ZF 4108.016.058 P 4300 | OEM Genuine Part

Overview

The ZF 4108.016.058 P 4300 is an OEM genuine part engineered for the demanding environment of construction machinery transmissions. This component functions as a critical hydraulic control element within the valve body assembly, regulating oil flow to clutch packs and shift actuators. Positioned directly in the main control circuit of the transmission, it ensures precise pressure modulation during gear changes. The SKU 4108.016.058 is manufactured to ZF’s original specifications, guaranteeing a direct fit and reliable performance in heavy-duty applications. When installed alongside the 4108101165 HOUSING, it forms a sealed unit that prevents contamination and maintains consistent hydraulic pressure.

Symptoms of Failure

• Delayed or harsh shifting: A worn 4108.016.058 can cause sluggish engagement between gears, particularly under load, as internal spools stick or bypass fluid.
• Hydraulic oil leaks around the valve body: Degraded sealing surfaces lead to external seepage, often visible as drips near the transmission pan or housing joint.
• Intermittent gear slipping under torque: When the part fails to maintain pressure, the transmission may momentarily lose drive, especially during uphill climbs or heavy digging.
• Erratic clutch engagement: Operators may notice a shudder or vibration when the transmission shifts, indicating inconsistent fluid delivery to the clutch packs.

Technical Specifications

Compatibility

This genuine ZF part is designed for use in the P 4300 series valve body, which is found in several heavy-duty transmission models. Based on its hydraulic spool configuration, the 4108.016.058 is compatible with the following ZF transmissions commonly used in construction machinery: WG180, WG200, WG211, and WG250. It also fits select variants of the Ecomat 4HP and 6HP series when used in off-highway equipment. For proper sealing during installation, always replace the 0636302015 SCREW PLUG and the 0501325471 SEALING RING to prevent fluid bypass. The 0730365280 TYPE PLATE should also be inspected for legibility to ensure correct part identification during future service.
