Any suggestions? I've been trying to take it apart now for several months, but I can't seem to find a bolt or allen wrench thats 14mm. Home Depot has every size but that one . So unless anyone has an idea about how to get the piston pin covers off I guess it's time to start thinking about what I should do with it. I'm not entirely sure what all is still good on it. Pretty sure the pistons are shot. but the block might be savable if it had some minor work done to it. I think the crank is ok, from what I can see it doesn't look noticably damaged.
take a bolt with a 14 mm head and lock two nuts together on it and use that. If you have access to a welder tack the nut on. Its what I use.
what I have been trying to do, but I can't find one that size. I've been to two home depots, and a lowes.
Northern Tool carries a hex key set with the size you're looking for. They have it listed for 13.99 for the set. http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_1036623_1036623
