Overview
The ZF 0750.147.084 HOSE PIPE is a critical fluid conduit engineered specifically for the WG181 and WG201 transmission series. This OEM genuine part ensures precise hydraulic pressure delivery within the valve body assembly, directly influencing clutch engagement and torque converter lock-up. The SKU 0750.147.084 serves as the primary channel for transmission oil flow between the pump and the cooler circuit, maintaining optimal thermal regulation. Without this hose pipe, the transmission cannot sustain the hydraulic integrity required for heavy-duty commercial applications. It is designed to withstand high-pressure spikes and thermal cycling common in construction and agricultural machinery.
Symptoms of Failure
- Transmission fluid puddles under vehicle: A cracked or swollen 0750.147.084 hose pipe will leak ATF, often pooling near the bell housing or cooler lines. This is a common long-tail search query for “ZF WG181 oil leak from hose.”
- Delayed or harsh gear engagement: When the hose pipe loses internal pressure due to micro-fractures, hydraulic force drops, causing “ZF WG201 gear slipping under load” symptoms.
- Overheating transmission: A restricted or collapsed hose pipe reduces cooler flow, triggering “transmission temperature warning light” in ZF off-highway equipment.
- Erratic shift patterns: Air ingress through a degraded hose pipe leads to “ZF transmission jerking between gears” complaints, particularly in stop-and-go operations.

Compatibility
This hose pipe is factory-specified for the ZF WG181 and WG201 series, which include the WG180, WG200, and their derivative models (WG181, WG201). It is also compatible with the WG 180 Series and WG 200 Series used in wheel loaders, dump trucks, and forklifts. The 0750.147.084 interfaces directly with the 4644101160: TRANSMISSION HOUSING and the 4644301323: TRANSMISSION HOUSING to form a sealed fluid circuit. For secure mounting, it pairs with the 4644301189: THREADED BUSH and the 4475280043: SCREW PLUG to prevent leakage at connection points. Always verify your transmission model suffix before ordering.
