ZF 4143.152.007 COUPLING for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.152.007 COUPLING is a critical torque-transfer component engineered specifically for the HL 100 and HL 270 series transmissions. This OEM genuine part acts as the mechanical link between the engine output and the transmission input shaft, ensuring smooth power delivery under heavy industrial loads. The SKU 4143.152.007 is precision-machined to ZF’s original tolerances, making it essential for maintaining driveline integrity in high-stress environments. When installed alongside the 4143101016 HOUSING and 4143301039 HOUSING, this coupling forms the core of the clutch pack assembly, absorbing torsional vibrations that would otherwise damage downstream gears.

Symptoms of Failure

• Transmission oil leaks near the bell housing: A worn 4143.152.007 coupling often compromises the seal interface, causing fluid to weep from the joint. This is a common long-tail search query for “ZF HL 270 oil leak coupling.”
• Gear slipping under load: When the coupling splines wear, the transmission may hesitate or slip during acceleration, particularly in the HL 100 series. Operators searching “ZF transmission slipping when loaded” frequently encounter this issue.
• Abnormal driveline vibration: A degraded coupling fails to dampen harmonics, leading to a noticeable shudder at specific RPM ranges. This symptom is often reported as “ZF HL 270 vibration at 1500 RPM.”
• Metallic debris in the oil pan: As the coupling surface erodes, fine metal particles contaminate the hydraulic fluid, triggering filter blockages and valve body wear.

Technical Specifications

Compatibility

This coupling is designed for ZF’s HL 100 and HL 270 series, but it also fits several other heavy-duty models that share the same spline geometry. Compatible transmissions include the WG180, WG200, WG210, and the 4WG-200 series. It is also used in certain off-highway variants of the ZF 6HP and 8HP ranges where the input shaft diameter matches 38 mm. Always verify the spline count (typically 24 teeth) before installation. For proper sealing, pair this part with the 0501318136 GASKET and secure it using the 0636101084 CAP SCREW to prevent loosening under high torque.
