This 1-1/16”-16 Tap is a component of the tooling designed for servicing injector sleeves in Caterpillar 3126B (3-valve) engines with stainless steel sleeves. It is included in The Complete Caterpillar 3126B Series Kit with Toolbox (451-6581-00) and is used to thread the upper end of worn injector sleeves to facilitate their removal.

This specialized 1-1/16”-16 Tap is an essential tool for the removal of old injector sleeves in Caterpillar 3126B (3-valve) engines equipped with stainless steel sleeves. This tap is a key component of The Complete Caterpillar 3126B Series Kit with Toolbox (451-6581-00), a comprehensive set for injector sleeve service on these engines.

The primary function of this tap is to cut threads into the upper end of the worn injector sleeve. These newly created threads provide a secure point of attachment for the Sleeve Removal Tool (437-6582-30), also included in the kit, which is then used to grip and pull the old sleeve out of the cylinder head. The kit also contains a Tap Guide Bushing (437-6581-40), which is used in conjunction with this tap to ensure it starts straight and remains properly aligned and centered within the injector bore during the threading process. Other tools in the kit include a Casting Cleaning Brush (450-6951-05) and a Drive In Tool (437-6581-80) for installing new sleeves.
