Patent ID: 7409935

Claim:
In a camshaft phaser, a method for setting a bias spring torque to a predetermined torgue value wherein a bias spring is operative between a rotor and a stator of said camshaft phaser, the method comprising the steps of: a) fixing one end of said bias spring to a spring retainer; b) fixing the other end of said bias spring to one of said stator and said rotor; c) winding said bias spring by moving said spring retainer relative to said other end of said bias spring; d) monitoring said bias spring torque during said winding; e) stopping said winding when said predetermined torgue value of said bias spring torque is reached as a result of said monitoring step; and f) fixing said spring retainer to the other of said rotor and said stator to transfer said predetermined torque value between said rotor and said stator.
