Overview
The ZF 2095.236.004 TUBE is a precision-engineered hydraulic fluid conduit designed for use within heavy-duty ZF construction machinery transmissions. This OEM genuine part channels pressurized oil to critical lubrication points and clutch packs, ensuring consistent thermal regulation and smooth gear engagement. As an original equipment component, the SKU 2095.236.004 guarantees exact fitment and material integrity, eliminating the risk of dimensional variances found in aftermarket substitutes. It sits within the transmission valve body assembly, connecting the main pump output to the upper housing galleries.
Symptoms of Failure
- Hydraulic oil seepage at transmission bell housing: A worn or cracked 2095.236.004 tube often manifests as slow oil weeping around the mid-case seam, leading to gradual fluid loss and eventual overheating.
- Delayed clutch engagement under load: When this tube develops internal restrictions or fractures, operators report a noticeable lag when shifting from neutral to forward or reverse on inclined surfaces.
- Erratic transmission pressure readings: A compromised tube disrupts the oil circuit, causing fluctuating pressure gauge values during cold starts or sustained operation, often misdiagnosed as pump failure.
- Audible whining from the gearbox: Insufficient oil delivery due to tube blockage creates cavitation noise, particularly at low RPM ranges during maneuvering.

Compatibility
This tube is a direct service part for the ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, telehandlers, and graders. It also applies to select variants of the ZF 4WG-200 and 6WG-200 models used in mid-size construction machinery. Always verify the transmission serial number against the ZF parts catalog to confirm interchangeability with earlier revision housings.
Installation Context
During replacement of the 2095.236.004 tube, technicians should inspect the adjacent 2095101022: TRANSMISSION HOUSING and 2095301025: TRANSMISSION HOUSING for cracks or thread damage. The tube’s sealing relies on a fresh 0634304731: O-RING at each connection point. Additionally, the 4475280150: SCREW PLUG securing the tube’s retention bracket must be torqued to 25 Nm to prevent vibration loosening.
