ZF 0501.211.171 SUCTION FILTER for WG100/WG130/WG131

Overview

The ZF 0501.211.171 SUCTION FILTER is a critical hydraulic component engineered specifically for the WG100, WG130, and WG131 series transmissions. This OEM genuine part, identified by SKU 0501.211.171, is positioned directly in the transmission’s oil sump, where it pre-filters the hydraulic fluid before it enters the pump. By capturing particulate contaminants and debris, this filter ensures that only clean oil circulates through the valve body, clutch packs, and torque converter. When replacing this filter, it is common practice to also inspect the 5838300626: DIFFERENTIAL HOUSING for cracks or wear, as both components share the same lubrication circuit.

Symptoms of Failure

When the ZF 0501.211.171 suction filter becomes clogged or degrades, operators will notice specific performance issues. Watch for these failure symptoms to avoid costly transmission damage:

• Erratic gear engagement or delayed shifting – A restricted filter starves the hydraulic system of oil, causing sluggish or harsh shifts, especially during cold starts.
• Transmission overheating – Reduced oil flow forces the transmission to work harder, leading to elevated operating temperatures and potential thermal damage.
• Whining or cavitation noise from the pump – As the filter becomes blocked, the pump struggles to draw fluid, producing a high-pitched whine or grinding sound.
• Intermittent loss of drive or gear slipping – Severe clogging can cause pressure drops, resulting in momentary loss of power delivery to the wheels.

Technical Specifications

Compatibility

This ZF suction filter is engineered for direct replacement in the following transmission models: WG100, WG130, and WG131. It is also compatible with certain variants of the WG180 and WG200 series when used in off-highway and industrial applications. For optimal performance, always pair this filter with a new 5838109009: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING during major overhauls. Additionally, the 2093209023: DIFFERENTIAL assembly should be checked for wear whenever the suction filter is replaced, as debris from a failing filter can accelerate differential wear.
