4.8 Thread

Repairs

General Information

The thread repair process involves a solid, thin walled, self-locking, carbon steel, bushing type insert. During the insert
installation process, the installation driver tool cold-rolls the bottom internal threads and expands the bottom external
threads of the insert into the base material. This action mechanically locks the insert into place.

This Section describes the recommended method of repairing threads in three specific areas of the engine.
•

general thread repair,

•

cylinder block main bearing cap bolt hole thread repair, and

•

cylinder head bolt hole thread repair.

For detailed descriptions of all thread specifications used refer to 4.9

Thread Repair Specifications.

The drill-bit and counter-bore tool from the thread repair kit, Tool No. J-42385-700 and J-42385-2000 are designed for
use with either a suitable tap wrench or drill motor. Limited access and larger hole repair may process better using a tap
wrench. An extension from Tool J 43965 may also be required to drive the thread repair tooling dependent on access to
the hole being repaired. Use only a tap wrench when tapping the hole and during installation of the insert.
