ZF 4695.301.024 SCREW PLUG for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4695.301.024 SCREW PLUG is a critical sealing component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 4695.301.024, functions as a threaded closure within the transmission housing, preventing fluid loss and maintaining hydraulic pressure. It is typically installed in the lower sump area or side casing ports, where it interfaces directly with the 4695101002: HOUSING to secure the oil reservoir. Without this plug, the transmission cannot retain lubrication, leading to rapid wear of internal gears and bearings.

Symptoms of Failure

When the ZF 4695.301.024 screw plug degrades, operators often encounter specific performance issues. Look for these failure indicators:

• Transmission oil leaks from the sump drain port – A worn or cross-threaded plug allows ATF to seep out, leaving puddles under the vehicle.
• Gear slipping under load – Insufficient hydraulic pressure from a leaking plug causes delayed engagement or slipping in higher gears.
• Contaminated fluid due to debris ingress – A cracked plug seal permits dirt and moisture to enter the transmission, accelerating internal wear.
• Overheating during extended operation – Low fluid levels from a slow leak reduce cooling capacity, triggering thermal alarms.

Technical Specifications

Compatibility

This screw plug is designed for ZF’s WG-series industrial transmissions. It is a direct fit for the WG100, WG130, and WG131 models. It also serves as a replacement in the WG180 and WG200 series when used in conjunction with the 4695301021: HOUSING and 4695301022: COVER assemblies. For optimal sealing, always pair it with a new 0634801038: SEALING RING during installation.
