Overview
The ZF 4108.015.061 P 5300 is an OEM genuine component engineered for the demanding environment of construction machinery transmissions. This precision-machined part functions as a critical interface within the gear train, ensuring consistent torque transfer and alignment under heavy loads. Specifically, it sits within the upper valve body or shift control assembly of select ZF powershift transmissions, regulating hydraulic flow for clutch engagement. The SKU 4108.015.061 is a direct factory replacement, guaranteeing exact fit and material integrity. When installed alongside the 4108101166 HOUSING, it forms a sealed unit that prevents contamination and maintains system pressure.
Symptoms of Failure
When the ZF 4108.015.061 wears out, operators will notice distinct performance degradation. Look for these specific failure symptoms to diagnose the issue:
- Erratic clutch engagement or gear slipping under load – A worn part disrupts hydraulic balance, causing delayed or incomplete shifts.
- External oil leaks near the valve body – Cracks or deformation in the component allow transmission fluid to escape, often pooling around the 0501325471 SEALING RING interface.
- Intermittent loss of drive in forward or reverse – The part may fail to maintain proper spool position, leading to sudden power loss.
- Increased operating temperature due to internal bypass – Fluid bypasses the intended circuit, generating excess heat and accelerating wear on adjacent parts.
