Overview
The ZF 0750.115.605 RUNNING DISK is a critical friction component engineered specifically for the BP210 and BP230 series transmissions. This OEM genuine part sits within the clutch pack assembly, where it manages torque transfer and ensures smooth gear engagement under heavy load conditions. As a consumable wear item, the SKU 0750.115.605 directly influences the hydraulic clamping force and rotational stability of the planetary gear sets. When this running disk degrades, it compromises the entire transmission’s ability to maintain consistent power flow, making it a key replacement part during a major overhaul of the TRANSMISSION HOUSING or the HOUS.FRONT SECT.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn running disk causes the clutch pack to slip, resulting in a noticeable lag when shifting from neutral to drive or reverse.
- Transmission overheating: Excessive friction from a glazed or warped disk generates abnormal heat, often accompanied by a burnt smell from the transmission fluid.
- Intermittent loss of power under load: As the disk loses its friction coefficient, the transmission may momentarily lose torque delivery, especially during uphill climbs or heavy towing.
- Metallic debris in the oil pan: Fragments from a disintegrating running disk contaminate the hydraulic circuit, often requiring simultaneous replacement of the CASE and a thorough system flush.

Compatibility
This running disk is a direct fit for the ZF BP210 and BP230 series transmissions, commonly found in medium-duty commercial vehicles and industrial machinery. It is also compatible with the WG180 and WG200 series, where it serves the same function within the forward clutch drum. For a complete rebuild, always inspect the HOUSING REAR PART for scoring or wear, as misalignment can accelerate disk failure.

Frequently Asked Questions
Q: How do I know if the 0750.115.605 running disk needs replacement?
A: Measure the disk thickness with a micrometer. If it is below 2.2 mm or shows visible glazing, it must be replaced. Always pair this with a new FIXING PLATE to ensure proper clamping force.
Q: Can I reuse the old running disk if it looks clean?
A: No. Running disks are sacrificial components. Even if they appear intact, the friction material has undergone thermal fatigue. Reusing them risks slipping and contamination of the CASE with debris.
Q: Is the 0750.115.605 compatible with the WG200 transmission?
A: Yes. The WG200 uses the same clutch pack dimensions as the BP210/BP230. However, verify the stack height using the service manual, as the HOUS.FRONT SECT may have slight casting variations.
