How do I remove Shimano cassette pins? Help!

[cpml123]

I bought a 10 speed Shimano Ultegra CS6600 15-25 cassette to try to make my Sunrace 11-40 cassette's first 4 cogs more useable. However, I didn't know 16 to 21 cogs are pinned together until I got the cassette.

So now I am thinking either to abandon the project and sell the cassette on ebay. Or I can try to remove the pins to free up the cogs. What have you guys tried? Help!

you should be able to just press those pines out but I imagine if you didn't know that then you probably don't have the tools to perform such a task. The smooth controlled method would be to do it with a press but you could probably get away with a solid surface and a quality pin punch and a hammer, don't forget the safety glasses.

Wouldn't those be swaged? You would need to remove the head, as it is wider than the hole, if that is the case.

I had to look up the word "swaged." It does look like the pin head is on the smaller cog side because it's slightly bigger than the other side.

Use a Dremel tool with a small cutting wheel to cut the pins under the large cog. The spacer would be partly cut through.

Success! @RojoRacing thanks for the pointer on machine shop. I located a local machine shop. Went to a grocery store and bought 6 pack of beer. Went to the machine shop and offered to trade the beer for work. 5 min later it's done!

Would you need 12 or 24 icing covered donuts to do that job???

I didn't think of that... will try donuts next time. Probably a more employer friendly choice.

Donuts are good. When I was putting my S30 together, I was having fits getting the front derailleur right. I offered to bring the LBS mechanic donuts and coffee one Saturday morning, before the shop got busy, if he would let me ask questions and watch him adjust both derailleurs. Worked out well.
