Claim 10:
11. A wind turbine drivetrain arrangement, comprising:
a drivetrain including a rotor shaft fixable to a wind turbine rotor hub, a gearbox and a drivetrain housing, wherein the rotor shaft is coupled to the gearbox at a gearbox input coupling, and wherein the gearbox includes an output drive shaft defining a rotational axis;
said drivetrain arrangement further comprising a turner gear arrangement as claimed in claim 1, said transmission assembly of said turner gear arrangement being drivingly coupled to the gearbox output shaft so as to transfer torque to the rotor shaft through said gearbox,
wherein said radial support arrangement of said turner gear assembly is in a fixed relationship to the drivetrain housing and constrains movement of the rotational drive element of said transmission assembly in a direction transverse to its rotational axis.
