Sleeve Hammer Tool Assembly for CAT

The Sleeve Hammer Tool Assembly is utilized in the servicing of injector sleeves in specific Caterpillar engines, including 3114, 3116, and 3126 (2-valve) engines with copper sleeves, and 3406E engines with stainless steel sleeves. It plays a key role in the installation of new sleeves.

The Sleeve Hammer Tool Assembly is a specialized tool employed in the process of installing injector sleeves in certain Caterpillar engines. It is specifically designed for use with:

• Caterpillar 3114, 3116, and 3126 (2-valve) engines equipped with copper injector sleeves.
• Caterpillar 3406E engines that utilize stainless steel injector sleeves.

For the installation of new sleeves in Caterpillar 3114, 3116, and 3126 (2-valve) engines, this Sleeve Hammer Tool Assembly is used in conjunction with the tip expander driver (437-6551-25) and the tip expander (437-6551-21). The installation procedure involves using the hammer assembly to carefully tap the driver until the tip expander bottoms out on the nose of the replacement injector sleeve. This action is designed to precisely expand the smaller end of the new sleeve, ensuring a secure fit within the cylinder head. It is noted that applying an anti-seize compound to the expander tip may facilitate this process.
