ZF 4681.183.001 LOOSE PARTS for BP210 | OEM Genuine Part

Overview

The ZF 4681.183.001 LOOSE PARTS kit is a critical service component designed exclusively for the BP210 series transmission. This genuine OEM assembly contains the necessary loose hardware and fasteners required to secure and align internal transmission sections during overhaul or repair. Specifically, this kit interfaces with the main casing structure, ensuring that the TRANSMISSION HOUSING remains properly sealed and structurally sound under heavy load. The SKU 4681.183.001 is often ordered alongside major housing replacements to guarantee that every bolt, pin, and plate meets ZF’s original manufacturing tolerances. Without this loose parts set, reassembly of the BP210 can lead to misalignment and premature wear of internal gear sets.

Symptoms of Failure

When the ZF 4681.183.001 LOOSE PARTS kit is missing or its components become fatigued, operators typically notice three distinct failure modes. First, external oil seepage around the transmission housing joints occurs because the included fasteners lose clamping force, allowing gaskets to fail. Second, intermittent gear slipping under moderate torque can develop as the HOUS.FRONT SECT shifts out of alignment due to loose mounting hardware. Third, abnormal vibration during gear engagement is a common complaint, indicating that the HOUSING REAR PART is no longer rigidly connected. In advanced cases, a rattling noise from the bell housing area suggests that the HOUSING REAR SECTION has lost its structural integrity due to missing or damaged loose parts.

Technical Specifications

Compatibility

This genuine ZF 4681.183.001 LOOSE PARTS kit is engineered primarily for the BP210 transmission series. Based on its structural role, it is also compatible with the WG180, WG200, and WG210 series where the housing architecture shares identical bolt patterns and pin locations. The kit is frequently specified for use with the TRANSMISSION HOUSING and the HOUS.FRONT SECT in both on-highway and off-highway applications. Always verify your transmission model number before ordering to ensure correct fitment.

Frequently Asked Questions

Q: Can I use the 4681.183.001 kit on a WG200 transmission?
A: Yes, the kit is compatible with WG200 and WG180 series transmissions that share the BP210 housing architecture. However, always cross-reference your transmission serial number with the included bolt lengths and pin diameters.

Q: What is the typical service interval for replacing these loose parts?
A: ZF recommends replacing all loose hardware in this kit whenever the transmission housing is removed for major overhaul, typically every 500,000 km or after significant impact damage. Reusing old bolts can lead to torque loss and oil leaks.

Q: Does this kit include the screen sheets listed in the related components table?
A: No, the 4681.183.001 kit contains only the loose fasteners, pins, and fixing plates. Screen sheets such as 4657301032 and 4657301033 must be ordered separately for complete filtration system restoration.
