Polan 2150 How to remove old piston

[Michael Kent]

How do I remove the pin that goes through the piston to change piston? I think its called a wrist pin? I have a new piston, cylinder, pin and clips, however the old clip doesnt appear to be the type you can squeeze and pull out. I believe I broke out the one side that has the divot. But cant seem to grab ahold of the clip from the other side. Whats the secret guys? How do I get the stock clip out and drive the pin out and replace piston with the new clips?
The new clips can be squeezed, these old have nothing to grab ahold of. Please help!
Thanks

Run a fine pick under it and watch it fly.

The clip must be burried on other end of pin, I cant even see the clip end to pick! I guess I need to get a scratch all “ice pick”. I already bent the ends of my great grandfathers starret metal compass, dumb ass me. I had nothing else to try. Very frustrated!

Ya, well it would be nice to find a end to pick under, I think my crankcase ate the clip from the one side. Damnit! Now I need to make sure I retrieve this clip somehow?

If it's a clamshell, you should have the bottom off.

The lower half is the crankcase. Check to make sure muffler doesn't have a rattle

Heres the photo of the pin, do you see a clip?
Also what the hell is this rubber gasket for that fell out when I turned the saw over?

 

[Michael Kent]

Why do I need to disassemble more, I took the top cover off and muffler and carb, then unbolted the head from bottom and slid the head off? I just need to remove pin, insert new pin and piston/rings and bolt down the clyinder again. Am I missing something, if so please explain?

I remember this saw, this is the one I said pull the muffler and inspect the piston way before the thread got to almost 80 replys and guesses. Good to hear you found you a top end kit.

Looks like a clip toward the bottom of the wrist pin but hard to tell. From where, roughly, did that seal drop from? Not out of crankcase.

[Michael Kent]

Yes sir this is me, I ordered the top end kit, very happy. Just trying to figure out how to grab the clip?

 

[Michael Kent]

Im thinking the seal was from the case or outer shell. Not sure, it just fell off when I turned the saw over to try to shake out the clip from the engine case after the one clip broke apart.

 

[Michael Kent]

I might have to get out the exploded view of saw to id this seal?

 

[Michael Kent]

Is the clip burried in a carbon deposit on the other end? See photo

Well, if I'm not mistaken, that's a clamshell engine. Only 4 bolts hold the bottom half to the frame. You will need to be sure you seal the bearing/seal assembly to the lower and upper with sealant. Along with the case halves. I've never tried cheating on those in fear of a leak.

And yes, thanks to all who followed my thread and helped. Piston was inspected like you told me and the scoring was noticed. So here I am now

It's possible, need to be clean. If you have a seal pick set, would make it easier to remove those clips, it can get under them.

Oh good god, what have I unleashed? Yes it seemed to simple to be true to disassemble. Yes I believe the whole dang engine is loose after taking the 4 cylinder bolts out. What the heck do I do now aside from getting the wrist pin out. I bought some ultra copper high temp rtv.
