    Posted: 05 Apr 2010 at 8:21pm

Was going to try and take the seat apart on my D17 as all the rubber grommets and bushings are all worn out.  Anyone have a trick to removing the spring pins out of the three spots so I can drive those 1/2 rods out to dissassemble the seat.  I tried to drive them out with a punch and they just mashed over.  I tried to drill them, but because they're hardened.  I might as well move the seat right next to the bench grinder as I will be sharpening drill bits for eternity.  Was wondering if someone who already took theirs apart found a trick to it?   Thanks.

Chuck - no real "trick" that I know of...btdt... soak them in PB Blaster, etc. repeated for a long time first.  Just cut them off flush on both sides so the don't mash over and use a very good punch and a BFH...when they don't budge, soak some more, give some more time and come back another day and repeat...its what it took for me.  Mike

Chuck, try using a roll pin punch.  It has a tit in the middle of the punch to keep it centered in the roll pin.  Less chance of mushrooming the roll pin.  You can get complete sets of roll pin punches or purchase them individually from your favorite tool salesman.  Got mine from Snap On.  They work really well.  HTH

Forget driving the roll pins out....take a big hammer and punch and drive out the 1/2" pins while shearing off the roll pins. If you then want to attempt to drive out the roll pins, they may cooperate, but I usually installl new 1/2 pins and tack weld them in place anyway.

It is best to support the workpiece against a solid surface. Use a short drive pin punch to get the pins started. Then use a longer one to finish removal. HTH Tracy Martin

I've saved several hours in several places on 45's with roll pin punches, you must hit a solid surface, wise investment.
