Overview
The ZF 4681.303.006 SCREEN SHEET is a critical filtration component engineered for the BP210, BP230, WG190, and WG210 series transmissions. This OEM genuine part, identified by SKU 4681.303.006, sits within the transmission’s hydraulic sump or valve body area, where it captures particulate contaminants from the circulating oil. By ensuring only clean fluid reaches precision components, this screen sheet prevents abrasive wear and maintains consistent hydraulic pressure. It is often replaced during a major overhaul alongside the TRANSMISSION HOUSING to guarantee a contaminant-free environment.
Symptoms of Failure
- Erratic gear engagement or delayed shifting: A clogged screen sheet restricts oil flow, causing hesitation when the transmission attempts to shift under load.
- Low hydraulic pressure warnings: Debris buildup on the screen sheet starves the pump, triggering pressure drops that affect clutch pack actuation.
- Overheating transmission fluid: Restricted flow forces the system to work harder, generating excess heat that degrades oil viscosity and accelerates wear.
- Metallic debris in the oil pan: A torn or degraded screen sheet allows particles to circulate, leading to scoring on bearings and gears.

Compatibility
This screen sheet is engineered for ZF’s BP and WG series powershift transmissions. It directly fits the BP210, BP230, WG190, and WG210 models. It also serves as a service part for the WG180 and WG200 series when paired with the HOUSING REAR SECTION. Always verify your transmission’s serial number before ordering, as minor revisions in the sump design may require an alternative screen variant.

Frequently Asked Questions
Q: Can I clean and reuse the 4681.303.006 screen sheet instead of replacing it?
A: While the stainless steel mesh can be cleaned with solvent, ZF recommends replacement during any transmission rebuild. The polymer frame degrades over time, and microscopic tears may not be visible to the naked eye.
Q: Does this screen sheet fit the ZF WG180 transmission?
A: Yes, the 4681.303.006 is compatible with WG180 models when used with the correct HOUSING REAR SECTION. Verify your sump depth before installation.
Q: What torque should I use for the cap screws securing this screen sheet?
A: For the CAP SCREW (0636100801), apply 25 Nm (18.4 lb-ft). Over-tightening can distort the screen frame and cause bypass leakage.
