Aftermath - Wrist Pin Clip failure

[John Lyngdal]

Here's what I found on a Stihl 034 with a 20" $40 garage sale purchase...



Compression was about 80 psi, so I knew it had issues. But at the price, the salvage parts were worth the asking price. Found pieces of the clip in the crankcase, but all the damage was delivered to the piston and cylinder wall. Cheap wrist pin retaining clips are a bargain with the devil.

Saw that of a few saws posted on here, all aftermarket cir clip failures.

Glue a magnet in the crank case, just in case one falls out on the rebuild, maybe the engine will loose power before the wrist pin gets the cylinder.

You mean it falls out before the saw gets put back together?

Hell, I would shoot the mechanic!!!

Hard to feel too sorry for someone that would put a saw back together with a wispy Chinese pubic hair.
If one has to "rebend" the clip so it will sit tight in the slot, should not be too shocked when it falls out.

That's what the magnet is for, to catch that China clip.

I've always wondered what they use to make the clips.

I just want to add that my last Chinese wrist pin was a bit to long like a lot to long so how often do u think that happens? Make sure the clips fit real well before putting the thing together or they end up as an imprint on the piston.

I dont think they sell a non Chinese craftsman rebuild kit.

I'm rebuilding one of these. Went to the Stihlership with my list and included the circlips. The dealer didn't know if ordering "1" meant a pair or I had to order two. It surprised me a little but it shouldn't.

 

[Mustang71]

They sell a single circlips? What good would that be. Sometimes common sense needs to kick in.

I don't know! That was kinda my point. I'll either have two or four. I have two of the series to build but I have at least one pair to re-use. The old man that's the "expert" on parts didn't know so I'll work him over if it's not right. I enjoy people like him.

Those Chicom clips act more like lead than spring steel. To date I have never used them, always keep a half dozen 10 and 12 mm clips in the spares box.

They are sold each lol , Stihl don't give you anything extra

 

[dmb2613]

I get 10 at a time , I don't loose many any more after I started using the Stihl tool to install them , they have them in 10 and 12 mm
