Free-Wheeling Tine Assembly
Removal and Replacement
Complete steps 1 through 12 in previous section, then
proceed with the following:
After the bearing is off the rotor, unlock the inner 1.
bearing that secures the tine assembly.
Remove outer free-wheeling tine assembly.
2.
Place the new rotor assembly beside the old 3.
assembly to have a pattern to follow indicating the
correct direction for the new tine installation. The
fixed tine assembly is also an example of proper
installation.
Once the tines are installed on the free-wheeling
4.
assembly, reinstall the inner and outer bearing
assemblies on the free-wheeling assembly. Face
the bearing hubs toward the fixed tines. Make
sure that the inner bearing has a locking collar.
Hand tighten the nuts only.
Slide the new free-wheeling tine assembly onto
5.
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.
Tighten the four nuts on the bearing assemblies.
6.
Lock the bearing collar in place with the hammer 7.
and punch making sure the collar locks in the
same direction as the rotation of the rotor.
Replace outer shaft bearing and reinstall the
8.
entire rotor assembly by reversing steps 1 through
12 in previous action. Instructions are for one side.
Both side are done with the same procedure.

Handle
Models 424 and 530, Cam Lock
Inspection
The handle cam lock must lock shut under 1.
moderately heavy hand pressure. The handle
frame should be tightly secured to the aerator
body.

2.
by hand when cam is released, the nut must be
replaced to maintain the security of the lock.
Adjustment
With the handle in the operating position, tighten the
cam rod lock nut (¼ turn at a time) until cam handle
locks with moderately heavy hand pressure.

grease on the cam edge.
