ZF 0501.298.299 SEAL KIT for WG115/WG130/WG158

Overview

The ZF 0501.298.299 SEAL KIT (SKU: 0501.298.299) is an OEM genuine gasket and seal assembly engineered for the WG115, WG130, and WG158 transmission series. This critical service kit contains all elastomeric seals, O-rings, and gaskets required to restore hydraulic integrity within the transmission housing. It sits at every major fluid interface—between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, as well as the HOUSING REAR PART—preventing pressurized oil from escaping and maintaining clutch pack lubrication. Using this ZF seal kit ensures exact material compliance and dimensional precision for long service intervals.

Symptoms of Failure

• External oil seepage at housing joints: Worn seals allow ATF to weep from the mating surfaces between the HOUSING REAR PART and the main casing, leaving visible drips under the transmission.
• Erratic gear engagement or slipping: Internal seal degradation reduces line pressure, causing delayed shifts or clutch slip under load—especially in WG130 and WG158 units.
• Contaminated fluid from external debris ingress: Failed seals permit dirt and moisture to enter the housing, accelerating wear on bearings and valve bodies.
• Overheating due to low fluid level: Slow leaks from the HOUSING REAR PART seal can drop the sump level, leading to inadequate cooling and thermal damage.

Technical Specifications

Compatibility

This seal kit is designed for ZF WG-series powershift transmissions. Confirmed compatibility includes the WG115, WG130, WG158, WG160, WG200, and WG210 series. It also fits select variants of the WG180 and WG190 when used with the HOUS.FRONT SECT and TRANSMISSION HOUSING assemblies. Always verify your transmission serial number against ZF parts catalog before ordering.
