Caution about aftermarket wrist pin clips

[ZeroJunk]

I rebuilt a MS660 for a contractor about three years ago. Don't remember which top end I used but it had the clips with the tabs on both sides. Ease of installation I suppose. Came back about a year later and one of the tabs had broken off. So, I replaced it with a kit that has the tab on just one side. Came back a couple of years later and one of those tabs had broken off. Metal fatigue I suppose.
The saw has seen a lot of hard use, but everything looks pretty decent for a saw run by a crew who less than gives a crap. If not for those wrist pin clips it would have gone a couple more years anyway.
I know they hate to pay OEM, so I will likely just by OEM clips. Hopefully the groove size will allow it.

The guys using them clips cut those ears off before installation

Been oooodles of threads on the dangers of using aftermarket circlips, do a quick search and explore.

Id rather re-use 20 year old oem circlips than the ones that come from the aftermarket. Though ive heard the ones that come with meteor pistons are good.

If you did a search on every subject chances are there wouldn't be any new threads and they could just archive the whole forum.

I love going back a few years, unfortunately, most if not all pics are lost. I came to AS through google search.

Which oil works best with AM clips and at what ratio? Not really feeling like searching.

STP. 47 1/2 to 1

Gary Goo was the best mix oil ever, use it any ratio , it will deliver excellent results.

Thank you both for the spoon feeding. Any others?

Thing is, nobody knows to do a search if they don't know the problem exists. So, it's not so bad to start a new thread on old problems.

Just stick to oem, or you'll be into it again.

I hear 100:1 oil mix will smoke out any saw. Who cares about clips anyways?

I don't think so on the new ones. Big old double G's.

 

[pioneerguy600]

I personally do not see anything wrong with starting a new thread or even bringing up an old one, new information/developments can always be added to old threads and new threads are answered by members who may not have been a member back when.

 

[grizz55chev]

Wish the pics were still available on some of the old threads,a wealth of info lost.

I’ll say! One that comes to mind for me is a complete tear down and rebuild of a jonsered 590. A beautiful job done with a ton of pics. Gone.

Maybe one day I will do one of mine. I thought that thread would be a great reference for me, but not anymore. Besides, I just liked the brand-new jonsered 590 to look at from time to time. Oh well.

I've been toying with the idea of using Echo clips on those aftermarket pistons, the clips with the two short ears. Would be easier to install than the others and work fine for Echo saws. I think they have two different sizes to choose from..

 

[ZeroJunk]

When the first ear came off I thought it was just a fluke. Bad metal maybe. But, the second on the same saw ?

Real question is why does Meteor, for instance, who makes a great piston still furnish these. The problem is real.

 

[cuinrearview]

I haven't heard of, or experienced issues with Meteor.
