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

   SPARKLING MACHINERY NEW 7272-03100 Spool is a core hydraulic control component for compatible Volvo excavator models (widely used in construction, mining, and infrastructure projects). As the "hydraulic flow regulator core", it precisely controls the direction and volume of hydraulic oil within the excavator’s valve body—enabling smooth operation of key functions like boom lifting, bucket digging, and arm movement during heavy-duty tasks. This prevents hydraulic flow (disorders) and ensures consistent equipment performance, while avoiding pressure mismatches that damage valves or cylinders.
   Meeting Volvo OEM standards (part no. 7272-03100), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and wear, and guarantees stable movement. Strict testing ensures seamless compatibility with applicable Volvo models and long-term hydraulic system reliability.
