I dropped a piston yesterday, it landed on the engine stand and took a chip out of the bottom of the piston skirt (the long side). The cylinders are in great shape, the pistons were in fine shape too, this was supposed to be a quick clean and new gaskets and back together. So, can I still use the piston or is it toast? | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | Photos of the damage would be nice.  My gut says no, get a new one.

If it's anywhere on the skirt at right angles to the wrist pin, that's a thrust-bearing area. If so, make it an expensive paperweight! Jerry

I put a picture of it in my photobucket, just click the link with my name to see the pic. | | | | | Joined: Aug 2010 Posts: 127 Shop Shark | | Shop Shark Joined: Aug 2010 Posts: 127 | It looks like ebay only has pistons for the 37-40 216's, rock auto doesn't sell them, Jim Carter only has over sized sets, so I'd have to rebore my engine. This could be one hell of an expensive lesson. | | | | | Joined: Feb 2004 Posts: 29,746 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,746 | What's the bore size, standard or oversize? I've got a bunch of cast iron 216 pistons sitting around that I'm not likely to use on any of the engines I rebuild. I bore 216's 60 over and use aluminum 235 pistons in them. It keeps Babbit rods from wearing out in a hurry due to the lighter weight of the pistons.
While you're in there, consider installing a set of spring steel "piston skirt expanders". They really quiet the engine down by reducing piston slap, especially after a cylinder gets honed and ends up slightly oversize. There are several sets on Ebay right now, at around $20.00 a set. Jerry

If I remember correctly 41 is different than 37-40, but I don't know about after 41.
