Overview
The ZF 4657.303.049 SCREEN SHEET is a precision-engineered filtration component designed specifically for the WG190 and WG210 transmission series. Positioned within the hydraulic control circuit, this screen sheet captures particulate contaminants before they can enter critical valve bodies and clutch assemblies. As an OEM genuine part, SKU 4657.303.049 ensures exact fitment and consistent fluid flow, directly supporting the longevity of adjacent assemblies such as the 4657101080: TRANSMISSION HOUSING and the 4657201167: HOUS.FRONT SECT. Without this screen, debris can bypass filtration and accelerate wear on internal components.
Symptoms of Failure
- Erratic shift timing or delayed engagement – A clogged screen sheet restricts hydraulic pressure, causing hesitation when shifting between gears.
- Intermittent transmission overheating – Reduced fluid flow through the filter leads to higher operating temperatures, especially under load.
- Whining or humming noise from the transmission pump – The pump works harder to pull fluid through a blocked screen, generating audible stress sounds.
- Visible metallic debris in the transmission pan – When the screen sheet fails, particles bypass filtration and accumulate in the oil pan, indicating internal wear.

Frequently Asked Questions
Q: Can I clean and reuse the 4657.303.049 screen sheet?
No. This is a single-use filtration component. Cleaning may damage the mesh integrity, and any embedded debris can cause internal leakage. Always replace with a new OEM screen sheet during transmission overhaul.
Q: How often should this screen sheet be replaced?
ZF recommends replacement every 500 operating hours or during any major transmission service. If you observe metallic particles in the oil, replace the screen sheet immediately along with the 4656301148: FIXING PLATE and associated cap screws.
Q: Does this part fit the ZF WG180 transmission?
Yes, the 4657.303.049 is compatible with WG180, WG190, WG200, and WG210 series. However, always cross-reference your transmission serial number with the 4657101080: TRANSMISSION HOUSING to confirm the correct mounting orientation.
