ZF 4143.303.085 SHEET | OEM Genuine Part

Overview

The ZF 4143.303.085 SHEET is a precision-engineered OEM genuine component designed for critical load-bearing and spacing functions within ZF HL 100 and HL 270 series transmissions. This sheet acts as a shim or structural separator, ensuring correct axial clearances and alignment between adjacent assemblies. Specifically, it sits between the main housing and the connecting parts to maintain oil flow channels and prevent metal-on-metal contact. The SKU 4143.303.085 is manufactured to exact ZF tolerances, guaranteeing a perfect fit without modification. When paired with a 4143101022: HOUSING or a 4143301044: HOUSING, this sheet forms a sealed, stable foundation for the gear train.

Symptoms of Failure

When the ZF 4143.303.085 SHEET wears or becomes damaged, operators may notice specific operational issues. Look for these failure indicators:

• Intermittent gear slippage under load: A worn sheet can alter clutch pack clearances, causing hesitation or slipping during heavy hauling.
• Low hydraulic pressure warnings: If the sheet distorts, internal oil galleries may leak, triggering pressure drops on the dash display.
• Metallic debris in transmission fluid: Friction between the sheet and surrounding 0631329135: SPRING PIN components can generate fine metal particles.
• Audible rattling from the bell housing: Excessive clearance due to sheet wear produces a distinct metallic rattle at idle.

Technical Specifications

Compatibility

This genuine ZF sheet is engineered for use in the following transmission models: HL 100 Series, HL 270 Series, WG180, WG200, and WG210. It is also compatible with certain Ecomat 4HP and 5HP variants where the sheet serves as a spacer between the 0636302014: SCREW PLUG and the main housing. Always verify your transmission serial number before ordering.
