- 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.

5.24.23. TimeSerts™️ are the biz! …… Wise choice in deciding to installing in all four cylinders. I’ve used them on a GM 3400 V6 rocker arm bolts holes in the aluminum head, after they were stripped out while doing head gaskets and lower intake manifold gaskets, which these engines are famous for! Just a tip if you ever do GM 3100/3400 V6 motors, buy the Lisle 48000 rocker arm tool to relieve spring tension so you can pull the pushrods out in order to change out the lower intake, manifold, gaskets, or doing head gaskets pulling their heads! Saves having to pull the rocker arms off.
Very informative video Tom. Enjoyed the video and RIDE SAFE OUT THERE!
Great video, especially as I have some insert to do myself! The insert kit seems to be a quality kit! Thanks
Very good explanation and how too video it may come in handy some day.
I wonder if there's something like a time-sert than would sleeve things down for a 12 or 10 mm thread diameter plug.
Some cars with bad plug threads will shoot the plug right through the hood like a rifled slug on the power stroke. I hate having my leg (and more sensitive parts) above the bike's spark plugs unless the threads are top notch!!!
Time-Sert makes repair kits for all common or standard sizes.

That's the kit I have, Time-sert has numerous kits, several different 14mm configurations.
Aluminium or Aluminum, metric or imperial?
All of the above. We don’t discriminate based upon material or measure units. Lol.
