TIME-SERT 4412SRT Taper Seat Recondition Kit

This a taper seat reconditioning kit for M14x1.25 spark plug holes. Unlike most Time Sert kits, this is NOT a thread repair kit, it only restores the taper seat where spark plug seals. See below.

KIT CONTENTS 1. Wrench 2. Driver tool 3. Seat Cutter This tooling is used to recondition seats that have NO INSERT. -WARNING Cutting tools may shatter if broken. The wearing of safety glasses is required in the vicinity of their use.

1. Use WD40 on driver tool. Start driver tool into the hole with wrench provided, continue until the driver tool is approx. ¼ inch below the surface. Leaving the driver ¼ inch below the surface ensures that the seat cutter will not hit the back of the driver.

2. Use WD40 on cutter. Using the wrench provided rotate the seat cutter. After a few turns lift the seat cutter to inspect the seat. Repeat this operation until the seat is cleaned up. :Tip You may tape the seat cutter to the wrench to hold in place for deep holes. REPAIR COMPLETE: Remove seat cutter & driver tool. Spark plug will now seal on new reconditioned seat.
