LAP IT UP
Allen head bolts get stripped out easily. If they are showing signs of wear, before trying to remove them fill the recess with lapping compound then install the proper allen bit. This will make it a little tighter and have better grab so it doesn’t strip as easily. And a similar tip for removing dowel pins in flywheels that are extremely stubborn. We use lapping compound on the pin so it grabs in the collet better. And if you need a little more bite, or if your collet is a little bigger than the pin, use a small washer around the pin. This way the sleeve will go further down the collet making it tighter.
