ZF 0501.324.869 DISC | OEM Genuine Part

Overview

This OEM genuine ZF 0501.324.869 DISC is a critical friction component engineered for the clutch packs within heavy-duty ZF transmissions used in construction machinery. Positioned between steel separator plates, this disc ensures smooth torque transfer and reliable gear engagement under extreme loads. The SKU 0501.324.869 is precision-manufactured to OEM tolerances, guaranteeing consistent clamping force and heat dissipation. When paired with a properly functioning 5838109009: DIFFERENTIAL, this disc helps maintain driveline integrity during demanding excavation and grading operations.

Symptoms of Failure

When the ZF 0501.324.869 DISC wears beyond service limits, operators often report delayed gear engagement or a noticeable “slipping” sensation when the transmission shifts under load. Another common symptom is erratic clutch chatter during low-speed maneuvering, which can be mistaken for driveline backlash. As friction material degrades, you may also observe darkened or burnt transmission fluid with a distinct acrid odor, indicating excessive heat generation. In severe cases, the disc can cause intermittent loss of drive in specific ranges, particularly when the transmission is hot. These failure modes are often accelerated if the adjacent 0750117075: TAPER ROLLER BEARING has developed excessive play, misaligning the clutch pack.

Technical Specifications

Compatibility

This disc is primarily designed for ZF WG180 and WG200 series powershift transmissions, which are widely deployed in wheel loaders, dozers, and telehandlers. It also fits select variants of the ZF 4WG-200 and 4WG-310 models used in medium-sized construction machinery. For proper clutch pack assembly, always inspect the 2093209023: DIFFERENTIAL and the 5838300626: DIFFERENTIAL HOUSING for wear or cracks during replacement. Compatibility should be verified against your transmission’s serial number plate, as internal clutch counts vary by build specification.

Frequently Asked Questions

Q: How do I know if the ZF 0501.324.869 DISC is the correct thickness for my clutch pack?
A: Measure the total stack height of all discs and separator plates against the service manual specification. A new disc should measure approximately 3.5 mm. If any disc is below 3.2 mm, replacement is recommended to prevent slipping.

Q: Can I reuse the old separator plates when installing this disc?
A: It is strongly advised to replace separator plates simultaneously, as they develop heat checking and warpage. Reusing worn plates will accelerate wear on the new 0501.324.869 disc and may cause premature failure.

Q: Does this disc require a break-in period after installation?
A: Yes. For the first 10 operating hours, avoid sustained heavy loads and high-speed operation. This allows the friction material to bed evenly against the steel plates, ensuring optimal bite and longevity.
