An official CAA Japan notice concerns Motorcycles (Honda Tact, Dunk) - Repair. Engine (crankcase and transmission case) defect. ■ Defective part (component name): Engine (crankcase and transmission case). ■ Condition of the structure, equipment or performance considered noncompliant with standards, and its cause: Due to improper manufacturing process controls for the crankcase and transmission case, the mating surfaces of these cases may not seal adequately, allowing transmission oil to leak. Inadequate lubrication may then cause abnormal noise. If use continues in this condition, bearings inside the case may fail. In the worst case, the rear wheel may lock while riding, causing a fall. Published 2024-10-31.
What to do now
(Recall notification number) 外ｰ3895. ■ Corrective measures: On all vehicles, measure the transmission oil quantity. If it is below the specified minimum, replace the transmission case with a nondefective part and replace the bearings and related parts with new ones. If it meets or exceeds the specified minimum, clean the mating surfaces of the cases, apply gasket sealant and reassemble. Because preparing the parts will take time, information about the defect will be provided, and further contact will be made as soon as the parts are ready.
