Handbrake gear (EMF) BMW E65 E66

Problem: A characteristic cracking sound when trying to put the handbrake on a BMW E65 or a “Parking Brake Fault” error usually means that the plastic gear inside the actuator has collapsed. The manufacturer does not sell the gear separately, offering to replace the entire EMF unit assembly. Buying a used block is a lottery, since the gear in it may be on the verge of wear. Solution: This digital 3D model is an enhanced copy of the original gear (mechanism code 34436782755). The geometry of the teeth is optimized for 3D printing, which allows you to restore the functionality of the handbrake without purchasing expensive components. Model specifications: Compatibility: BMW 7 Series (E65, E66, E67) - 730i, 740i, 745i, 750i, 760i, 730d, 740d, 745d. OEM Unit code: 34436782755, 34436779451, 34436771129. Purpose: Restoration of the electromechanical parking brake. File format: STL (tested, ready to print). 3D Printing Recommendations: The part operates under very high mechanical load: Material: Only engineering plastic is recommended - Nylon (Nylon) or PA6-CF/GF (carbon fiber). This will provide the necessary viscosity and strength. PETG or ABS can only be used as a temporary solution. PLA is strictly prohibited. Filling: 100% (Solid). Layer height: 0.1 – 0.12 mm for perfect adhesion. Post-processing: Mandatory cleaning of the gearbox from fragments of the old part and the use of high-quality graphite or lithium lubricant. Benefits: Savings: Repairs cost 50-100 times less than purchasing a new unit. Reliability: When using Nylon, the part lasts longer than factory plastic.
