    Notice: failure to torque the cinch bolt to 1.5N-m may result in inadequate fit

    This ultra duty SINGLE-HORN aluminum servo arm is CNC-machined from a solid billet of 7075-T6 aircraft aluminum, broached for the standard 25T spline, and threaded 6X on 5mm centers for M3 linkage hardware.

    Installation

    Fitted axially on a nominal 6mm diameter, 25T-spline shaft (lightly greased), secure axially with a stainless steel M3x6 socket cap (Allen) machine-thread bolt torqued to 2.0N-m. Then cinched radially with a stainless steel M2.5 socket cap (Allen) machine-thread bolt torqued to 1.5N-m.

    Disassembly is the reverse, e.g. first loosen cinch bolt, remove axial bolt, then remove arm.
