Rigid shaft section
Available on back-order
Description
The 8A-1516-40 rigid shaft section is one of the structural elements of the 8A-1516-000 tail drive shaft assembly installed on Mi-8/17 series helicopters. This segment transmits torque between adjoining tail shaft components and forms part of the power transfer path from the main gearbox to the tail rotor through the intermediate and tail gearboxes.
The rigid section works in combination with articulated shaft elements and support bearings mounted along the tail boom. It is designed to withstand high torsional loading, continuous rotation and vibration across the helicopter’s operating envelope. The component is factory-balanced and includes provisions for assembly lubrication and secure attachment using standard mounting hardware.
The section is installed on Mi-8, Mi-8MT/17, Mi-171/AMT, Mi-8MTV/172 and Mi-14 helicopters and is replaceable as part of transmission overhaul procedures. It is supplied individually or as part of the complete 8A-1516-000 tail shaft set.
Alternate designations: 8A-1516-40, 8А-1516-40, 8A1516-40 — all refer to the same rigid shaft section.
