    Was running the D6C on a project about 10 days ago & when I got off I noticed this, a guide plate has 2 bolts either come loose or break off & lost the spacers too. The top two bolts that go into the idler shaft block that splits were both broke too.

    Put things back together the best we could & finished the job till we could get her back for repairs this week!

    First we tried drilling down through the top holes in the guide plate, but no go.....those Gr 8 bolts are HARD!! Even tried getting some heat on them, letting them cool to soften a bit......no luck.

    Once the idler was off we had to remove the one block that the idler shaft goes through. Wedge type key allows removal of the block from the shaft & boy was that nasty to get out! Wanted to get the block on the workbench to drill out the broken off 5/8" Gr8 bolt. Tried doing it on the machine & no go!
