Thank you for your question. The 2:00 mark of the linked video starts the portion that shows how to disassemble a single handle kitchen faucet. http://www.deltafaucet.com/tools-re...
You will need to first shut off the water supply going to the faucet. Next you will need to remove the red/blue indicator button on the front of the handle to access the set screw that when loosened will allow the handle to be removed. Unscrewing the cap assembly will then allow the cam, ball assembly, seats, and springs to be removed.
