    How do you*remove this chain guide pin?

    This is a threaded pin and I can't seem to figure out how to remove it.
    My fear is that a pliers will gouge it. The other chain guide pins have nice hex fitting so easy to remove.

    Ideas? Thanks!

    BTW, that crankshaft end bolt was a MF to break free.

    No idea. But I have brand new febi chain guides I'll sell you for cheap if you need em!

    If nothing else pops up, grind a nice straight slot into it and use a screw driver. A dremel cutting wheel should be sufficient.

    Why do you need to remove it? I think it's a press fit ... drive it out from the inside of the block, or some sort of gear puller ... are you removing the crank?

    The block is going to the machine shop for a refresh. So, yes, the crank is coming out although not by me. I'll drop off the short block and the machine shop will do the block, crank, rods & pistons.
    You are correct. RealOEM calls it a "bolt" but the picture on ECS shows a press fit stud (11111748989).

    Press fit, cool it and heat the plate then tap it out

    As others stated there's no need to remove that pin. The crank nose bolt actually isn't difficult if you use a proper holding tool to keep the crank from rotating. I bought a SIR Tools crank holder for $50-60 or so and have used it several times over the years. Makes the job a breeze.

    Yes, I know the tool. In hindsight I would have purchased. I got the bolt free by shimming the crank counterweight to lock the crank and using a cheater bar extension on the breaker bar.
