Overview
The ZF 4657.303.018 SCREEN SHEET is a critical filtration component engineered for the WG160 series and compatible heavy-duty transmission platforms. This OEM genuine part sits within the oil sump or valve body assembly, where it acts as a primary barrier against particulate contamination. By trapping metallic debris, clutch wear particles, and carbon deposits, the screen sheet ensures that only clean hydraulic fluid circulates through the transmission’s precision channels. The SKU 4657.303.018 is precision-stamped to maintain consistent mesh density, directly supporting the longevity of adjacent assemblies such as the TRANSMISSION HOUSING and the HOUS.FRONT SECT.
Symptoms of Failure
- Intermittent gear slipping under load: A clogged screen sheet restricts oil flow to the clutch packs, causing delayed engagement or slipping during uphill hauling.
- Erratic shift timing: When the screen sheet becomes obstructed, the valve body receives inconsistent pressure, leading to harsh or delayed shifts between gears.
- Low transmission oil pressure warnings: Debris buildup on the 4657.303.018 screen sheet starves the oil pump, triggering dashboard pressure alerts and potential torque converter shudder.
- Visible metallic debris in the oil pan: A failed screen sheet allows particles to bypass filtration, often found during routine oil changes as glitter or sludge in the sump.

Frequently Asked Questions
Q: How often should the 4657.303.018 screen sheet be replaced?
A: ZF recommends inspecting the screen sheet during every major transmission overhaul or at 500,000 km intervals. Replace immediately if you observe clogging or deformation.
Q: Can I clean and reuse this screen sheet instead of replacing it?
A: While the stainless steel mesh can be cleaned with solvent, ZF advises replacement with a genuine part to guarantee mesh integrity. Reusing a stretched or torn screen sheet risks debris bypassing into the TRANSMISSION HOUSING.
Q: Is this screen sheet compatible with the ZF WG180 transmission?
A: Yes, the 4657.303.018 is compatible with the WG180 model, provided the transmission uses the standard sump configuration. Always cross-reference with your parts manual for the correct FIXING PLATE orientation.
