General information about this item

Product info
The original BMW drive spline 4-0635 (identical in construction to 2-0735) serves as a coupling flange for torque transmission in the rear axle drive of the BMW Isetta and has been reconditioned with aligned drive arms and a tested shaft mount. Wear on the running surface of the shaft seal can be remedied during restoration using the shaft protection sleeve 4-0636, allowing the original flange to be reused. This ensures that the drivetrain remains free of play, leak-proof, and true to the original.
