Overview
The ZF 0736.101.202 CAP SCREW is a critical OEM genuine fastener engineered for the WG100, WG130, and WG131 transmission series. This cap screw secures the shift system housing and main shaft assemblies within the transmission casing, preventing axial movement and maintaining precise gear alignment. As a high-tensile fastener, it withstands extreme torsional loads and thermal cycling inherent in heavy-duty industrial transmissions. The SKU 0736.101.202 is manufactured to ZF’s exacting specifications, ensuring a perfect thread fit and clamping force when paired with components like the 2094104412: MAIN SHAFT or the 2094304054: MAIN SHAFT.
Symptoms of Failure
- Transmission oil seepage at fastener points: A worn or loosened 0736.101.202 cap screw can compromise the seal between the shift housing and transmission case, leading to slow oil leaks that accumulate on the bell housing.
- Gear engagement hesitation or grinding: When this cap screw loses its clamping torque, the 2094106010: SHIFT SYSTEM components may shift out of alignment, causing delayed or rough gear engagement during high-torque operation.
- Abnormal vibration from the transmission mid-section: A fractured or stripped cap screw allows the 2094206001: GEARSHIFT SHAFT to develop excessive play, producing a distinct low-frequency vibration under load.
- Difficulty shifting into reverse or low gears: Loss of fastener integrity directly affects the shift fork positioning, making reverse and first-gear selection increasingly difficult as the cap screw loosens over time.

Compatibility
This cap screw is specifically designed for ZF WG-series transmissions. Primary compatibility includes the WG100, WG130, and WG131 models. It also fits the WG180 and WG200 series when used in the shift housing-to-main case interface. The 0736.101.202 is commonly replaced during overhaul of the 2094106010: SHIFT SYSTEM or when servicing the 2094304054: MAIN SHAFT assembly. Always verify thread pitch and length against your transmission’s service manual before installation.

Frequently Asked Questions
Q: Can the 0736.101.202 cap screw be reused after removal?
A: ZF recommends replacing this fastener with a new OEM part whenever it is removed, as the thread-locking compound and torque-to-yield properties degrade after initial installation.
Q: What torque should I use for this cap screw?
A: The factory specification is 45 Nm. Always use a calibrated torque wrench and apply a medium-strength thread locker to prevent loosening from vibration.
Q: Does this cap screw fit the ZF WG180 transmission?
A: Yes, the 0736.101.202 is compatible with WG180 models when used in the shift housing mounting points, though always cross-reference with your parts manual for exact location.
