Robot Coupe CL50 Shaft pin

<div> I tried hammering it out with screw and hammer but looks like its seized inside the shaft.</div>

A screw? REALLY?! A SCREW is NOT a proper pin punch tool. DON’T DO THAT!

Get you a quality set of pin punches. Use the largest size punch that will j-u-s-t fit inside the hole your broken pin is in. Cradle the shaft on a metal base such as a close brass nipple with the hole that the pin is in centered over then opening of the nipple. The nipple itself should be set upon a THICK metal table or concrete (I’ve used parking curbs on occasion).

All this is so you have a solid, immovable platform, a place for the pin to push through into…and an anvil under the shaft that won’t harm the shaft.

THEN, use a decent sledge hammer to pound away at the pin punch.

Don’t forget to wear some safety goggles while doing all of this.

Here are tools similar to what I own to accomplish such a task:

Sledge Hammer

Pin Punch set

Hitting the pin with a screw or undersized punch will swell the pin and make it tighter. I preferer a hydraulic press or bearing press for this when possible. Lot more control and less distortion.

It just a long shaft phillips screwdriver. The screws are located under the foot pads. They just pull out and then there are the four screws.
