Abstract
A tool for installing and torquing a tensioning nut onto a tie rod of a shroud repair apparatus. The nut torquing tool has a socket for coupling with the tensioning nut and an adaptor for coupling with a manually operated handling pole, wherein the axis of rotation of the socket is radially displaced relative to the axis of rotation of the adaptor. The respective shafts connected to the socket and adaptor are coupled by means of a pair of sprockets and a chain which convert rotation of the adaptor into rotation of the socket. The distance between the sprockets can be adjusted to tension the chain. The handling pole adaptor is connected to a drive shaft by way of a universal joint, a torque limiter and a torque multiplier. Incorporation of a torque multiplier facilitates installation and torquing of the tensioning nut in a single operation using a lightweight handling pole.
