Worn diverter valve in sick faucet that redirects water to hand sprayer.

2. I then located what where hand spray diverter valve was located. I had assumed the diverter valve was in the remote faucet value housing, but instead found the diverter within the faucet spout.
3. Since the faucet water control valve was mounted separately from the faucet spout, I did not turn off the hot and cold-water supply valves under the sink. Next, I removed the Allen set screw on the faucet spout and carefully lifted the spout from the faucet spout core body assembly. A small amount water is normally within the faucet spout and emptied onto the sink lip.
4. Next, I removed the small spit ring in the faucet neck assembly. I found my split ring plier jaw points were too big to grasp the split ring end holes. Instead I used two small straight end stainless steel probes to carefully compress and remove the split ring without damage to the split ring or the faucet assembly core.
5. Then I located the diverter valve and attempted to remove it with small needle nose pliers. The diverter valve was stuck and could not be removed without possible damage to the existing diverter value. Instead I used a small 90-degree stainless steel probe to loosen the diverter valve and remove it with the small needle nose pliers.
6. I inspected the 2 O-rings and diverter value but did not see any visual problems or damage to these parts. I reused the 2 O-rings but replaced the diverter value on suspicion.
7. Next I cleaned the faucet parts with a paper towels then re-lubed all those parts with silicon grease I had removed.
8. I reinstalled the faucet spout, opened the faucet valve, checked for presence of any water leaks and tested the new diverter valve. There were no presence of any water leaks and the faucet worked again as when it was new.
My previous single handle Delta kitchen faucet had the diverter valve mounted in the value assembly not the faucet spout. My repaired Kohler kitchen faucet had the valve assembly remotely mounted within the faucet sink spout, so this repair was new for me. Thanks to the e-Replacement web site and their replacement parts diagrams with the associated part numbers. The replacement parts including shipping were far less in cost than a new kitchen sink faucet, and the elapsed time between parts ordering and receipt was only a few days.
