2001SSTBanshee Posted January 7, 2004 Report Share Posted January 7, 2004 The crank? Quote Link to comment Share on other sites More sharing options...
boonman Posted January 7, 2004 Report Share Posted January 7, 2004 Yes. Take the motor out. Pull the cylinders off, although they are prolly off already. Dump some kerosene down there, and swish it around. Dump it out. Do this 2-300 times. Use compressed air. Then, put it back together. Run it, and smoke the crank. Then split the cases, and get a new crank. Put it back together. All good to go... Your wayyyyyyyy better off to split the case and spend the $25 on gaskets and yamabond than to risk crank failure.

Been there done that!!! When the crank does fail, it will take your new pistons bore and head with it. Quote Link to comment Share on other sites More sharing options...
boonman Posted January 7, 2004 Report Share Posted January 7, 2004 Indeed Rod!!!! Been there and done it to. Went from .020" to .060" in a month. Not a happy camper at that point. Quote Link to comment Share on other sites More sharing options...

silveradohd Posted January 7, 2004 Author Report Share Posted January 7, 2004 Is there anyway to tell if I got any sand in there. Last weekend I was in Glamis, I dropped an air filter and sand got in the cylinder. I definetley need a new top end, just not sure if the bottom end got some sand as well.

boonman Posted January 7, 2004 Report Share Posted January 7, 2004 Do you wanna take the chance? There is a way to tell, rip it down, and take care of it the proper way.... However, before the sand gets to the top of the piston, and into the cylinder, it first has to be drawn into the bottom of the case, so it can go through the transfers. So, yes, sand did get into the lower end. However, it may not have been into the bearings. However, it is not a chance that I myself would be wiling to take...
