OMG piston skirt.... just saw it


Recommended Posts

k well i was just admiring my banshee right and i was looking at the cylinders and the old pistons and i JUST realized theres a like 1 inch big triangle chunk out of the 1 piston.... thats the metal chunks i saw in the oil... good thing i didnt put the new cylinder sand pistons on and start it lol. but just CANT believed i missed that when i pulled them out

A busted piston skirt would not show up when you drain your oil.....if it did you would have much bigger problems. The metal shavings could be from your clutch plates wearing....tranmission wearing....etc.

same thing i was thinking just a rookie to this tho... :confused:

well if thats the case then you have a giant hole between your crankcase and your tranny. which opens up a whole new set of problems. the crankcase is not connected to the tranny on a two stroke.

 

 

.... how do you figure? the chunk of the piston skirt was ldged in the crank case and then i kicker the kickstart which turned over the crank and mashed up the skirt, has nothing to do with the tranny....

on a 2 stroke there is no oil that goes into your crank case. The oil is for your tranny and clutch. When you drain the oil thats the only place oil come from. The crank case in a two stroe is where the A/F mixture goes in at and the goes up through the transfers to the topend. So any metal from your pistons can not make it into your tranny ( where the oil you drain is at) without a big hole being punched through the metal.

When you say that we all assume that you mean found the chunks in the transmission oil when you drained it since you don't really see any of the two stroke oil unless you take the crankshaft out, there will usually be some sitting in the bottom of the case. In a two stroke motor the crankshaft area and transmission area are completely sealed off from each other, transmission oil only touches the gears and the clutch and the two stroke oil, which is mixed with the gas, only touches the cylinders, pistons, connecting rod, and crankshaft. They never mix since the areas are sealed off from each other (unless you have a hole somewhere which incites a pretty big problem then). In a 4 stroke, the oil that lubricates the transmission and clutch also lubricates the crankshaft, pistons, etc. So then it actually is impossible for you to have found metal shavings from the piston in your trans oil unless 1)you have a 4 stroke motor in your banshee, 2)you have a big hole somewhere and a major motor problem, or 3)a magical fairy put them there.

What they all said. The crank on a two stroke is "dry" It only gets oil from the premix and does not actually sit in any oil. It's separate from the tranny so if you have piston in your tranny you have a big hole in your cases between the two.

 

And if you had piston skirt in your crank and kicked it over and ground it up you better split your cases and pull that crank. It's going to need hella cleaning to get all the pieces out or it will get ruined quickly.

i didnt say i drained my oil after i turned the engine over i ahd a bit of oil sitting in the bottom of the case because it dripped in from before when i lubricated the piston rings and cylinder but i ended up taking the pistons off again so thats ow the oil got in therenothing to do with the transmission

Well that makes a little sense now and I would still pull that crank and clean all the bearings very well.
