ZF 4108.015.056 P 5300 | OEM Genuine Part

Overview

The ZF 4108.015.056 P 5300 is an OEM genuine hydraulic control valve assembly engineered for the demanding environments of construction machinery. This precision component governs clutch engagement and gear selection within the transmission’s valve body, directing oil flow to the appropriate clutches for smooth shifting under heavy loads. As a critical fluid power interface, the SKU 4108.015.056 ensures consistent pressure regulation and prevents cross-leakage between circuits. It is typically mounted directly onto the main transmission housing, where it interfaces with the 4108101166 HOUSING to form a sealed hydraulic manifold. Without this part, the transmission cannot modulate torque converter lockup or range shifts, making it indispensable for wheel loaders, graders, and dump trucks operating in high-cycle applications.

Symptoms of Failure

• Delayed or harsh gear engagement: When the valve spools wear or stick, operators experience a noticeable lag when shifting from neutral to drive, often accompanied by a jarring clunk. This is a common search query for “ZF transmission slow engagement construction equipment.”
• Transmission oil leaks at the valve body gasket: Deteriorated sealing surfaces cause hydraulic fluid to weep around the mounting flange. Look for drips near the 0501325471 SEALING RING interface, leading to low oil levels and eventual overheating.
• Intermittent gear slip under load: A failing 4108.015.056 cannot maintain clutch holding pressure, causing the transmission to momentarily lose power on inclines or during bucket loading. This symptom often triggers “ZF WG200 slipping under load” searches.
• Erratic shift patterns or limp mode: Internal contamination or valve bore scoring disrupts pilot pressure signals, forcing the transmission controller to default to a single gear. Checking the 0730365280 TYPE PLATE for correct calibration data is essential during diagnosis.

Technical Specifications

Compatibility

This hydraulic control valve is designed for ZF’s powershift transmission series commonly found in construction machinery. It is a direct fit for the WG180 and WG200 models, which are used in compact wheel loaders and backhoes. Additionally, it is compatible with the WG150 and WG250 series when paired with the correct 0501215601 OIL LEVEL GAGE to verify proper fluid height. For heavy-duty applications in the Ecomat 4 and 6HP families, this part serves as a direct replacement for earlier valve assemblies, provided the housing bore dimensions match. Always cross-reference the type plate data before installation.
