24-1526-060

Torque transmission through the 24-1526-060 shaft section

The 24-1526-060 section operates as a mechanical torque-transmitting element in the tail rotor drive line. During helicopter operation, torque from the main transmission path is passed through the intermediate gearbox and continues through the tail shaft system to the tail gearbox. From there, power is delivered to the tail rotor for directional control. The rear rigid shaft section must maintain stable geometry while rotating under load. Excessive deformation, damage, imbalance or incorrect installation can affect the shaft line and may lead to vibration or abnormal transmission behavior.

24-1526-060 in the 8A-1516-000 tail drive system

The 24-1526-060 section is identified as a component of the 8A-1516-000 tail drive system. This is important when ordering or inspecting the part, because the shaft section is not a complete tail transmission assembly by itself. It belongs to a wider shaft line that includes other sections and installation hardware. In maintenance practice, the part may be supplied as a replaceable spare or as one element within a shaft assembly kit. Before replacement, the installed configuration should be compared with the parts catalog and the actual helicopter tail boom transmission layout.

Installation role of the rear 24-1526-060 section

The rear position of the 24-1526-060 shaft section means that its interfaces and alignment are important for correct torque transfer to the tail gearbox. The part is connected through flanged joints and associated fastening hardware according to the applicable assembly documentation. Correct mounting helps maintain shaft-line alignment, reduces unnecessary vibration and supports reliable operation at high rotational speed. During installation, attention should be paid to flange condition, fastener completeness, mating surfaces, shaft straightness, balance marks and documentation requirements for the complete tail drive assembly.

Application of 24-1526-060 on Mi-series helicopters

The 24-1526-060 rear rigid shaft section is used on Mi-8 family helicopters and related Mi-series configurations. Typical applicability includes Mi-8, Mi-8MT, Mi-8MTV, Mi-17, Mi-171 and Mi-14, depending on the aircraft documentation and installed transmission system. Because helicopters may differ by modification, overhaul history and tail drive configuration, applicability should not be assumed only by visual similarity. The part number, assembly reference and helicopter parts catalog should be checked before supply or installation.

Identification and ordering of 24-1526-060

The shaft section may be referenced under several equivalent designations, including 24-1526-060, 241526060 and 24.1526.060. These designations refer to the same rear rigid tail shaft section, but order confirmation should still include the aircraft type, assembly number and required completeness. If the part is requested as part of a kit, the scope of supplied hardware should be clarified separately. For export or overhaul supply, it is also useful to specify condition, documentation, passport reference and whether the requirement is for the individual shaft section or for a larger 8A-1516-000 assembly set.
