The Balance Wheel

Cross-Compatibility & Hidden Traps: Upgrading 4R to 6R or Swapping in an NH35

Best answer · ricardo

Watch out for that tiny, one-way C-clip holding down the first reduction wheel. Also, keep a close eye on the Magic Lever pawl fingers. Make sure you safely unhook the Magic Lever before you pull off the automatic train bridge. If you forget this step, it is incredibly easy to bend or snap those delicate little fingers where they grip the transmission wheel.

Step-by-Step Bench Notes

* **Locate the first reduction wheel:** Keep a close eye on its unidirectional C-clip during disassembly.

* **Inspect the Magic Lever:** Focus on the delicate pawl fingers gripping the transmission wheel.

* **Decouple before lifting:** Safely unhook the Magic Lever from the wheel *before* removing the automatic train bridge.

* **Avoid damage:** Lifting the bridge too early will instantly bend or snap the fragile pawl fingers.
