Sticky Piston Pin

Chuck · Post by **Chuck** » Sat Apr 29, 2006 10:18 pm

Hey all,
I've been trying to change the rings on my newly aquired Spree.
I've got to the point in which I'm to remove the piston pin and I have been able to remove one of the cir clips.
the other however, I am unable to remove.
I'm thinking that it wont come out because the pi is wedged up against it and I can't get a good grip on it with the needle nose.
knowing that I only have to have oone of them out, I proceed to trying to get the pin out with a screw driver, as per the instructions given in this forum.
seems to be stuck.
any sugestions.
I don't want to beat on it cuz I think it might bend the conecting rod.
thanks
chuck

I try to hold the piston stiff while tapping on a screw driver through.

cool,
I'll give it another shot.
I've got the engine off he frame, so maybe I can brace the piston against something.

Victory!
I found that a 3/16 nut driver was the same size as the pin
soes I tip the engine on it's side and prop two two by fours up underneath the cylender and start bangin' away.
I really had to beat the crap out of it though. it seams to me that this shouldn't be normal.
also, I'm having a hard time getting the rings out, as if there is some blackis gooish tarish stuff in there with them
Have I suffered some sort of melt down?

try to clean it off with brake clean or something like that first. Then luightly try to sand the pisto around the rings where you think the aluminum is overlapping and holding the rings in.

I appreciate the help
I'' let you know how it turns out
I'll get my new rings from the bike store on Wednesday
what do you think about using gasket sealer for the bottom?
I've got a new head gasket on the way too

Still having a problem getting those rings out
they're really caked up in there
I baught some of that super penetrating(I said penetrating)oil and rust bolt remover stuff from the auto store

still nothing
it also appears to be a second ring underneath the outer ring
almost like a spring I've been able to break away part of the ring that's more toward the crank case and I can see this spring type thin piece of metal underneath where the piston ring was
I don't remember reading anything about this
anyone have any clues?

Someone ran something gooey through the engine... like premix oil?

Have you tried soaking the whole thing in a solvent like gas or kerosene?

Don't use that make-a-gasket stuff on your engine. Bad bad bad. Stuff gets inside and in all sorts of places it shouldn't. Just clean the gasket surfaces good and run new gaskets.

I'm just so anxious to get this thing on the road

that spring under the ring is like a spacer to give the ring more tension. Some use them and some don't.On a double ring piston if used is used under the bottom ring.

buy paper gasket and you can make one for the base.
