Overview
The ZF 4681.298.001 CASE is a precision-engineered structural component designed specifically for the BP210 and BP230 series transmissions. This OEM genuine part encloses and protects the internal gear train, clutch packs, and valve body assembly, ensuring correct alignment and oil retention under high-torque conditions. As a critical housing element, the 4681.298.001 CASE works in concert with the TRANSMISSION HOUSING (4681101002) to form a sealed, rigid chassis that withstands torsional stress and thermal expansion. The SKU 4681.298.001 is machined to exact OEM tolerances, guaranteeing a direct fit without modification.
Symptoms of Failure
- External oil seepage around the case mating surfaces: A cracked or warped CASE allows transmission fluid to escape, leading to low fluid levels and eventual overheating. This is a common long-tail search query for “ZF BP210 oil leak from case housing.”
- Gear engagement hesitation or slipping: When the CASE loses structural integrity, internal shaft alignment shifts, causing delayed shifts or unexpected gear disengagement under load.
- Abnormal vibration or whining noise during acceleration: A compromised CASE fails to dampen gear mesh harmonics, producing audible metallic sounds that worsen with RPM.
- Contaminated fluid from debris ingress: Cracks in the CASE allow dirt and moisture to enter the transmission, accelerating wear on clutches and bearings.

Frequently Asked Questions
Q: Can the 4681.298.001 CASE be reused after a transmission rebuild?
A: It is strongly recommended to replace the CASE with a new OEM unit during a full rebuild, as thermal cycling can cause microscopic warping that compromises sealing. Always inspect for cracks or distortion before reuse.
Q: Is this CASE compatible with the ZF WG180 series without modification?
A: Yes, when paired with the correct front and rear housing sections (4681201007 and 4681201008), the 4681.298.001 CASE fits the WG180 and WG200 series. Ensure the cylindrical pin (0631306074) is installed for proper alignment.
Q: What torque specification should be used for the cap screws securing this CASE?
A: Use 45 Nm (33 ft-lbs) for the M10 cap screws (0636100801) and 25 Nm (18 ft-lbs) for the M8 cap screws (0636100803). Apply medium-strength thread locker to prevent loosening from vibration.
