AIM hydraulic quick coupler too wide for thumb - how to shave 10mm off the inside of the thumb ears

[crazydane]

Just got my AIM QC for my TB260. Unfortunately, its 10mm too wide and my TAG thumb won't slide over it.







So I guess take out the grinder and start grinding away at the inside of the thumb boss on the side with the lock pin?

I'm guessing the coupler side would be easiest to put on a mill if you can find a machinist If it needs to be quick and dirty a cutting wheel on a 6 inch grinder and try your best

3m disks are the best spendy but well worth it https://www.zoro.com/3m-cubitron-6x...VGWlHAR1s9QRzEAQYASABEgIH4PD_BwE&gclsrc=aw.ds

Turns out I could fit the thumb onto my cut off saw:



It was a chore to cut and the thumb and/or saw would move as I was cutting. When I was done, I was shocked to discover I had cut off 20mm instead of 10mm. I did a little bit more than 10mm on purpose as I wanted to make sure it would slip on. I guess there was just a lot of wobble in the abrasive disk.

Anyway, as it turns out, the piece I cut off made for a nice washer to make up for the gap:



I suppose I could weld it back on one day, but having a thick washer should work just as well I would think.
