14mm Spark Plug thread repair using Time-Sert kit #4412-321

How to use the Time-Sert kit #4412-321 to repair a 14mm spark plug hole thread. In this video I show you how on the Kawasaki KZ1000 Police P21 cylinder head. It is off the cylinder block so it's easier, but this kit is designed for use in situ when a spark plug thread is damaged but not completely obliterated. The tap self-aligns and allows a straight tapping operation so the hole is square. 00:00 Intro 01:07 Prepping the old threads 01:25 Discussing pros and cons 02:52 Showing the Time-Sert kit 04:35 Inserting the tap into existing threads 05:25 Driving the tap cutting new threads 06:31 Using the counterbore tool 09:03 Prepping new threads for insert 09:20 Going over instructions for insert 10:13 Installing insert 11:25 Using driver to install insert 12:39 Examining finished insert 12:54 Installing spark plug new threads 13:15 Looking at insert from inside 14:16 General discussion and points 15:21 Outro
