1.After the bearing is off the rotor, unlock the inner bearing that secures the tine assembly.

2.Remove outer free-wheeling tine assembly.

3.Place the new rotor assembly beside the old assembly so that you have a pattern to follow indicating the correct direction which the new tines are to be installed. You can also refer to the tines on the fixed tine assembly as an example of proper assembly.

4.Once the tines are installed on the free-wheeling assembly, re-install the inner and outer bearing assemblies on the free-wheeling assembly with the bearing hubs facing toward the fixed tines. Make sure that the inner bearing has a locking collar. Hand tighten the nuts only.

5.Slide the new free-wheeling tine assembly on the shaft making sure that the tine direction matches the direction of the fixed tine assembly. The bearing with the locking collar faces the fixed tines and butts up against the shoulder of the shaft.

6.Tighten the four nuts on the bearing assemblies.

7.Lock the bearing collar in place with the hammer and punch making sure the collar locks in the same direction as the rotation of the rotor.
