consumption by 8% vs. standard pumps while maintaining smooth actuator response.
· Direct OEM fit: Exact mounting points, hydraulic ports, and SAE J518 flanges enable plug-and-play installation without system reconfiguration or adapter parts.
· Durable components: Hardened cylinder block, chrome-plated pistons, and wear-resistant valve plate extend service life; integrated pressure relief valve prevents overload damage.
