Overview
The ZF 4143.139.001 TYPE PLATE is a critical identification and specification component used in the HL 100 and HL 270 series transmission assemblies. This OEM sub-assembly plate provides essential operational data and alignment references for technicians during rebuilds or maintenance. The 4143.139.001 SKU is mounted directly to the main housing, ensuring that all service personnel can quickly verify the correct torque values and fluid capacities for the specific transmission variant. It is often replaced when the original plate becomes illegible or damaged, which can lead to costly misdiagnosis during field repairs. This plate interfaces directly with the 4143101031: HOUSING and the 4143301055: HOUSING to maintain structural integrity of the assembly.
Symptoms of Failure
- Illegible or faded type plate causing incorrect fluid fill: When the plate wears out, technicians cannot read the recommended oil grade, leading to premature gear wear and overheating in HL 100/HL 270 units.
- Misaligned mounting holes leading to vibration: A warped or corroded plate can cause the 0631329135: SPRING PIN to shear, resulting in loose fasteners and abnormal transmission noise during operation.
- Oil seepage around the plate perimeter: Deterioration of the plate gasket surface allows hydraulic fluid to bypass, often mistaken for a housing crack. This requires immediate replacement of the plate and the 4143298040: CASE seal.
- Incorrect shift pattern identification: A missing or damaged plate forces reliance on memory, increasing the risk of selecting the wrong replacement parts for WG or BP series transmissions.

Compatibility
This type plate is engineered for the ZF HL 100 and HL 270 series, but its mounting pattern also fits the following transmission families: BP 210 Series, BP 230 Series, WG 115 Series, WG 130 Series, WG 131 Series, WG 160 Series, WG 171 Series, WG 190 Series, WG 191 Series, WG 210 Series, WG 211 Series, WG 230 Series, and WG 260 Series. It is not compatible with WG 180 or WG 200 models without modification to the 4143301045: SCREEN SHEET mounting bracket. For proper installation, always pair with a new 4475280099: SCREW PLUG and 0636420051: COUNTERSUNK SCREW to prevent thread galling. The vent port should be fitted with a 0501200072: VENT VALVE for pressure equalization.
