ZF 4657.301.035 SCREEN SHEET for WG190/WG210 | OEM Genuine Part

Overview

The ZF 4657.301.035 SCREEN SHEET is a critical filtration component engineered for the WG190 and WG210 transmission series. Positioned within the hydraulic control circuit, this OEM genuine part ensures that transmission fluid is free from particulate contaminants before it reaches precision valves and clutch packs. By maintaining fluid cleanliness, the screen sheet directly supports consistent shift quality and extends the service life of the entire assembly. The SKU 4657.301.035 is a direct replacement designed to meet original factory specifications, making it an essential item for any rebuild or preventive maintenance procedure on ZF off-highway transmissions.

Symptoms of Failure

When the ZF 4657.301.035 screen sheet becomes clogged or degrades, operators may notice several distinct performance issues. Delayed or harsh gear engagement is a common symptom, as restricted oil flow prevents the transmission from building pressure quickly. Another frequent complaint is intermittent gear slipping under load, which occurs when the hydraulic system cannot maintain adequate clamping force on the clutches. Additionally, erratic shift timing or a whining noise from the transmission pump can indicate that the screen is partially blocked, forcing the pump to work harder. If left unaddressed, a failed screen sheet can lead to catastrophic internal damage, making early replacement of part 4657.301.035 a cost-effective repair.

Technical Specifications

Compatibility

This screen sheet is specifically designed for the ZF WG190 and WG210 series transmissions, which are commonly found in wheel loaders, telehandlers, and other heavy equipment. While the primary application is the WG190 and WG210, the 4657.301.035 may also be compatible with the WG180 and WG200 series when used in similar hydraulic filtration circuits. Always verify the part number against your transmission’s parts manual to ensure a proper fit. When replacing this screen, it is common practice to also inspect the TRANSMISSION HOUSING for debris and ensure the HOUS.FRONT SECT and HOUSING REAR PART are clean and free of scoring. The screen is secured in place using a CYLINDRICAL PIN to prevent movement during operation.

Frequently Asked Questions

Q: How often should the ZF 4657.301.035 screen sheet be replaced?
A: It is recommended to replace this screen sheet during every major transmission overhaul or when performing a fluid change after a clutch failure. In normal operating conditions, inspect the screen every 2,000 hours of service.

Q: Can I clean and reuse the 4657.301.035 screen sheet?
A: While the stainless steel mesh can be cleaned, ZF recommends replacement with a genuine part to guarantee proper micron retention. Reusing a screen that has been deformed or partially clogged can lead to inconsistent filtration and eventual transmission damage.

Q: Is the 4657.301.035 the same as the 4657301034 screen sheet?
A: No, these are different part numbers. The 4657.301.035 is specific to the WG190/WG210 series, while the 4657301034 is used in other ZF models. Always confirm your transmission’s parts list before ordering.
