ZF 4681.298.019 REPAIR KIT for BP210/BP230 | OEM Genuine Part

Overview

This ZF 4681.298.019 REPAIR KIT is a critical service component engineered specifically for the BP210 and BP230 series transmissions. Designed to restore sealing integrity and internal pressure regulation, this OEM genuine part addresses the wear-prone elements within the valve body and hydraulic control circuit. The SKU 4681.298.019 replaces degraded seals, gaskets, and O-rings that are essential for maintaining proper clutch pack engagement and lubrication flow. When installed alongside a TRANSMISSION HOUSING, this kit ensures the entire assembly operates within factory tolerances, preventing cross-contamination between hydraulic circuits.

Symptoms of Failure

• Delayed or harsh shifting between gears: Worn seals inside the repair kit cause pressure loss, leading to sluggish engagement or abrupt gear changes in BP210/BP230 units.
• External oil seepage from the valve body area: Deteriorated gaskets allow transmission fluid to escape, often visible as drips near the pan or housing mating surfaces.
• Transmission slipping under load: Internal leakage reduces hydraulic clamping force on clutches, causing RPM flare without corresponding vehicle acceleration.
• Erratic shift patterns or neutral drops: Failed O-rings disrupt the governor pressure signal, resulting in unpredictable gear selection or temporary loss of drive.

Technical Specifications

Compatibility

This repair kit is validated for the ZF BP210 and BP230 series transmissions, which are commonly found in medium-duty commercial vehicles and off-highway equipment. It is also applicable to the WG180, WG200, and WG210 variants that share the same valve body architecture. The kit integrates directly with the HOUS.FRONT SECT and HOUSING REAR PART to create a sealed hydraulic chamber. For full assembly restoration, pair this kit with a new CASE to eliminate any warpage or corrosion on the mating surfaces.

Frequently Asked Questions

Q: Can this repair kit be used on a ZF WG180 transmission?
A: Yes, the 4681.298.019 kit is fully compatible with WG180, WG200, and WG210 models that utilize the same BP210/BP230 valve body architecture. Always verify the housing part numbers against your unit before installation.

Q: What is the typical service interval for replacing this kit?
A: ZF recommends replacing this repair kit during any major transmission overhaul, typically every 300,000 to 500,000 km (or when shifting symptoms appear). It is also mandatory to replace it if the transmission has suffered internal contamination from debris or water ingress.

Q: Do I need to replace the housing gaskets separately?
A: No. The 4681.298.019 kit includes all necessary seals and gaskets for the valve body and hydraulic control circuits. However, if you are replacing the TRANSMISSION HOUSING simultaneously, you will need the separate housing gasket set (part number 4681.298.020).
