Dowel Pin Puller Slide Rod

The Dowel Pin Puller Slide Rod is a central component of the Van Norman Dowel Pin Puller Kit (794-8684-78). This rod serves as the crucial link between the slide hammer mechanism and the various collets used to grip and remove dowel pins from engine components.

The 794-8688-45 Dowel Pin Puller Slide Rod is a key element in the operation of the Van Norman Standard and Metric Dowel Pin Puller Kit (#794-8684-78). Its primary function is to provide a sturdy and reliable connection between the slide hammer and the collet that grips the dowel pin being extracted. The slide rod transmits the impact force generated by the slide hammer to the collet, enabling the removal of tightly fitted dowel pins.

Here’s how the Slide Rod interacts with other components:

1. One end of the Slide Rod is designed to be engaged by the Slide Hammer (794-8688-44). The slide hammer slides along this rod to generate the necessary pulling force.
2. The other end of the Slide Rod is where the selected Collet (sized appropriately for the dowel pin) is attached. The Clamp Sleeve (794-8688-46) is used to securely fasten the collet to this end of the Slide Rod.
3. When the slide hammer is used in an upward motion, the force is transmitted through the Slide Rod to the collet, which is gripping the dowel pin, thus pulling the pin out of its location.

The Dowel Puller Slide Rod is engineered for durability and strength to withstand the repeated impact forces generated by the slide hammer during dowel pin removal. Its precise dimensions ensure proper alignment and secure connection with both the slide hammer and the collets, contributing to the overall effectiveness and reliability of the Van Norman Dowel Pin Puller Kit.
