High-Quality SPARKLING ZF Transmission Parts for Excavators

The ZF 4472397016 (also listed as 4472.397.016 / 4472-397-016) Bearing Pin is a high-precision component designed to provide reliable rotational alignment and structural support in ZF transmission and axle assemblies. Built from heat-treated, wear-resistant steel, this pin ensures long-term durability and smooth mechanical movement under heavy-duty conditions.

It is a perfect fit for ZF machinery applications where stability, strength, and OEM compatibility are essential. Each pin is manufactured to strict tolerances and undergoes rigorous quality control to meet or exceed OEM standards.

Part number 4143-142-013 (also written as 4143.142.013) refers to a Gear Shift Sensor (sometimes incorrectly listed as an oil pump in some catalogs) manufactured by ZF. It is primarily used in the heavy-duty ZF transmission assemblies found in various wheeled excavators and other construction equipment.

Part Name: Gear Shift Sensor / Transmission Sensor.
Manufacturer: ZF (Zahnradfabrik Friedrichshafen).
Function: This sensor is crucial for detecting gear positions and ensuring smooth and correct gear shifting within the transmission system.
Weight: Approximately 3.1 kg.

The 4143-142-013 sensor is compatible with several models across various brands:
Hyundai: Models R170W-7A and R200W-7.
Doosan / Daewoo: May be found in certain wheeled excavator models that utilize compatible ZF transmissions.
ZF Transmissions: Specifically used in the ZF HL 290 and potentially other ZF series like 2HL270 and 2HL290 transmissions

   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 HYUNDAI Check Valve 31N8-17420 / XKCG-00456 is a genuine replacement component designed for the main control valve system of Hyundai 9-Series crawler excavators, specifically model R300LC-9.

This check valve plays a critical role in hydraulic flow control. It allows fluid to move in one direction while preventing backflow, which protects the hydraulic system from pressure surges and maintains stable performance during demanding excavation operations.

Manufactured to OEM specifications, this valve offers precision engineering, corrosion resistance, and a durable internal seal — ensuring reliable operation, even under extreme pressure and high-duty cycles. It's ideal for both routine maintenance and emergency repairs when performance and safety are non-negotiable.
