ZF 4681.298.017 REPAIR KIT for BP210/BP230/WG210 | OEM Genuine Part

Overview

The ZF 4681.298.017 REPAIR KIT is a critical OEM genuine service assembly designed to restore the sealing and filtration integrity within ZF BP210, BP230, and WG210 series transmissions. This kit contains all necessary gaskets, seals, and wear components required to address internal leakage paths and contamination buildup. Positioned within the main gear train housing, this repair kit directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to prevent fluid migration between chambers. The SKU 4681.298.017 is engineered to match factory tolerances, ensuring that the HOUSING REAR PART and HOUSING REAR SECTION maintain proper pressure boundaries during operation.

Symptoms of Failure

• External oil seepage at housing joints: When the 4681.298.017 repair kit seals degrade, you will notice fluid weeping between the transmission housing and the rear section, particularly after extended highway operation.
• Intermittent gear slipping under load: Worn internal seals from this kit cause pressure loss in the clutch packs, leading to hesitation or slipping when the transmission shifts from second to third gear.
• Contaminated transmission fluid with metallic particles: A failing repair kit allows debris to bypass the filtration screen, resulting in dark, gritty fluid that accelerates wear on the SCREEN SHEET components.
• Audible whining noise from the pump area: Air ingestion through compromised seals in this kit creates cavitation, producing a high-pitched whine that intensifies during cold starts.

Technical Specifications

Compatibility

This repair kit is engineered for ZF BP210, BP230, and WG210 series transmissions. It is also compatible with the WG180 and WG200 models when used in conjunction with the FIXING PLATE and appropriate CAP SCREW variants. The kit fits all standard ZF drop-box and transfer case configurations where the housing sections are bolted together using the SCREEN SHEET (fine mesh) for debris filtration. Always verify your transmission serial number against the ZF parts catalog to confirm fitment for non-standard applications.

Frequently Asked Questions

Q: Can I install the 4681.298.017 repair kit without replacing the housing sections?
A: Yes, this kit is designed to refresh the sealing surfaces within your existing TRANSMISSION HOUSING and HOUS.FRONT SECT. However, always inspect the mating surfaces for scoring or corrosion before reassembly.

Q: How often should this repair kit be replaced in a BP210 series transmission?
A: ZF recommends replacing the 4681.298.017 kit every 500,000 km or during any major overhaul where the HOUSING REAR PART is removed. More frequent replacement may be needed in dusty or high-torque applications.

Q: Does this kit include the CYLINDRICAL PIN for alignment?
A: No, the cylindrical pin is sold separately. You will need to order part 0631306816 to ensure proper alignment of the HOUSING REAR SECTION during installation.
