Overview
The ZF 2098.240.018 OIL TANK (SKU: 2098.240.018) is an OEM genuine component engineered to store and supply hydraulic fluid under pressure to the transmission lubrication and clutch actuation circuits. Positioned externally on the transmission assembly, this reservoir ensures a consistent oil supply to critical rotating elements, including the gear sets and bearings. It integrates directly with the 2098117002: HOUSING to form a sealed fluid containment system. Maintaining the integrity of this tank is essential for preventing cavitation and ensuring proper thermal management of the transmission oil.
Symptoms of Failure
- External oil seepage around the tank seam: Cracks or porosity in the tank body lead to visible fluid loss, often mistaken for a simple gasket issue.
- Erratic gear engagement or slipping: Insufficient oil volume due to a leaking tank starves the clutch packs, causing delayed or harsh shifts under load.
- Transmission overheating: A compromised tank reduces the oil reservoir capacity, diminishing the system’s ability to dissipate heat during prolonged operation.
- Low oil pressure warnings: The control unit detects a drop in line pressure when the tank cannot maintain adequate fluid supply to the pump inlet.

Compatibility
This oil tank is primarily designed for use in ZF WG180 and WG200 series powershift transmissions commonly found in construction machinery such as wheel loaders and graders. It also fits select WG150 and WG250 variants where the external reservoir configuration is employed. Always verify the mounting flange pattern against your existing 2098301052: REAR AXLE HOUS. to confirm compatibility. The tank is secured using 0636103300: STUD and 0637101164: HEXAGON NUT fasteners, which must be replaced if corroded.
