Overview
This genuine ZF 0636.610.104 STUD is a precision-machined locating pin engineered for secure component alignment within heavy-duty construction machinery transmissions. Specifically designed for the differential assembly area, this stud ensures that critical drivetrain components remain properly indexed under extreme torque loads. The SKU 0636.610.104 serves as a fixed anchor point, preventing rotational displacement of mating parts during high-stress operations. When paired with a 2093109029 DIFFERENTIAL, this stud maintains precise gear mesh geometry essential for power transfer efficiency.
Symptoms of Failure
- Transmission housing misalignment noises: A worn 0636.610.104 stud allows the differential assembly to shift, producing metallic clunking sounds during load changes.
- Premature bearing wear: When this stud fails, the 0750117075 TAPER ROLLER BEARING experiences uneven loading, leading to accelerated fatigue and eventual seizure.
- Oil seepage at mounting points: A loose stud compromises the seal between the 2093309078 DIFF.HOUSING and the transmission case, causing gradual lubricant loss.
- Intermittent drive engagement: As the stud loosens, the 2093209094 DIFFERENTIAL may intermittently lose axial location, resulting in momentary power loss during acceleration.

Compatibility
This genuine ZF stud is primarily used in the WG180, WG200, and WG240 series transmissions found in wheel loaders and excavators. It also appears in certain off-highway truck models utilizing the ZF 4WG-200 and 6WG-310 power shift transmissions. The 0636.610.104 stud directly interfaces with the differential carrier assembly and must be torqued to factory specifications when replacing the 2097309085 DIFFERENTIAL AXLE or associated bevel gear sets.

Frequently Asked Questions
Q: Can I reuse the 0636.610.104 stud during a differential rebuild?
A: No. This stud is a torque-to-yield fastener that permanently deforms during installation. Always replace it with a new OEM part to maintain clamping force integrity.
Q: What torque specification applies to this stud?
A: ZF recommends 85 Nm + 90° angle tightening for the 0636.610.104 stud when installed into the differential housing. Always consult the service manual for your specific transmission model.
Q: Does this stud fit the WG180 transmission?
A: Yes. The 0636.610.104 is a standard component in WG180, WG200, and WG240 series transmissions. Verify your housing casting number to confirm compatibility with earlier production runs.
